| - | **rtla** supports integrating external tools into latency measurement by the means of //actions//. Actions can run a command or send a signal to a process whenever tracing is stopped on latency threshold set with //-T/-i/-a// (for timerlat; //-s/-S/-a// for osnoise), or at the end of tracing. A special action resumes tracing after stop, if requested. | + | Since version 6.17, **rtla** supports integrating external tools into latency measurement by the means of //actions//.
