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.

@kaylareopelle What progress has been made and what else remains to be done? We would like to use this for logging from our ruby code.

Hi @cidemaxio! Thanks for reaching out. It's great to hear you'd like to use OTel Ruby logs.

Here's the project board for the Logs signal that tracks what remains to be done. I have a draft PR for the OTLP exporter on my fork with a todo list in the description for work to do before opening the PR in the main repo.

There is at least one other PR that needs to be opened for the SDK/API regarding configuration and instrument registries. After both that PR and #1696 are merged, we should be ready to release the logs SDK, API and OTLP exporter gems.
