When you choose Monitor Application in the Select Profiling Task dialog box, the target application is run without any instrumentation. The results show only high-level information about some properties of the target JVM, including thread activity and memory allocations.
To monitor an application:
When you click Run, the target application launches and the profiling task starts. Click the Telemetry button or the Threads button in the Profiler window to view the results.
Monitoring thread activity
By default, application thread activity is not monitored. You can start monitoring thread activity at any time during a profiling session by opening the Threads tab and clicking the Threads button.
