OpenTelemetry Rage Instrumentation

The OpenTelemetry Rage instrumentation provides automatic observability for Rage, a fiber-based framework with Rails-compatible syntax.

This instrumentation enables comprehensive tracing and logging for Rage applications:

• Creates spans for HTTP requests, WebSocket messages, event subscribers, and deferred tasks
• Propagates OpenTelemetry context across fibers created via Fiber.schedule and deferred tasks
• Enriches logs with trace and span IDs for correlated observability

How do I get started?

Install the gem using:

gem install opentelemetry-instrumentation-rage

Or, if you use bundler, include opentelemetry-instrumentation-rage in your Gemfile.

Usage

To use the instrumentation, call use with the name of the instrumentation:

OpenTelemetry::SDK.configure do |c|
  c.use 'OpenTelemetry::Instrumentation::Rage'
end

Alternatively, you can also call use_all to install all the available instrumentation.

OpenTelemetry::SDK.configure do |c|
  c.use_all
end

Examples

Example usage can be seen in the ./example/trace_demonstration.ru file
