When analyzing the performance of software applications, not only timing, but also resource utilization is of importance. The Software Telemetry extension supports the recording of basic performance profile related resource utilizations commonly used in many software profiler tools. The resource utilizations covered in this extension are: CPU usage, thread usage and memory usage.

Relation to other extensions

The Software Telemetry extension builds on the Software Event extension to store standard details for software events.
