Contrib Repository

The opentelemetry-ruby-contrib repository contains instrumentation libraries for many popular Ruby gems, including Rails, Rack, Sinatra, and others, so you can start using OpenTelemetry with minimal changes to your application. See the contrib README for more details.

Versioning

OpenTelemetry Ruby follows the versioning and stability document in the OpenTelemetry specification. Notably, we adhere to the outlined version numbering exception, which states that experimental signals may have a 0.x version number.

Compatibility

OpenTelemetry Ruby ensures compatibility with the current supported versions of the Ruby language.
