AppDynamics includes many tools and views designed to help you diagnose application-related problems. 

Access Troubleshooting

When starting to troubleshoot an application problem, you should begun in the Troubleshoot section of the UI. You can access from the left-hand navigation pane of the Controller UI in an application context.

The area includes pages for analyzing slow response times, errors and exceptions, and health rule violations. It also provides access to war rooms, an area of the UI dedicated to troubleshooting a specific problem.
