Adds the results of a search to a summary index that you specify. You must create the summary index before you invoke the
collect index=<string> [<arg-options>...]
- Syntax: index=<string>
- Description: Name of the summary index where the events are added. The index must exist before the events are added. The index is not created automatically.
- Syntax: addtime=<bool> | file=<string> | spool=<bool> | marker=<string> | testmode=<bool> | run_in_preview=<bool> | host=<string> | source=<string> | sourcetype=<string>
- Description: Optional arguments for the collect command. See the arg-options section for the descriptions for each option.
- Syntax: addtime=<bool>
- Description: Use this option to specify whether to prefix a time field on to each event. Some commands return results that do not have a
_rawfield, such as the stats, chart, timechart commands. If you specify
addtime=false, the Splunk software uses its generic date detection against fields in whatever order they happen to be in the summary rows. If you specify
addtime=true, the Splunk software uses the search time range
info_min_time. This time range is added by the sistats) command or
_time. Splunk software adds the time field based on the first field that it finds:
- Default: true
- Syntax: file=<string>
- Description: The file name where you want the events to be written. You can use a timestamp or a random number for the file name by specifying either file=$timestamp$ or file=$random$.
- Usage: ".stash" needs to be added at the end of the file name when used with "index=". Otherwise, the data is added to the main index.
- Default: <random-number>_events.stash
- Syntax: host=<string>
- Description: The name of the host that you want to specify for the events.
- Syntax: marker=<string>
- Description: A string, usually of key-value pairs, to append to each event written out. Each key-value pair must be separated by a comma and a space.
- If the value contains spaces or commas, it must be escape quoted. For example if the key-value pair is
search_name=vpn starts and stops, you must change it to
search_name=\"vpn starts and stops\".
- Syntax: run_in_preview=<bool>
- Description: Controls whether the
collectcommand is enabled during preview generation. Generally, you do not want to insert preview results into the summary index, run-in-preview=false. In some cases, such as when a custom search command is used as part of the search, you might want to turn this on to ensure correct summary indexable previews are generated.
- Default: false
- Syntax: spool=<bool>
- Description: If set to true, the summary indexing file is written to the Splunk spool directory, where it is indexed automatically. If set to false, the file is written to the
$SPLUNK_HOME/var/run/splunkdirectory. The file remains in this directory unless some form of further automation or administration is done. If you have Splunk Enterprise, you can use this command to troubleshoot summary indexing by dumping the output file to a location on disk where it will not be ingested as data.
- Default: true
- Syntax: source=<string>
- Description: The name of the source that you want to specify for the events.
- Syntax: sourcetype=<string>
- Description: The name of the source type that you want to specify for the events. By specifying a sourcetype outside of stash, you will incur license usage.
- Default: stash
- Syntax: testmode=<bool>
- Description: Toggle between testing and real mode. In testing mode the results are not written into the new index but the search results are modified to appear as they would if sent to the index.
- Default: false
The events are written to a file whose name format is: random-num_events.stash, unless overwritten, in a directory that your Splunk deployment is monitoring. If the events contain a
_raw field, then this field is saved. If the events do not have a
_raw field, one is created by concatenating all the fields into a comma-separated list of key=value pairs.
collect command also works with real-time searches that have a time range of All time.
Events without timestamps
If you apply the
collect command to events that do not have timestamps, the command designates a time for all of the events using the earliest (or minimum) time of the search range. For example, if you use the
collect command over the past four hours (range: -4h to +0h), the command assigns a timestamp that is four hours prior to the time that the search was launched. The timestamp is applied to all of the events without a timestamp.
If you use the
collect command with a time range of All time and the events do not have timestamps, the current system time is used for the timestamps.
For more information on summary indexing of data without timestamps, see "Use summary indexing for increased reporting efficiency" in the Knowledge Manager Manual.
Moving events to a different index
You can use the
collect command to move selected file content from one index to another index.
Construct a search that returns the data you want to port, and pipe the results to the
collect command. For example:
index=whatever host=whatever source=whatever whatever | collect index=foo
This search ports the data into the
foo index. The sourcetype is changed to
You can specify a sourcetype with the
collect command. However, specifying a sourcetype counts against your license, as if you indexed the data again.
1. Put "download" events into an index named "download count"
eventtypetag="download" | collect index=downloadcount
2. Collect statistics on VPN connects and disconnects
You want to collect hourly statistics on VPN connects and disconnects by country.
| geoip REMOTE_IP
| eval country_source=if(REMOTE_IP_country_code="US","domestic","foreign")
| bin _time span=1h
| stats count by _time,vpn_action,country_source
| collect index=mysummary marker="summary_type=vpn, summary_span=3600,
summary_method=bin, search_name=\"vpn starts and stops\""
addinfo command ensures that the search results contain fields that specify when the search was run to populate these particular index values.
