Functionality aside from UseProfiler()?

[christophwille]

Is there anything? Eg so I can say in code "Start profiler when memory > 40%" or "Start immediately and trace until minute 3"

Hey @christophwille , will this satisfy what you are looking for:

You shall be able to do Profile Now and combine it with the memory trigger.

I know those, but: I want to ship the container, activated with C# (Use case: container startup is immediately stressing CPU and memory). Also I'd like to say stop the profile & upload (Use case: I know that ten seconds later the container crashes and the upload won't succeed any more if I do it later)

Ah, let me confirm I understand you, this time :-). What you want is capabilities to run profiler by code. Some scenarios like:

1. Run Profiler for a given period.
2. Trigger Profiler on conditions.

So, you are looking for APIs like this (pseudo code):

// _profilerService is injected
_profilerService.StartProfiler(duration: TimeSpan.FromSeconds(30)); // Run profiler, by code, for 30 seconds.

// Or something like:

if (memoryUsage > .7)
{
    profilerService.StartProfiler(duration: TimeSpan.FromSeconds(15));
}

Does that sound right?

Yes, exactly those are the scenarios I outlined.

Additionally, it would be nice to have a "manual" StopProfiler() capability - eg when I know that some operation I wanted to profile is done (background service, ...)

@christophwille I see. Won't that been an issue if end up having huge trace files because the condition never met to stop the profiler? :-)

Well, an option to say "and btw, collect a maximum of X MiB and then stop" would also be nice to have.
