Splunk® Enterprise

REST API Reference Manual

Splunk Enterprise version 7.2 is no longer supported as of April 30, 2021. See the Splunk Software Support Policy for details. For information about upgrading to a supported version, see How to upgrade Splunk Enterprise.
This documentation does not apply to the most recent version of Splunk® Enterprise. For documentation on the most recent version, go to the latest release.

Metrics Catalog endpoint descriptions

Use the Metrics Catalog REST API to enumerate metrics and the dimensions and dimension values associated with metrics.

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, and must have the list_metrics_catalog capability to use the Metrics Catalog endpoint. 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 > Users. To determine the capabilities assigned to a role, select Settings > Access controls > 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.

Default indexes for Metrics Catalog endpoints

If no metric indexes are defined with the filter parameter, Metrics Catalog endpoints use the default indexes specified for the role of the user. To review or update the default indexes for specific roles, select Settings > Access controls > Roles, select a role, and review or update the Indexes searched by default field.

If the set of default indexes for a role includes a mix of metrics indexes and event indexes, the Metrics Catalog endpoints only use the metrics indexes.

If there are no metrics indexes, the Metrics Catalog endpoints display an empty list.

Splunk Cloud URL for REST API access

Splunk Cloud has a different host and management port syntax than Splunk Enterprise. Use the following URL for Splunk Cloud deployments. If necessary, submit a support case using the Splunk Support Portal to open port 8089 on your deployment. 

https://<deployment-name>.splunkcloud.com:8089

Free trial Splunk Cloud accounts cannot access the REST API.

See Using the REST API in Splunk Cloud in the the Splunk REST API Tutorials for more information.

earliest String Optional. A time string that specifies the earliest time for this search. Can be a relative or absolute time. The default value is -1d.
filter String Optional. A URL-encoded set of one or more key-value pairs, where keys correspond to metric fields such as index or dimension. For example, to specify a dimension named app, use filter=app. To specify two index names and values such as index=index1 and index=index2, use index%3dindex1%26index%3dindex2.
latest String Optional. A time string that specifies the latest time for this search. Can be a relative or absolute time. The default value is now.
list_indexes Boolean Optional. When set to true, the endpoint returns the index or indexes associated with each metric. The default value is false.
