Splunk® IT Service Intelligence

Install and Upgrade Manual

Configure indexes in ITSI

IT Service Intelligence (ITSI) implements custom indexes for event storage. All ITSI indexes are listed in $SPLUNK_HOME/etc/apps/SA-IndexCreation/default/indexes.conf.

  • In a single instance deployment, the installation of ITSI creates the indexes in the default path for data storage.
  • In a Splunk Cloud Platform deployment, customers work with Splunk Support to set up, manage, and maintain their cloud index parameters. See Manage Splunk Cloud indexes in the Splunk Cloud Admin Manual.
  • In a distributed deployment, create the indexes on all Splunk platform indexers or search peers.

For detailed examples of configuring indexes, see indexes.conf.example in the Splunk Enterprise Admin Manual.

ITSI indexes

The following table describes the indexes available in $SPLUNK_HOME/etc/apps/SA-IndexCreation/default/indexes.conf:

Index Description
anomaly_detection An internal index used to support trending and cohesive anomaly detection in ITSI.
itsi_grouped_alerts Stores active episode data.
itsi_im_meta This events index is used for metadata from the default data integrations. For more information see, ITSI entity discovery searches in the Entity Integrations Manual.
itsi_im_metrics This metrics index is used for metrics from the default data integrations. For more information see, ITSI entity discovery searches in the Entity Integrations Manual.
itsi_import_objects This events index is used by ITSI in the entity creation process. For more information, see Overview of entity integrations in ITSI in the Entity Integrations Manual.
itsi_notable_audit Stores all audit events for episodes, including actions, comments, status change, and owner change.
itsi_notable_archive Stores episode metadata (tags and comments) that has been moved from the KV store after a default 6 month retention period, which begins when you close an episode in the UI. Moving data from the KV store removes extraneous data and helps improve performance.
itsi_summary Stores the results of scheduled KPIs searches. Summary indexing lets you run fast searches over large data sets by spreading out the cost of a computationally expensive report over time.
itsi_summary_metrics A metrics index that stores the results of scheduled KPI searches. Every KPI is summarized in both the itsi_summary events index and the metrics index. This index improves the performance of the searches dispatched by ITSI, particularly for very large environments.
itsi_tracked_alerts Stores active raw notable event data.
snmptrapd Stores events coming in from SNMP traps. For more information, see Ingest SNMP traps into ITSI.
