The Resume/Suspend toggle button is used to start or stop the trace. This toggle button appears on launching the debug session of an application. The default status of trace collection is ON. Therefore, when the application is debugged, the Suspend toggle button appears next to the data source. When clicked, the button toggles to Resume.
To stop trace collection:
The Suspend toggle button appears next to the data source name in the Software Analysis view.
The button toggles to Resume.
The trace is not collected.
To start trace collection:
The button toggles to Suspend.
The trace is collected.
The toggle button disappears when you click Resume in the Debug view or terminate the debug session. After clicking Suspend in the Debug view, it is visible again with the last selected status.
