OpenTelemetry activity exception tag mapping

dotTrench opened this issue · comments

Are you requesting automatic instrumentation for a framework or library? Please describe.

  • Framework or library name : OpenTelemetry.Api
  • Library type: Tracing (Activities)
  • Library version: 1.5.0

Is your feature request related to a problem? Please describe.
Whenever using the DD_TRACE_OTEL_ENABLED and calling the extension method Activity.RecordException(Exception ex) defined in the OpenTelemetry.Api package. we expect the exception to be recorded in a way similiar to ISpan.SetException(Exception ex).

Currently the span displayed in the UI does not contain any stack trace or error type.

Describe the solution you'd like
Translate the semantic conventions for exception tags described here into datadog specific "error" tags. i.e.

exception.stack -> error.stack
exception.message -> error.message
exception.type -> error.type

Describe alternatives you've considered
As a workaround we could manually set tags to the datadog specific tags when manually creating activities or using "Enrichers" when using instrumentation libraries where it's supported.

Hi @dotTrench, thanks for flagging that, this is actually something @bouwkast is working on at the moment, so we should have a fix for it soon. Thanks!
