Connect to profiled application
Once the profiled application is running, you should connect to it to obtain and analyze profiling results.
All detected .NET applications 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 CLR 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.
Local applications are shown under the node with icon. Applications running on the remote machines are shown under their own nodes with icon. To add a new remote machine click . See Profile remote applications to learn more.
Profiler hides development tools, such as IDEs, in the list by default. This can be configured by clicking on the icon.
If you do not see your application it the list, please read profiling troubleshooting.
After a connection is established successfully, the profiling session tab opens. It displays the profiled application telemetry, and provides the toolbar to control profiling.
|Capture performance snapshot - save the profiling results to a file, for comprehensive analysis|
|CPU profiling controls|
|Thread stack telemetry control|
|Capture memory snapshot|
|Object allocation recording controls|
|Force garbage collection in the profiled application|
|Exception profiling controls|
|Triggers - configure actions automatically performed on events|
|Clear all telemetry charts|
|Pause - stop/start receiving data from profiled application|
|Refresh - immediately receive profiling data from the profiled application and update the views|
|Transfer snapshots during remote profiling|
You can close the profiling session tab by using File | Close Profiling Session.
You can connect to and disconnect from the profiled application as many times as you wish during its run time.
