Monitoring in the Application Server

Use monitoring to observe the runtime state of various components and services deployed in a server instance of theApplication Server. With the information on the state of runtime components and processes, it is possible to identify performance bottlenecks for tuning purposes, aid capacity planning, predict failures, do root cause analysis in case of failures, and ensure that everything is functioning as expected.

Turning monitoring on reduces performance by increasing overhead.
