OpenTelemetry Mongo Instrumentation

The OpenTelemetry Mongo Ruby gem is a community maintained instrumentation for Mongo.

How do I get started?

Install the gem using:

gem install opentelemetry-instrumentation-mongo

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


To install the instrumentation, call use with the name of the instrumentation.

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

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

OpenTelemetry::SDK.configure do |c|


To run the example:

  1. Start MongoDB using docker-compose

    • docker-compose up mongo

  2. In a separate terminal window, cd to the examples directory and install gems

    • cd example

    • bundle install

  3. Run the sample client script

    • ruby mongo.rb

This will run a few MongoDB commands, printing OpenTelemetry traces to the console as it goes.

How can I get involved?

The opentelemetry-instrumentation-mongo 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.
