    This page lists these types of events generated in AppDynamics, specifically:

    • Event types that are common to the platform, such as UI, configuration, and licensing-related events
    • Events generated by the alert and response system
    • Application monitoring events

    Information on event types that are specific to a platform module, if available, appears with the module-specific documentation. For example, Database Agent events are listed on Database Agent Events Reference

    Event types listed here that are not visible in the UI can be retrieved using the AppDynamics REST API.

    Description: The agent sent an internal event containing activity traces.
    Activity traces enable the tracing of a code path that passes through a specified class/method. The App Agent for Java uses them to provide object instance tracking (OIT) and automatic leak detection (ALD)
