Connect to profiled application

Once you have profiled application running, you should connect to it to obtain and analyze profiling results.

All detected JVMs are shown in the "Monitor Applications" list on Welcome screen. Connect to the application you want to profile by clicking on its name.

The colored circle indicates the profiler agent status in the Java process. Green circle means the agent has been loaded, and connection will happen immediately. Orange circle means the agent has not been loaded yet, and the profiler will automatically attach the agent before connection.
