Splunk® Enterprise

REST API Reference Manual

Splunk Enterprise version 8.2 is no longer supported as of September 30, 2023. See the Splunk Software Support Policy for details. For information about upgrading to a supported version, see How to upgrade Splunk Enterprise.

KV store endpoint descriptions

This introduction describes syntax common to all app KV Store REST endpoints. For more information about the KV Store, see App Key Value Store on the Splunk developer portal.

REST API usage details

Review ACL information for an endpoint

To check Access Control List (ACL) properties for an endpoint, append /acl to the path. For more information see Access Control List in the REST API User Manual.

Authentication and Authorization

Username and password authentication is required for access to endpoints and REST operations.

Splunk users must have role and/or capability-based authorization to use REST endpoints. Users with an administrative role, such as admin, can access authorization information in Splunk Web. To view the roles assigned to a user, select Settings > Access controls and click Users. To determine the capabilities assigned to a role, select Settings > Access controls and click Roles.

App and user context

Typically, knowledge objects, such as saved searches or event types, have an app/user context that is the namespace. For more information about specifying a namespace, see Namespace in the REST API User Manual.

Splunk Cloud Platform limitations

As a Splunk Cloud Platform user, you are restricted to interacting with the search tier only with the REST API.

Some but not all KV store endpoints are available in Splunk Cloud Platform. Instead, authorized users can access and configure the KV store lookup definitions in the Splunk Cloud Platform user interface. KV store collections, however, cannot be modified with the user interface.

See Access requirements and limitations for the Splunk Cloud Platform REST API in the the REST API Tutorials manual for more information.

App KV Store REST API features

The app KV Store provides the following functions.

  • Create, read, list and delete EAI operations on a collection.
  • Create, read, list and delete indexes for a given collection. All collection methods are EAI-compatible. These are not regular EAI operations because the indexes are stored as attributes on the EAI entity. Users must have collection permission to use these operations for a particular collection.
  • The ability to insert, read, update and delete a single key and key value, for a given collection, provided that you have permission to modify the collection.
    • Duplicate keys are not allowed.
    • All updates are wholesale updates.
    • Partial value updates are not available.
  • The ability to query key-value pairs, for a given collection. For example, to find all the documents that have a host field with a value, use the query 
    {"host": "bar.com"}
    .

Only the following operations are permitted.

  • $gt
  • $gte
  • $lt
  • $lte
  • $ne
  • $and
  • $or,
  • $not.

The API also supports mechanisms for projection, sorting and pagination.

  • Batch reads, inserts, and/or updates for a given collection. This supports high-volume operations and limits network traffic. These operations have the same semantics as their individual counterparts.

Limits

  • 16MB per record
  • 1KB per accelerated field

Collections

A Collection is a container of "documents" or "values". Most documents have a similar structure, although structure is not enforced. For example, a Collection might have Notable Events or entities.

Collections are declared in a collections.conf configuration file, where a stanza is a single collection.

Collection permissioning

Collections are Splunk entities, which means they are permissioned using the Splunk RBAC/ACL system. Only app-level permissions are available for collections. This means that collections can be defined only in the etc/apps/<app>/<default|local> directory, not in etc/users/.... Attempts to create a user-specific Collection using the API fail and Collections created manually in the .conf files are ignored.

Data

A collection stores key-value pairs consisting of a user-specified or autogenerated key and a JSON document-formatted value. A JSON document/object of values is enforced for simplicity instead of using integer or string raw values. For example, {"_key": "10.0.0.1", host: "bar.com"} defines the key ("10.0.0.1") and the full JSON document value.

A key is fetched, updated, and deleted. Partial updates, including array append, are not available. You must set the whole document. Keys are unique within a collection and support only the basic JSON data types: boolean, string, number, object, array, and null.

A value is specified in the _key attribute of the document and, if one is not specified, a random value with a desirable sort order is automatically generated.

A collection is defined in the following directory location. 

/servicesNS/nobody/search/storage/collections/mycollection

You can use the following URLs to access the collection.

  • /servicesNS/nobody/search/storage/collections/mycollection
  • /servicesNS/itay/search/storage/collections/mycollection
  • /servicesNS/mark/search/storage/collections/mycollection

Namespaces are separate and data are not interleaved. Wildcard operations on the <user> or <app> parts of the namespace are not available.

User-specific collections are not supported. All users, including nobody, share a single namespace and _key is unique across all namespaces.

Types

You can define a set of types for some fields in a collection. If a field has no type defined, it uses the type submitted over the API. If a type conversion fails, the insert/update operation is aborted.

Here is an example collection in collections.conf. 

[mycollection]
field.enabled = bool
field.data.range = cidr

The data inserted or updated in this collection have the fields enabled and range-converted to the applicable type. 


* array
* number
* boolean
* time
* string
* cidr


Items need to be specified using the field prefix only if type needs to be enforced for the field. The array type is not enforceable so does not need to be specified.

Arrays

Arrays do not change a nested key name. For example, the key "a.b.c" can refer to {"a": {"b": {"c": 1}}} or {"a": {"b": [{"c": 1}]}}.

Numbers

All strings/numbers/booleans are converted to doubles. If a number fails to convert, it inserts the string instead.

Booleans

All numbers/strings/booleans are converted to booleans. If a boolean fails to convert, it inserts the string instead. Epoch time can be a string or a number. If it fails to convert, the string version is inserted.

Strings

Everything is converted to a string.

CIDR

All provided strings are converted to canonical CIDR strings. Here is an example. 

127.0.0.1       -> 127.000.000.001/32
127.0.0.0/24    -> 127.000.000.000/24
127.0.0/24      -> 127.000.000.000/24

Here is an example of similar canonicalization for IPv6. 

2001:db8::/96               -> 2001:0db8:0000:0000:0000:0000:0000:0000/096
2001:db8:0:0:0:0:0:ffff     -> 2001:0db8:0000:0000:0000:0000:0000:ffff/128

Queries

Combining the Data and Index patterns gives the ability to do basic querying. Queries are limited to the basic operators available in most databases, and at the moment do not expose in-array and not-in-array containers. A query can have the following operators.

  • gt
  • gte
  • lt
  • lte
  • eq
  • neq
  • or
  • and
  • not

Queries are permitted regardless of whether an index covers the query. If it the index does not cover the query, the query takes longer to complete. For example, here is a query to find all Notable Events authored by userA or userB. 

{ "$or": [ { "author": "userA" }, { "author": "userB" } ] }

Use $and to search for a range of values. For example, use the following query to find all events with a time field value between 12 and 13. 

{ "$and": [ { "time": { "$gt": "12" } }, { "time": { "$lt": "13" } } ] }

REST methods

The REST API for App KV Store implements the GET, POST, and DELETE methods described in this reference.

GET

Access a specific {collection}.

Request parameters
None


Returned values

Name Description
disabled Boolean indicating collection state. By default, the value is 0, meaning that the collection is enabled.
field.<fieldName> Field type. One of the following values.
  • array
  • number
  • bool
  • string
  • cidr
  • time
accelerated_fields.<field_name> Field acceleration name and JSON definition.
enforceTypes Boolean indicating if data types are enforced when inserting data into the collection. Defaults to false.
profilingEnabled Profiling status of slow-running operations, affecting profilingThresholdMs. By default, the value is false, meaning that profiling is disabled. If true, profiling is enabled.
profilingThresholdMs Threshold for logging slow-running operations, in milliseconds. Applies only if profilingEnabled is true.
replicate Boolean indicating whether the collection is replicated on indexers. Defaults to false, meaning that this collection is not replicated, and lookups that depend on the collection will not be available. However, if you run a lookup command with local=true, local lookups will still be available.

When true, this collection is replicated on indexers.
replication_dump_maximum_file_size Indicates the maximum file size (in KB) for each dump file when replication_dump_strategy=auto. Defaults to 10240KB.

If this value is larger than concerningReplicatedFileSize, which is set in the distsearch.conf file, the value of concerningReplicatedFileSize is used instead.

KV Store does not pre-calculate the size of the records that will be written to disk, so the size of the resulting files can be affected by the max_rows_in_memory_per_dump setting in the limits.conf file.
replication_dump_strategy One of the following two values.
  • auto: Default. Dumps are stored in multiple files when the size of the collection exceeds the value of replication_dump_maximum_file_size.
  • one_file: Dump files are stored in a single file.
