When you are connected to the profiled application, use the "Threads" tab to track the live threads.
The telemetry information is remembered in a circular buffer in the profiler agent memory. This allows you to connect to a profiled application on demand and discover how the application behaved in the past.
The buffer capacity is 1 hour by default, and can be changed with the startup option telemetrylimit.
Start/stop stack telemetry
The thread stack and state telemetry information can be very useful because it allows you to connect to the profiled application on demand and discover how the application behaved in the past. In most cases, there is no significant overhead of collecting this information, and thus you do not need to stop it.
However, you can stop stack telemetry to ensure minimum profiling overhead.
When you are connected to the profiled application, use toolbar button to start/stop the telemetry.
