OpenTelemetry RubyKafka Instrumentation

The RubyKafka instrumentation is a community-maintained instrumentation for RubyKafka, a client library for Apache Kafka.

How do I get started?

Install the gem using:

gem install opentelemetry-instrumentation-ruby_kafka

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


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

OpenTelemetry::SDK.configure do |c|
  c.use 'OpenTelemetry::Instrumentation::RubyKafka'

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

OpenTelemetry::SDK.configure do |c|


Example usage can be seen in the ./example/ruby_kafka.rb file here

How can I get involved?

The opentelemetry-instrumentation-ruby_kafka gem source is on github, along with related gems including opentelemetry-api and opentelemetry-sdk.

The OpenTelemetry Ruby gems are maintained by the OpenTelemetry-Ruby special interest group (SIG). You can get involved by joining us in GitHub Discussions or attending our weekly meeting. See the meeting calendar for dates and times. For more information on this and other language SIGs, see the OpenTelemetry community page.
