OpenTelemetry extensions

These libraries are ment as extensions for the Open Telemetry project. They provide functionality that makes working with traces, and logs easier.

Currently, there is support for:

• http severs through otelmiddleware
• logging with zerolog, slog, logrus

More extensions might follow for other logging libraries and more.

Update VERSIONS.md file, increase number accordingly. Create a release tag using the following command

git tag -a otelslog/v0.0.0 -sm 'message'
git push origin otelslog/v0.0.0

For any other submodule replace the otelslog name with the right subproject name.

When the tag is pushed, the proxy can be triggered to update as follows

curl https://proxy.golang.org/github.com/vincentfree/opentelemetry/otelzerolog/@v/v0.0.0.info
