The Splunk ITSI Module for Application Performance Monitoring will be EOLed soon The Splunk ITSI Module for Application Performance Monitoring (APM) enables a Splunk IT Service Intelligence user or administrator to get up and running quickly with pre-packaged key performance indicators (KPIs), measuring either metrics or logs from APM tools to get an overview of the health of their applications. ITSI combines this information with other data and other modules to help users understand overall service performance. This module provides out-of-the-box content for data ingested through the Splunk Add-on New Relic and the Splunk Add-on for AppDynamics.
