Request parameters
Pagination and filtering parameters can be used with this method.
Response data keys
| Name | Description |
|---|---|
| assureUTF8 | Indicates whether all data retreived from the index is proper UTF8. If enabled (set to True), degrades indexing performance.
This is a global setting, not a per index setting. |
| blockSignSize | Controls how many events make up a block for block signatures.
If this is set to 0, block signing is disabled for this index. A recommended value is 100. |
| blockSignatureDatabase | The index that stores block signatures of events.
This is a global setting, not a per index setting. |
| coldPath | Filepath to the cold databases for the index. |
| coldPath_expanded | Absoute filepath to the cold databases. |
| coldToFrozenDir | Destination path for the frozen archive. Used as an alternative to a coldToFrozenScript. Splunk Enterprise automatically puts frozen buckets in this directory.
Bucket freezing policy is as follows:
If both coldToFrozenDir and coldToFrozenScript are specified, coldToFrozenDir takes precedence. |
| coldToFrozenScript | Path to the archiving script.
See the POST parameter description for details. |
| compressRawdata | This value is ignored. splunkd process always compresses raw data. |
| currentDBSizeMB | Total size, in MB, of data stored in the index. The total incudes data in the home, cold and thawed paths. |
| defaultDatabase | If no index destination information is available in the input data, the index shown here is the destination of such data. |
| disabled | Indicates if the index is disabled. |
| enableRealtimeSearch | Indicates if this is a real-time search.
This is a global setting, not a per index setting. |
| frozenTimePeriodInSecs | Number of seconds after which indexed data rolls to frozen. Defaults to 188697600 (6 years).
Freezing data means it is removed from the index. If you need to archive your data, refer to coldToFrozenDir and coldToFrozenScript parameter documentation. |
| homePath | An absolute path that contains the hot and warm buckets for the index. |
| homePath_expanded | An absolute filepath to the hot and warm buckets for the index. |
| indexThreads | Number of threads used for indexing.
This is a global setting, not a per index setting. |
| isInternal | Indicates if this is an internal index (for example, _internal, _audit). |
| lastInitTime | Last time the index processor was successfully initialized.
This is a global setting, not a per index setting. |
| maxConcurrentOptimizes | The number of concurrent optimize processes that can run against a hot bucket.
This number should be increased if instructed by Splunk Support. Typically the default value should suffice. |
| maxDataSize | The maximum size in MB for a hot DB to reach before a roll to warm is triggered. Specifying "auto" or "auto_high_volume" causes Splunk Enterprise to autotune this parameter (recommended). Use "auto_high_volume" for high volume indexes (such as the main index); otherwise, use "auto". A "high volume index" is typically one that gets over 10GB of data per day.
Although the maximum value you can set this is 1048576 MB, which corresponds to 1 TB, a reasonable number ranges anywhere from 100 - 50000. Any number outside this range should be approved by Splunk Support before proceeding. If you specify an invalid number or string, maxDataSize is auto-tuned. Note: The precise size of your warm buckets may vary from maxDataSize, due to post-processing and timing issues with the rolling policy. |
| maxHotBuckets | Maximum hot buckets that can exist per index. Defaults to 3.
When maxHotBuckets is exceeded, Splunk Enterprise rolls the least recently used (LRU) hot bucket to warm. Both normal hot buckets and quarantined hot buckets count towards this total. This setting operates independently of maxHotIdleSecs, which can also cause hot buckets to roll. |
| maxHotIdleSecs | Maximum life, in seconds, of a hot bucket. Defaults to 0. A value of 0 turns off the idle check (equivalent to INFINITE idle time).
If a hot bucket exceeds maxHotIdleSecs, Splunk Enterprise rolls it to warm. This setting operates independently of maxHotBuckets, which can also cause hot buckets to roll. |
| maxHotSpanSecs | Upper bound of target maximum timespan of hot/warm buckets in seconds. Defaults to 7776000 seconds (90 days).
Note: If set too small, you can get an explosion of hot/warm buckets in the filesystem. The system sets a lower bound implicitly for this parameter at 3600, but this is an advanced parameter that should be set with care and understanding of the characteristics of your data. |
| maxMemMB | The amount of memory, in MB, allocated for indexing.
This is a global setting, not a per index setting. |
| maxMetaEntries | Sets the maximum number of unique lines in .data files in a bucket, which may help to reduce memory consumption. If set to 0, this setting is ignored (it is treated as infinite).
If exceeded, a hot bucket is rolled to prevent further increase. If your buckets are rolling due to Strings.data hitting this limit, the culprit may be the punct field in your data. If you do not use punct, it may be best to simply disable this (see props.conf.spec in $SPLUNK_HOME/etc/system/README). There is a small time delta between when maximum is exceeded and bucket is rolled. This means a bucket may end up with epsilon more lines than specified, but this is not a major concern unless excess is significant. |
| maxRunningProcessGroups | Maximum number of processes that the indexer fires off at a time.
This is a global setting, not a per index setting. |
| maxTime | ISO8601 formatted timestamp of the newest event time in the index. |
| maxTotalDataSizeMB | The maximum size of an index, in MB. |
| maxWarmDBCount | The maximum number of warm buckets. If this number is exceeded, the warm bucket/s with the lowest value for their latest times are moved to cold. |
| memPoolMB | Determines how much memory is given to the indexer memory pool.
This is a global setting, not a per-index setting. |
| minRawFileSyncSecs | Can be either an integer (or "disable"). Some filesystems are very inefficient at performing sync operations, so only enable this if you are sure it is needed
The integer sets how frequently splunkd forces a filesystem sync while compressing journal slices. During this period, uncompressed slices are left on disk even after they are compressed. Then splunkd forces a filesystem sync of the compressed journal and removes the accumulated uncompressed files. If 0 is specified, splunkd forces a filesystem sync after every slice completes compressing. Specifying "disable" disables syncing entirely: uncompressed slices are removed as soon as compression is complete. |
| minTime | ISO8601 formatted timestamp of the oldest event time in the index. |
| partialServiceMetaPeriod | Related to serviceMetaPeriod. By default it is turned off (zero).
If set, it enables metadata sync every <integer> seconds, but only for records where the sync can be done efficiently in-place, without requiring a full re-write of the metadata file. Records that require full re-write are be sync'ed at serviceMetaPeriod. partialServiceMetaPeriod specifies, in seconds, how frequently it should sync. Zero means that this feature is turned off and serviceMetaPeriod is the only time when metadata sync happens. If the value of partialServiceMetaPeriod is greater than serviceMetaPeriod, this setting has no effect. |
| quarantineFutureSecs | Events with timestamp of quarantineFutureSecs newer than "now" that are dropped into quarantine bucket. Defaults to 2592000 (30 days).
This is a mechanism to prevent main hot buckets from being polluted with fringe events. |
| quarantinePastSecs | Events with timestamp of quarantinePastSecs older than "now" are dropped into quarantine bucket. Defaults to 77760000 (900 days).
This is a mechanism to prevent the main hot buckets from being polluted with fringe events. |
| rawChunkSizeBytes | Target uncompressed size in bytes for individual raw slice in the rawdata journal of the index. Defaults to 131072 (128KB). 0 is not a valid value. If 0 is specified, rawChunkSizeBytes is set to the default value.
Note: rawChunkSizeBytes only specifies a target chunk size. The actual chunk size may be slightly larger by an amount proportional to an individual event size. Warning: This is an advanced parameter. Only change it if instructed to do so by Splunk Support. |
| rotatePeriodInSecs | Rotation period, in seconds, that specifies how frequently to check:
|
| serviceMetaPeriod | Defines how frequently metadata is synced to disk, in seconds. Defaults to 25 (seconds).
You may want to set this to a higher value if the sum of your metadata file sizes is larger than many tens of megabytes, to avoid the hit on I/O in the indexing fast path. |
| summarize | If true, leaves out certain index details, which provides a faster response. |
| suppressBannerList | List of indexes for which we suppress "index missing" warning banner messages.
This is a global setting, not a per index setting. |
| sync | Specifies the number of events that trigger the indexer to sync events.
This is a global setting, not a per index setting. |
| syncMeta | When true, a sync operation is called before file descriptor is closed on metadata file updates. This functionality improves integrity of metadata files, especially in regards to operating system crashes/machine failures.
Note: Do not change this parameter without the input of Splunk Support. |
| thawedPath | An absolute path that contains the thawed (resurrected) databases for the index. |
| thawedPath_expanded | Absolute filepath to the thawed (resurrected) databases. |
| throttleCheckPeriod | Defines how frequently Splunk Enterprise checks for index throttling condition, in seconds. Defaults to 15 (seconds).
Note: Do not change this parameter without the input of Splunk Support. |
| totalEventCount | Total number of events in the index. |
POST data/indexes method detail
Request parameters
| Name | Type | Default | Description |
|---|---|---|---|
| blockSignSize | Number | 0 | Controls how many events make up a block for block signatures.
If this is set to 0, block signing is disabled for this index. A recommended value is 100. |
| bucketRebuildMemoryHint | String | auto | Suggestion for the Splunk Enterprise bucket rebuild process for the size of the time-series (tsidx) file to make.
Caution: This is an advanced parameter. Inappropriate use of this parameter causes splunkd to not start if rebuild is required. Do not set this parameter unless instructed by Splunk Support. Default value,
Values other than "auto" must be 16MB-1GB. Highest legal value (of the numerical part) is 4294967295 You can specify the value using a size suffix: "16777216" or "16MB" are equivalent. |
| coldPath | String | An absolute path that contains the colddbs for the index. The path must be readable and writable. Cold databases are opened as needed when searching. May be defined in terms of a volume definition (see volume section below).
Required. Splunk Enterprise does not start if an index lacks a valid coldPath. | |
| coldToFrozenDir | String | Destination path for the frozen archive. Use as an alternative to a coldToFrozenScript. Splunk Enterprise automatically puts frozen buckets in this directory.
Bucket freezing policy is as follows:
If both coldToFrozenDir and coldToFrozenScript are specified, coldToFrozenDir takes precedence | |
| coldToFrozenScript | String | Path to the archiving script.
If your script requires a program to run it (for example, python), specify the program followed by the path. The script must be in $SPLUNK_HOME/bin or one of its subdirectories. Splunk Enterprise ships with an example archiving script in $SPLUNK_HOME/bin called coldToFrozenExample.py. Splunk DOES NOT recommend using this example script directly. It uses a default path, and if modified in place any changes are overwritten on upgrade. Splunk recommends copying the example script to a new file in bin and modifying it for your system. Most importantly, change the default archive path to an existing directory that fits your needs. If your new script in bin/ is named myColdToFrozen.py, set this key to the following:
By default, the example script has two possible behaviors when archiving:
| |
| compressRawdata | Boolean | true | This parameter is ignored. The splunkd process always compresses raw data. |
| enableOnlineBucketRepair | Boolean | true | Enables asynchronous "online fsck" bucket repair, which runs concurrently with Splunk.
When enabled, you do not have to wait until buckets are repaired to start Splunk. However, you might observe a slight performance degratation. |
| frozenTimePeriodInSecs | Number | 188697600 | Number of seconds after which indexed data rolls to frozen. Defaults to 188697600 (6 years).
Freezing data means it is removed from the index. If you need to archive your data, refer to coldToFrozenDir and coldToFrozenScript parameter documentation. |
| homePath | String | An absolute path that contains the hot and warm buckets for the index.
Required. Splunk Enterprise does not start if an index lacks a valid homePath. CAUTION: Path MUST be readable and writable. | |
| maxBloomBackfillBucketAge | Number | 30d | Valid values are: Integer[m|s|h|d]
If a warm or cold bucket is older than the specified age, do not create or rebuild its bloomfilter. Specify 0 to never rebuild bloomfilters. For example, if a bucket is older than specified with maxBloomBackfillBucketAge, and the rebuilding of its bloomfilter started but did not finish, do not rebuild it. |
| maxConcurrentOptimizes | Number | 6 | The number of concurrent optimize processes that can run against a hot bucket.
This number should be increased if instructed by Splunk Support. Typically the default value should suffice. |
| maxDataSize | Number | auto | The maximum size in MB for a hot DB to reach before a roll to warm is triggered. Specifying "auto" or "auto_high_volume" causes Splunk Enterprise to autotune this parameter (recommended).Use "auto_high_volume" for high volume indexes (such as the main index); otherwise, use "auto". A "high volume index" would typically be considered one that gets over 10GB of data per day.
Although the maximum value you can set this is 1048576 MB, which corresponds to 1 TB, a reasonable number ranges anywhere from 100 - 50000. Any number outside this range should be approved by Splunk Support before proceeding. If you specify an invalid number or string, maxDataSize is auto-tuned. Note: The precise size of your warm buckets may vary from maxDataSize, due to post-processing and timing issues with the rolling policy. |
| maxHotBuckets | Number | 3 | Maximum hot buckets that can exist per index. Defaults to 3.
When maxHotBuckets is exceeded, Splunk Enterprise rolls the least recently used (LRU) hot bucket to warm. Both normal hot buckets and quarantined hot buckets count towards this total. This setting operates independently of maxHotIdleSecs, which can also cause hot buckets to roll. |
| maxHotIdleSecs | Number | 0 | Maximum life, in seconds, of a hot bucket. Defaults to 0.
If a hot bucket exceeds maxHotIdleSecs, Splunk Enterprise rolls it to warm. This setting operates independently of maxHotBuckets, which can also cause hot buckets to roll. A value of 0 turns off the idle check (equivalent to INFINITE idle time). |
| maxHotSpanSecs | Number | 7776000 | Upper bound of target maximum timespan of hot/warm buckets in seconds. Defaults to 7776000 seconds (90 days).
Note:I f you set this too small, you can get an explosion of hot/warm buckets in the filesystem. The system sets a lower bound implicitly for this parameter at 3600, but this is an advanced parameter that should be set with care and understanding of the characteristics of your data. |
| maxMemMB | Number | 5 | The amount of memory, expressed in MB, to allocate for buffering a single tsidx file into memory before flushing to disk. Defaults to 5. The default is recommended for all environments.
IMPORTANT: Calculate this number carefully. Setting this number incorrectly may have adverse effects on your systems memory and/or splunkd stability/performance. |
| maxMetaEntries | Number | 1000000 | Sets the maximum number of unique lines in .data files in a bucket, which may help to reduce memory consumption. If set to 0, this setting is ignored (it is treated as infinite).
If exceeded, a hot bucket is rolled to prevent further increase. If your buckets are rolling due to Strings.data hitting this limit, the culprit may be the There is a small time delta between when maximum is exceeded and bucket is rolled. This means a bucket may end up with epsilon more lines than specified, but this is not a major concern unless excess is significant. |
| maxTimeUnreplicatedNoAcks | Number | 300 | Upper limit, in seconds, on how long an event can sit in raw slice. Applies only if replication is enabled for this index. Otherwise ignored.
If there are any acknowledged events sharing this raw slice, this paramater does not apply. In this case, maxTimeUnreplicatedWithAcks applies. Highest legal value is 2147483647. To disable this parameter, set to 0. Note: this is an advanced parameter. Understand the consequences before changing. |
| maxTimeUnreplicatedWithAcks | Number | 60 | Upper limit, in seconds, on how long events can sit unacknowledged in a raw slice. Applies only if you have enabled acks on forwarders and have replication enabled (with clustering).
Note: This is an advanced parameter. Make sure you understand the settings on all forwarders before changing this. This number should not exceed ack timeout configured on any forwarder, and should actually be set to at most half of the minimum value of that timeout. You can find this setting in outputs.conf readTimeout setting under the tcpout stanza. To disable, set to 0, but this is NOT recommended. Highest legal value is 2147483647. |
| maxTotalDataSizeMB | Number | 500000 | The maximum size of an index (in MB). If an index grows larger than the maximum size, the oldest data is frozen. |
| maxWarmDBCount | Number | 300 | The maximum number of warm buckets. If this number is exceeded, the warm bucket/s with the lowest value for their latest times is moved to cold. |
| minRawFileSyncSecs | Number | disable | Specify an integer (or "disable") for this parameter.
This parameter sets how frequently splunkd forces a filesystem sync while compressing journal slices. During this period, uncompressed slices are left on disk even after they are compressed.

Caution: Do not set this value, except under advice from Splunk Support. |
| name required |
String | The name of the index to create. | |
| partialServiceMetaPeriod | Number | 0 | Related to serviceMetaPeriod. If set, it enables metadata sync every <integer> seconds, but only for records where the sync can be done efficiently in-place, without requiring a full re-write of the metadata file. Records that require full re-write are be sync'ed at serviceMetaPeriod.
If the value of partialServiceMetaPeriod is greater than serviceMetaPeriod, this setting has no effect. By default it is turned off (zero). |
| processTrackerServiceInterval | Number | 1 | Specifies, in seconds, how often the indexer checks the status of the child OS processes it launched to see if it can launch new processes for queued requests. Defaults to 15.
If set to 0, the indexer checks child process status every second. Highest legal value is 4294967295. |
| quarantineFutureSecs | Number | 2592000 | Events with timestamp of quarantineFutureSecs newer than "now" are dropped into quarantine bucket. Defaults to 2592000 (30 days).
This is a mechanism to prevent main hot buckets from being polluted with fringe events. |
| quarantinePastSecs | Number | 77760000 | Events with timestamp of quarantinePastSecs older than "now" are dropped into quarantine bucket. Defaults to 77760000 (900 days).

| repFactor | String | 0 | Index replication control. This parameter applies to only Splunk Enterprise clustering slaves.
|
| rotatePeriodInSecs | Number | 60 | How frequently (in seconds) to check if a new hot bucket needs to be created. Also, how frequently to check if there are any warm/cold buckets that should be rolled/frozen. |
| serviceMetaPeriod | Number | 25 | Defines how frequently metadata is synced to disk, in seconds. Defaults to 25 (seconds).
You may want to set this to a higher value if the sum of your metadata file sizes is larger than many tens of megabytes, to avoid the hit on I/O in the indexing fast path. |
| syncMeta | Boolean | true | When true, a sync operation is called before file descriptor is closed on metadata file updates. This functionality improves integrity of metadata files, especially in regards to operating system crashes/machine failures.

| maxWarmDBCount | The maximum number of warm buckets. If this number is exceeded, the warm bucket/s with the lowest value for their latest times are moved to cold. |
| memPoolMB | Determines how much memory is given to the indexer memory pool.
This is a global setting, not a per-index setting. |
| minRawFileSyncSecs | Can be either an integer (or "disable"). Some filesystems are very inefficient at performing sync operations, so only enable this if you are sure it is needed
The integer sets how frequently splunkd forces a filesystem sync while compressing journal slices. During this period, uncompressed slices are left on disk even after they are compressed. Then splunkd forces a filesystem sync of the compressed journal and removes the accumulated uncompressed files. If 0 is specified, splunkd forces a filesystem sync after every slice completes compressing. Specifying "disable" disables syncing entirely: uncompressed slices are removed as soon as compression is complete. |
| minStreamGroupQueueSize | Minimum size of the queue that stores events in memory before committing them to a tsidx file. |
| minTime | ISO8601 timestamp of the oldest event time in the index. |
| partialServiceMetaPeriod | Related to serviceMetaPeriod. By default it is turned off (zero).
If set, it enables metadata sync every <integer> seconds, but only for records where the sync can be done efficiently in-place, without requiring a full re-write of the metadata file. Records that require full re-write are be sync'ed at serviceMetaPeriod. partialServiceMetaPeriod specifies, in seconds, how frequently it should sync. Zero means that this feature is turned off and serviceMetaPeriod is the only time when metadata sync happens. If the value of partialServiceMetaPeriod is greater than serviceMetaPeriod, this setting has no effect. |
| processTrackerServiceInterval | How often, in seconds, the indexer checks the status of the child OS processes it launched to see if it can launch new processes for queued requests. |
| quarantineFutureSecs | Events with timestamp of quarantineFutureSecs newer than "now" are dropped into quarantine bucket. Defaults to 2592000 (30 days).
This is a mechanism to prevent main hot buckets from being polluted with fringe events. |
| quarantinePastSecs | Events with timestamp of quarantinePastSecs older than "now" are dropped into quarantine bucket. Defaults to 77760000 (900 days).
This is a mechanism to prevent the main hot buckets from being polluted with fringe events. |
| rawChunkSizeBytes | Target uncompressed size in bytes for individual raw slice in the rawdata journal of the index. Defaults to 131072 (128KB). 0 is not a valid value. If 0 is specified, rawChunkSizeBytes is set to the default value.
Note: rawChunkSizeBytes only specifies a target chunk size. The actual chunk size may be slightly larger by an amount proportional to an individual event size. Warning: This is an advanced parameter. Only change it if instructed to do so by Splunk Support. |
| repFactor | Index replication control. This parameter applies to only Splunk Enterprise clustering slaves.
|
| rotatePeriodInSecs | Rotation period, in seconds, that specifies how frequently to check:
|
| serviceMetaPeriod | Defines how frequently metadata is synced to disk, in seconds. Defaults to 25 (seconds).
You may want to set this to a higher value if the sum of your metadata file sizes is larger than many tens of megabytes, to avoid the hit on I/O in the indexing fast path. |
| suppressBannerList | List of indexes for which we suppress "index missing" warning banner messages.
This is a global setting, not a per index setting. |
| sync | Specifies the number of events that trigger the indexer to sync events.
This is a global setting, not a per index setting. |
| syncMeta | When true, a sync operation is called before file descriptor is closed on metadata file updates. This functionality improves integrity of metadata files, especially in regards to operating system crashes/machine failures.
Note: Do not change this parameter without the input of Splunk Support. |
| thawedPath | Filepath to the thawed (resurrected) databases for the index. |
| thawedPath_expanded | Absolute filepath to the thawed (resurrected) databases. |
| throttleCheckPeriod | Defines how frequently Splunk Enterprise checks for index throttling condition, in seconds. Defaults to 15 (seconds).
Note: Do not change this parameter without the input of Splunk Support. |
| totalEventCount | Total number of events in the index. |
| tstatsHomePath | Location where datamodel acceleration TSIDX data for this index is stored. |
| warmToColdScript | Script to run when moving data from warm to cold. See input parameter description for details. |

DELETE data/indexes/{name} method detail
Request parameters
None
Response data keys
None
Application usage
Before executing this operation, look through all inputs.conf files (on your indexer and on any forwarders sending data to the indexer) and make sure that none of the stanzas are directing data to the index you plan to delete.
In other words, if you want to delete an index called "nogood," make sure the attribute/value pair index=nogood does not appear in any input stanzas. Once the index is deleted, Splunk Enterprise discards any data sent to that index.
For information on deleting indexes and deleting data from indexes, refer to Remove data from Splunk Enterprise in the Splunk Managing Indexers and Clusters manual.
The method returns HTTP status code = 409, if {name} was disabled but Splunk Enterprise was not restarted. Restart Splunk Enterprise and try again.

| Name | Type | Default | Description |
|---|---|---|---|
| summarize | Boolean | false |
[Optional] Response type:
|
Response data keys
| Name | Description |
|---|---|
| assureUTF8 | Indicates whether all data retreived from the index is proper UTF8. If enabled (set to True), degrades indexing performance.
This is a global setting, not a per index setting. |
| blockSignSize | Controls how many events make up a block for block signatures.
If this is set to 0, block signing is disabled for this index. A recommended value is 100. |
| blockSignatureDatabase | The index that stores block signatures of events.
This is a global setting, not a per index setting. |
| bloomfilterTotalSizeKB | Total size of all bloom filter files, in KB. |
| coldPath | Filepath to the cold databases for the index. |
| coldPath_expanded | Absoute filepath to the cold databases. |
| coldToFrozenDir | Destination path for the frozen archive. Used as an alternative to a coldToFrozenScript. Splunk Enterprise automatically puts frozen buckets in this directory.
Bucket freezing policy is as follows:
If both coldToFrozenDir and coldToFrozenScript are specified, coldToFrozenDir takes precedence. |
| coldToFrozenScript | Path to the archiving script.
See the POST parameter description for details. |
| compressRawdata | This value is ignored. splunkd process always compresses raw data. |
| currentDBSizeMB | Total size, in MB, of data stored in the index. The total incudes data in the home, cold and thawed paths. |
| defaultDatabase | If no index destination information is available in the input data, the index shown here is the destination of such data. |
| disabled | Indicates if the index is disabled. |
| enableRealtimeSearch | Indicates if this is a real-time search.
This is a global setting, not a per index setting. |
| frozenTimePeriodInSecs | Number of seconds after which indexed data rolls to frozen. Defaults to 188697600 (6 years).
Freezing data means it is removed from the index. If you need to archive your data, refer to coldToFrozenDir and coldToFrozenScript parameter documentation. |
| homePath | An absolute path that contains the hot and warm buckets for the index. |
| homePath_expanded | An absolute filepath to the hot and warm buckets for the index. |
| indexThreads | Number of threads used for indexing.
This is a global setting, not a per index setting. |
| isInternal | Indicates if this is an internal index (for example, _internal, _audit). |
| lastInitTime | Last time the index processor was successfully initialized.
This is a global setting, not a per index setting. |
| maxConcurrentOptimizes | The number of concurrent optimize processes that can run against a hot bucket.
This number should be increased if instructed by Splunk Support. Typically the default value should suffice. |
| maxDataSize | The maximum size in MB for a hot DB to reach before a roll to warm is triggered. Specifying "auto" or "auto_high_volume" causes Splunk Enterprise to autotune this parameter (recommended). Use "auto_high_volume" for high volume indexes (such as the main index); otherwise, use "auto". A "high volume index" is typically one that gets over 10GB of data per day.
Although the maximum value you can set this is 1048576 MB, which corresponds to 1 TB, a reasonable number ranges anywhere from 100 - 50000. Any number outside this range should be approved by Splunk Support before proceeding. If you specify an invalid number or string, maxDataSize is auto-tuned. Note: The precise size of your warm buckets may vary from maxDataSize, due to post-processing and timing issues with the rolling policy. |
| maxHotBuckets | Maximum hot buckets that can exist per index. Defaults to 3.
When maxHotBuckets is exceeded, Splunk Enterprise rolls the least recently used (LRU) hot bucket to warm. Both normal hot buckets and quarantined hot buckets count towards this total. This setting operates independently of maxHotIdleSecs, which can also cause hot buckets to roll. |
| maxHotIdleSecs | Maximum life, in seconds, of a hot bucket. Defaults to 0. A value of 0 turns off the idle check (equivalent to INFINITE idle time).
If a hot bucket exceeds maxHotIdleSecs, Splunk Enterprise rolls it to warm. This setting operates independently of maxHotBuckets, which can also cause hot buckets to roll. |
| maxHotSpanSecs | Upper bound of target maximum timespan of hot/warm buckets in seconds. Defaults to 7776000 seconds (90 days).
Note: If set too small, you can get an explosion of hot/warm buckets in the filesystem. The system sets a lower bound implicitly for this parameter at 3600, but this is an advanced parameter that should be set with care and understanding of the characteristics of your data. |
| maxMemMB | The amount of memory, in MB, allocated for indexing.
This is a global setting, not a per index setting. |
| maxMetaEntries | Sets the maximum number of unique lines in .data files in a bucket, which may help to reduce memory consumption. If set to 0, this setting is ignored (it is treated as infinite).
If exceeded, a hot bucket is rolled to prevent further increase. If your buckets are rolling due to Strings.data hitting this limit, the culprit may be the punct field in your data. If you do not use punct, it may be best to simply disable this (see props.conf.spec in $SPLUNK_HOME/etc/system/README). There is a small time delta between when maximum is exceeded and bucket is rolled. This means a bucket may end up with epsilon more lines than specified, but this is not a major concern unless excess is significant. |
| maxRunningProcessGroups | Maximum number of processes that the indexer fires off at a time.
This is a global setting, not a per index setting. |
| maxTime | Timestamp of the newest event time in the index. |
| maxTotalDataSizeMB | The maximum size of an index, in MB. |
| maxWarmDBCount | Maximum number of warm buckets. |
| memPoolMB | Determines how much memory is given to the indexer memory pool.
This is a global setting, not a per-index setting. |

| minTime | Timestamp of the oldest event time in the index. |
| numBloomfilters | The number of bloom filters created for this index. |
| numHotBuckets | The number of hot buckets created for this index. |
| numWarmBuckets | The number of warm buckets created for this index. |
| partialServiceMetaPeriod | Related to serviceMetaPeriod. By default it is turned off (zero).

You may want to set this to a higher value if the sum of your metadata file sizes is larger than many tens of megabytes, to avoid the hit on I/O in the indexing fast path. |
| summarize | If true, leaves out certain index details, which provides a faster response. |
| suppressBannerList | List of indexes for which we suppress "index missing" warning banner messages.
This is a global setting, not a per index setting. |
| sync | Specifies the number of events that trigger the indexer to sync events.

POST data/indexes/{name} method detail
Request parameters
| Name | Type | Default | Description |
|---|---|---|---|
| blockSignSize | Number | 0 | Controls how many events make up a block for block signatures.
If this is set to 0, block signing is disabled for this index. A recommended value is 100. |
| bucketRebuildMemoryHint | String | auto | Suggestion for the Splunk Enterprise bucket rebuild process for the size of the time-series (tsidx) file to make.
Caution: This is an advanced parameter. Inappropriate use of this parameter causes splunkd to not start if rebuild is required. Do not set this parameter unless instructed by Splunk Support. Default value,
Values other than "auto" must be 16MB-1GB. Highest legal value (of the numerical part) is 4294967295 You can specify the value using a size suffix: "16777216" or "16MB" are equivalent. |
| coldToFrozenDir | String | Destination path for the frozen archive. Use as an alternative to a coldToFrozenScript. Splunk Enterprise automatically puts frozen buckets in this directory.
Bucket freezing policy is as follows:
If both coldToFrozenDir and coldToFrozenScript are specified, coldToFrozenDir takes precedence | |
| coldToFrozenScript | String | Path to the archiving script.
If your script requires a program to run it (for example, python), specify the program followed by the path. The script must be in $SPLUNK_HOME/bin or one of its subdirectories. Splunk Enterprise ships with an example archiving script in $SPLUNK_HOME/bin called coldToFrozenExample.py. Splunk DOES NOT recommend using this example script directly. It uses a default path, and if modified in place any changes are overwritten on upgrade. Splunk recommends copying the example script to a new file in bin and modifying it for your system. Most importantly, change the default archive path to an existing directory that fits your needs. If your new script in bin/ is named myColdToFrozen.py, set this key to the following:
By default, the example script has two possible behaviors when archiving:
| |
| compressRawdata | Boolean | true | This parameter is ignored. The splunkd process always compresses raw data. |
| enableOnlineBucketRepair | Boolean | true | Enables asynchronous "online fsck" bucket repair, which runs concurrently with Splunk.
When enabled, you do not have to wait until buckets are repaired to start Splunk. However, you might observe a slight performance degratation. |
| frozenTimePeriodInSecs | Number | 188697600 | Number of seconds after which indexed data rolls to frozen. Defaults to 188697600 (6 years).
Freezing data means it is removed from the index. If you need to archive your data, refer to coldToFrozenDir and coldToFrozenScript parameter documentation. |
| maxBloomBackfillBucketAge | Number | 30d | Valid values are: Integer[m|s|h|d]
If a warm or cold bucket is older than the specified age, do not create or rebuild its bloomfilter. Specify 0 to never rebuild bloomfilters. For example, if a bucket is older than specified with maxBloomBackfillBucketAge, and the rebuilding of its bloomfilter started but did not finish, do not rebuild it. |
| maxConcurrentOptimizes | Number | 6 | The number of concurrent optimize processes that can run against a hot bucket.
This number should be increased if instructed by Splunk Support. Typically the default value should suffice. |
| maxDataSize | Number | auto | The maximum size in MB for a hot DB to reach before a roll to warm is triggered. Specifying "auto" or "auto_high_volume" causes Splunk Enterprise to autotune this parameter (recommended).Use "auto_high_volume" for high volume indexes (such as the main index); otherwise, use "auto". A "high volume index" would typically be considered one that gets over 10GB of data per day.
Although the maximum value you can set this is 1048576 MB, which corresponds to 1 TB, a reasonable number ranges anywhere from 100 - 50000. Any number outside this range should be approved by Splunk Support before proceeding. If you specify an invalid number or string, maxDataSize is auto-tuned. Note: The precise size of your warm buckets may vary from maxDataSize, due to post-processing and timing issues with the rolling policy. |
| maxHotBuckets | Number | 3 | Maximum hot buckets that can exist per index. Defaults to 3.

| maxHotSpanSecs | Number | 7776000 | Upper bound of target maximum timespan of hot/warm buckets in seconds. Defaults to 7776000 seconds (90 days).
Note:I f you set this too small, you can get an explosion of hot/warm buckets in the filesystem. The system sets a lower bound implicitly for this parameter at 3600, but this is an advanced parameter that should be set with care and understanding of the characteristics of your data. |
| maxMemMB | Number | 5 | The amount of memory, expressed in MB, to allocate for buffering a single tsidx file into memory before flushing to disk. Defaults to 5. The default is recommended for all environments.
IMPORTANT: Calculate this number carefully. Setting this number incorrectly may have adverse effects on your systems memory and/or splunkd stability/performance. |
| maxMetaEntries | Number | 1000000 | Sets the maximum number of unique lines in .data files in a bucket, which may help to reduce memory consumption. If set to 0, this setting is ignored (it is treated as infinite).
If exceeded, a hot bucket is rolled to prevent further increase. If your buckets are rolling due to Strings.data hitting this limit, the culprit may be the There is a small time delta between when maximum is exceeded and bucket is rolled. This means a bucket may end up with epsilon more lines than specified, but this is not a major concern unless excess is significant. |
| maxTimeUnreplicatedNoAcks | Number | 300 | Upper limit, in seconds, on how long an event can sit in raw slice. Applies only if replication is enabled for this index. Otherwise ignored.
If there are any acknowledged events sharing this raw slice, this paramater does not apply. In this case, maxTimeUnreplicatedWithAcks applies. Highest legal value is 2147483647. To disable this parameter, set to 0. Note: this is an advanced parameter. Understand the consequences before changing. |
| maxTimeUnreplicatedWithAcks | Number | 60 | Upper limit, in seconds, on how long events can sit unacknowledged in a raw slice. Applies only if you have enabled acks on forwarders and have replication enabled (with clustering).
Note: This is an advanced parameter. Make sure you understand the settings on all forwarders before changing this. This number should not exceed ack timeout configured on any forwarder, and should actually be set to at most half of the minimum value of that timeout. You can find this setting in outputs.conf readTimeout setting under the tcpout stanza. To disable, set to 0, but this is NOT recommended. Highest legal value is 2147483647. |
| maxTotalDataSizeMB | Number | 500000 | The maximum size of an index (in MB). If an index grows larger than the maximum size, the oldest data is frozen. |
| maxWarmDBCount | Number | 300 | The maximum number of warm buckets. If this number is exceeded, the warm bucket/s with the lowest value for their latest times are moved to cold. |
| minRawFileSyncSecs | Number | disable | Specify an integer (or "disable") for this parameter.

Caution: Do not set this value, except under advice from Splunk Support. |
| partialServiceMetaPeriod | Number | 0 | Related to serviceMetaPeriod. If set, it enables metadata sync every <integer> seconds, but only for records where the sync can be done efficiently in-place, without requiring a full re-write of the metadata file. Records that require full re-write are be sync'ed at serviceMetaPeriod.
If the value of partialServiceMetaPeriod is greater than serviceMetaPeriod, this setting has no effect. By default it is turned off (zero). |
| processTrackerServiceInterval | Number | 1 | Specifies, in seconds, how often the indexer checks the status of the child OS processes it launched to see if it can launch new processes for queued requests. Defaults to 15.
If set to 0, the indexer checks child process status every second. Highest legal value is 4294967295. |
| quarantineFutureSecs | Number | 2592000 | Events with timestamp of quarantineFutureSecs newer than "now" are dropped into quarantine bucket. Defaults to 2592000 (30 days).
This is a mechanism to prevent main hot buckets from being polluted with fringe events. |
| quarantinePastSecs | Number | 77760000 | Events with timestamp of quarantinePastSecs older than "now" are dropped into quarantine bucket. Defaults to 77760000 (900 days).

| serviceMetaPeriod | Number | 25 | Defines how frequently metadata is synced to disk, in seconds. Defaults to 25 (seconds).
You may want to set this to a higher value if the sum of your metadata file sizes is larger than many tens of megabytes, to avoid the hit on I/O in the indexing fast path. |
| syncMeta | Boolean | true | When true, a sync operation is called before file descriptor is closed on metadata file updates. This functionality improves integrity of metadata files, especially in regards to operating system crashes/machine failures.
Note: Do not change this parameter without the input of a Splunk Support. |
| throttleCheckPeriod | Number | 15 | Defines how frequently Splunk Enterprise checks for index throttling condition, in seconds. Defaults to 15 (seconds).
Note: Do not change this parameter without the input of Splunk Support. |
| tstatsHomePath | String | Location to store datamodel acceleration TSIDX data for this index. Restart splunkd after changing this parameter.
If specified, it must be defined in terms of a volume definition. Caution: Path must be writable. Default value: volume:_splunk_summaries/$_index_name/tstats | |
| warmToColdScript | String | Path to a script to run when moving data from warm to cold.

If a hot bucket exceeds maxHotIdleSecs, Splunk Enterprise rolls it to warm. This setting operates independently of maxHotBuckets, which can also cause hot buckets to roll. |
| maxHotSpanSecs | Upper bound of target maximum timespan of hot/warm buckets in seconds. Defaults to 7776000 seconds (90 days).
Note: If set too small, you can get an explosion of hot/warm buckets in the filesystem. The system sets a lower bound implicitly for this parameter at 3600, but this is an advanced parameter that should be set with care and understanding of the characteristics of your data. |
| maxMemMB | The amount of memory, in MB, allocated for indexing.
This is a global setting, not a per index setting. |
| maxMetaEntries | Sets the maximum number of unique lines in .data files in a bucket, which may help to reduce memory consumption. If set to 0, this setting is ignored (it is treated as infinite).
If exceeded, a hot bucket is rolled to prevent further increase. If your buckets are rolling due to Strings.data hitting this limit, the culprit may be the punct field in your data. If you do not use punct, it may be best to simply disable this (see props.conf.spec in $SPLUNK_HOME/etc/system/README). There is a small time delta between when maximum is exceeded and bucket is rolled. This means a bucket may end up with epsilon more lines than specified, but this is not a major concern unless excess is significant. |
| maxTime | Timestamp of the newest event time in the index. |
| maxTimeUnreplicatedNoAcks | Upper limit, in seconds, on how long an event can sit in raw slice. Applies only if replication is enabled for this index. Otherwise ignored.
If there are any acknowledged events sharing this raw slice, this paramater does not apply. In this case, maxTimeUnreplicatedWithAcks applies. Highest legal value is 2147483647. To disable this parameter, set to 0. Note: this is an advanced parameter. Understand the consequences before changing. |
| maxTimeUnreplicatedWithAcks | Upper limit, in seconds, on how long events can sit unacknowledged in a raw slice. Applies only if you have enabled acks on forwarders and have replication enabled (with clustering).
Note: This is an advanced parameter. Make sure you understand the settings on all forwarders before changing this. This number should not exceed ack timeout configured on any forwarder, and should actually be set to at most half of the minimum value of that timeout. You can find this setting in outputs.conf readTimeout setting under the tcpout stanza. To disable, set to 0, but this is NOT recommended. Highest legal value is 2147483647. |
| maxTotalDataSizeMB | The maximum size of an index, in MB. |
| maxWarmDBCount | The maximum number of warm buckets. If this number is exceeded, the warm bucket/s with the lowest value for their latest times are moved to cold. |
| memPoolMB | Determines how much memory is given to the indexer memory pool.
This is a global setting, not a per-index setting. |
| minRawFileSyncSecs | Can be either an integer (or "disable"). Some filesystems are very inefficient at performing sync operations, so only enable this if you are sure it is needed
The integer sets how frequently splunkd forces a filesystem sync while compressing journal slices. During this period, uncompressed slices are left on disk even after they are compressed. Then splunkd forces a filesystem sync of the compressed journal and removes the accumulated uncompressed files. If 0 is specified, splunkd forces a filesystem sync after every slice completes compressing. Specifying "disable" disables syncing entirely: uncompressed slices are removed as soon as compression is complete. |
| minStreamGroupQueueSize | Minimum size of the queue that stores events in memory before committing them to a tsidx file. |
| minTime | Timestamp of the oldest event time in the index. |
| partialServiceMetaPeriod | Related to serviceMetaPeriod. By default it is turned off (zero).
If set, it enables metadata sync every <integer> seconds, but only for records where the sync can be done efficiently in-place, without requiring a full re-write of the metadata file. Records that require full re-write are be sync'ed at serviceMetaPeriod. partialServiceMetaPeriod specifies, in seconds, how frequently it should sync. Zero means that this feature is turned off and serviceMetaPeriod is the only time when metadata sync happens. If the value of partialServiceMetaPeriod is greater than serviceMetaPeriod, this setting has no effect. |
| processTrackerServiceInterval | How often, in seconds, the indexer checks the status of the child OS processes it launched to see if it can launch new processes for queued requests. |
| quarantineFutureSecs | Events with timestamp of quarantineFutureSecs newer than "now" are dropped into quarantine bucket. Defaults to 2592000 (30 days).
This is a mechanism to prevent main hot buckets from being polluted with fringe events. |
| quarantinePastSecs | Events with timestamp of quarantinePastSecs older than "now" are dropped into quarantine bucket. Defaults to 77760000 (900 days).
This is a mechanism to prevent the main hot buckets from being polluted with fringe events. |
| rawChunkSizeBytes | Target uncompressed size in bytes for individual raw slice in the rawdata journal of the index. Defaults to 131072 (128KB). 0 is not a valid value. If 0 is specified, rawChunkSizeBytes is set to the default value.
Note: rawChunkSizeBytes only specifies a target chunk size. The actual chunk size may be slightly larger by an amount proportional to an individual event size. Warning: This is an advanced parameter. Only change it if instructed to do so by Splunk Support. |
| repFactor | Index replication control. This parameter applies to only Splunk Enterprise clustering slaves.
|
| rotatePeriodInSecs | Rotation period, in seconds, that specifies how frequently to check:
|
| serviceMetaPeriod | Defines how frequently metadata is synced to disk, in seconds. Defaults to 25 (seconds).
You may want to set this to a higher value if the sum of your metadata file sizes is larger than many tens of megabytes, to avoid the hit on I/O in the indexing fast path. |
| suppressBannerList | List of indexes for which we suppress "index missing" warning banner messages.
This is a global setting, not a per index setting. |
| sync | Specifies the number of events that trigger the indexer to sync events.
This is a global setting, not a per index setting. |
| syncMeta | When true, a sync operation is called before file descriptor is closed on metadata file updates. This functionality improves integrity of metadata files, especially in regards to operating system crashes/machine failures.
Note: Do not change this parameter without the input of Splunk Support. |
| thawedPath | Filepath to the thawed (resurrected) databases for the index. |
| thawedPath_expanded | Absolute filepath to the thawed (resurrected) databases. |
| throttleCheckPeriod | Defines how frequently Splunk Enterprise checks for index throttling condition, in seconds. Defaults to 15 (seconds).
Note: Do not change this parameter without the input of Splunk Support. |
| totalEventCount | Total number of events in the index. |
| tstatsHomePath | Location where datamodel acceleration TSIDX data for this index is stored. |
| warmToColdScript | Script to run when moving data from warm to cold. See input parameter description for details. |

Description
Access host-level, dynamic CPU utilization and paging information.
Note: At least one observation period must pass after Splunk Enterprise startup for valid endpoint data to be available. The observation period is defined in the $SPLUNK_HOME/etc/system/default/server.conf file:
[introspection:generator:resource_usage] collectionPeriodInSecs = 600
The default period is 10 seconds, but 10 minutes (600 seconds) on a Universal Forwarder.

Response data keys
| Name | Description |
|---|---|
| cpu_idle_pct | Percentage of time CPU is idle. Value reported as 100.0 on Windows except for Vista+ and XP/Win2003 English-only OSes. |
| cpu_system_pct | Percentage of time CPU is running in system mode. Missing from Windows except for Vista+ and XP/Win2003 English-only OSes. |
| cpu_user_pct | Percentage of time CPU is running in user mode. Missing from Windows except for Vista+ and XP/Win2003 English-only OSes. |
| forks | Cumulative number of forked processes since OS startup. Not available on Windows. |
| mem | Total physical memory installed (MB). |
| mem_used | Total physical memory used (MB). The amount of actual physical memory minus the amount of physical memory currently available. This is the amount of physical memory that can be immediately reused without having to first write its contents to disk. On Unix, mem_used = total_phys_ram - (free_mem + buffer_mem + cached_mem) On Windows, mem_used = (memoryStatus.ullTotalPhys - memoryStatus.ullAvailPhys); See GlobalMemoryStatusEx function |
| normalized_load_avg_1min | Normalized load average of runnable_process_count across all cores (cumulative_load_avg / number_of_cores). This value is not reliable for a VM guest. |
| pg_paged_out | Cumulative VM page count paged since OS startup. Not available on Windows. |
| pg_swapped_out | Cumulative pages swapped out since OS startup. Not available on Windows. |
| runnable_process_count | Number of process running or in the runnable queue. Value reported as 1 on Windows except for Vista+ and XP/Win2003 English-only OSes. |
| swap | Amount of disk allocated to swap (fractional MB). |
| swap_used | Swap space currently in use (fractional MB). |

https://<host>:<mPort>/services/server/status/resource-usage/splunk-processes
Description
Access operating system resource utilization information.
Note: At least one observation period must pass after Splunk Enterprise startup for valid endpoint data to be available. The observation period is defined in the $SPLUNK_HOME/etc/system/default/server.conf file:
[introspection:generator:resource_usage] collectionPeriodInSecs = 600
The default period is 10 seconds, but 10 minutes (600 seconds) on a Universal Forwarder.

Response data keys
| Name | Description | ||||||||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| args | Non-search process arguments. | ||||||||||||||||||
| cpu_system_time | Cumulative time this process has spent executing in kernel (incl. system calls). Extra field. | ||||||||||||||||||
| cpu_user_time | Cumulative time this process has spent executing in user space (incl. library functions). Extra field. | ||||||||||||||||||
| elapsed | Elapsed wall time, accurate to within the collection period. | ||||||||||||||||||
| fd_used | Number of currently open files used by this process. | ||||||||||||||||||
| mem_unshared_data_used | Amount of heap and stack used. Not available on Windows. Extra field. | ||||||||||||||||||
| mem_used | Current amount of resident physical memory used (MB). (Usually far less deceiving than virtual memory because operating systems can be liberal with virtual memory size but never with resident memory size.) On Windows, mem_used is obtained by reading the WorkingSetSize property returned by the GetProcessMemoryInfo() function (see GetProcessMemoryInfo function and PROCESS_MEMORY_COUNTERS structure). | ||||||||||||||||||
| normalized_pct_cpu | Percentage of CPU usage across all cores. 100% is equivalent to all CPU resources on the machine.
| ||||||||||||||||||
| page_faults | Number of major page faults. Extra field. | ||||||||||||||||||
| pct_cpu | Percentage of CPU usage, relative to one core. 100% is equivalent to 1 core.
| ||||||||||||||||||
| pct_memory | Percentage of physical memory used hostwide ((mem_used/available_host_memory) * 100). | ||||||||||||||||||
| pid | Process ID. | ||||||||||||||||||
| ppid | Parent process ID. Not available for all processes. | ||||||||||||||||||
| process | Process name. The .exe suffix is stripped on Windows operating systems.
| ||||||||||||||||||
| read_mb | Amount of data read (MB), excluding cache reads. | ||||||||||||||||||
| search_props | Search properties map of the following key:value pairs:
| ||||||||||||||||||
| status | Status from the OS scheduler. Can be R (runnable or running), W (waiting), stopped, Z (zombie), or O (other). W includes voluntary sleep or blocking on I/O. O means status is knowable but does not fit into one of those categories. Not available on Windows. | ||||||||||||||||||
| t_count | Current number of threads. | ||||||||||||||||||
| written_mb | Amount of data written (MB), excluding canceled writes. |
