 * `DOTNET_EventPipeProcNumbers`: Set this to `1` to enable capturing processor numbers in EventPipe event headers. The default value is `0`.
 
+* `DOTNET_EventPipeThreadSamplingRate`: Available in .NET 11+. Sets the interval, in milliseconds, for the EventPipe thread time sampling profiler. When set to `0` or omitted, the runtime uses its built-in default of 10 ms (~100 Hz). This setting is process-global and affects all EventPipe sessions, including on-demand traces started by tools such as [dotnet-trace](./dotnet-trace.md). Setting a large value reduces sampling overhead but also reduces the resolution of any trace collected during the process lifetime.

 * `DOTNET_EventPipeConfig`: Sets up the EventPipe session configuration when starting an EventPipe session with `DOTNET_EnableEventPipe`.
