I actually created that enum for exactly that ;-) To be able to add different metrics in the future. Which is why it states "PID". I actually did think about adding things like TRACECMD_ANALYZE_FL_IRQ To say this is to add irq interruptions. Perhaps even add: TRACECMD_ANALYZE_FL_STOLEN for guest stolen times. I haven't decided on that API yet. Perhaps we could add new custom timings too, and include them somehow. I have to think about a good API to use. -- Steve
