 Since version 6.17, **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//​.

One specific use of actions is covered in the tutorial, [[realtime:​documentation:​howto:​tools:​rtla:​processor_trace|Using rtla with perf processor trace]].
