Export LogRecord.Exception data when using otlp exporter

[vishweshbankwar]

Opening this issue to track progress on exporting attributes corresponding to LogRecord.Exception in OTLP exporter. The semantic conventions for these attributes are not yet stable and hence the attributes are not part of stable OTLP log exporter. The attributes will be available in only the pre-release versions of the exporter.

Does this mean when using LogError the exception that is passed as parameter its stacktrace is currently not send?

Correct : https://github.com/open-telemetry/opentelemetry-dotnet/blob/main/src/OpenTelemetry.Exporter.OpenTelemetryProtocol/CHANGELOG.md#160-rc1

Thanks for the details; just curious; does it mean there is a non stable version around that is up to date but just still contains this information ?

[cijothomas]

The changelog shows the version Exception was removed. So if you use the version prior to it, you'll get exceptions.

The attributes will be available in only the pre-release versions of the exporter.

The above is misleading statement.. Not sure what it is supposed to mean? @vishweshbankwar could you clarify?

Following up on this: The ability to export these attributes are available on https://www.nuget.org/packages/OpenTelemetry/1.7.0-alpha.1

open-telemetry/semantic-conventions#619 Once this is done, we can make the exception part as default without experimental feature.

https://github.com/open-telemetry/semantic-conventions/blob/main/docs/exceptions/exceptions-logs.md#semantic-conventions-for-exceptions-in-logs is stable now., and OTLP Logexporter can bring back this functionality now.
