This document provides an overview of how Splunk can be used to gain operational intelligence from machine data. It demonstrates how Splunk allows users to search machine data, correlate infrastructure entities with applications and services, monitor applications and services, and create tickets and alerts. Specifically, it shows how a user can search log data to troubleshoot a phone call about application issues, map entities to applications and services, view related dashboards, and ultimately create a ticket and scheduled alert to notify teams proactively about long database queries.
