Correlation search overview for ITSI

A correlation search is a recurring search that scans multiple data sources for defined patterns. You can configure a correlation search to generate a notable event (alert) when search results meet specific conditions. Use Episode Review to review notable events that your correlation searches generate and to initiate the investigative process of determining root cause.

You can use an ITSI correlation search to ingest third-party alerts as ITSI notable events. If you are creating a correlation search to ingest alerts from a third-party product, such as Nagios or SCOM, see Ingest third-party alerts as ITSI notable events for specific instructions.

Do not create correlation searches by manually editing $SPLUNK_HOME/etc/apps/itsi/local/savedsearches.conf. The search will not appear on the correlation search lister page. Always create correlation searches directly in the IT Service Intelligence app.

Predefined correlation searches

The following correlation searches are delivered with ITSI. They are all disabled by default except Splunk App for Infrastructure Alerts. You can enable them and modify them to meet your needs.
