OTLP Exporter for Logs

[kaylareopelle]

Our current OTLP exporter is set up to exclusively send traces. This issue will either adapt current exporters or create a new, temporary exporter to send logs over OTLP. Support for HTTP will likely come first, followed by gRPC.

Hey @kaylareopelle, do you know where this project is at? Just curious when we might get to use a more generalized logging exporter. Thanks.

Hi @travisbell thanks for checking in! Apologies about the delay here.

There is an unreviewed OTLP logs exporter, along with other code to make Ruby spec-compliant for the Logs signal, available in this PR on my fork: kaylareopelle#6

The current process is to release small parts of this code to the main opentelemetry-ruby repository for review, and then revise the WIP branch as needed. I don't have a good sense of when all those code will be merged into main.

If you'd like to test out the WIP logs implementation, you can follow the instructions in this gist: https://gist.github.com/kaylareopelle/76079747c1a7528449670b8bd1c78893

I also have a demo repository that integrates OpenTelemetry logs into a small Rails application: https://github.com/kaylareopelle/otel_ruby_logs_demo

I'm updating the branches about once a week to stay in sync with the latest changes upstream.

If you decide to give this experimental code a try, please let me know how it goes. You can comment here, open an issue on the demo repo, or add a comment to the gist.
