**APM Agent version** :  
Elastic.Apm/1.0.0-beta1

I am using the .net agent and there is no stack trace information in my spans, as in the image

There is a way to capture the call stack information and add it on Spans? any configuration or option in open API (I didn't find anything).

Thanks for attention.

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.

Docs: [https://www.elastic.co/guide/en/apm/agent/dotnet/current/config-stacktrace.html](https://www.elastic.co/guide/en/apm/agent/dotnet/current/config-stacktrace.html)

All this is already on `master`.

Great news, thanks @GregKalapos.  
I will publish it in my local environment to test, and keep waiting for the next release.
