Stack Trace on .net Agent Span

Elastic Observability APM
2

Hi @xitaocrazy,

in the 1.0.0-beta1 we only capture stack traces for outgoing HttpClient requests, but we recently merged a couple of PRs addressing exactly your questions. Those will be included in the next release.

In sum, we'll do in .NET what other agents do:

  • Every span that takes at least 5ms will contain a stacktrace
  • we add the ELASTIC_APM_STACK_TRACE_LIMIT config to limit the depth of the stack trace
  • we add the ELASTIC_APM_SPAN_FRAMES_MIN_DURATION config to change the 5ms default to capture stack traces for shorter (or only for longer) spans.

All this is already on master.
