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.

Usage

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

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

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

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

Configuration options

OpenTelemetry::SDK.configure do |c|
  c.use 'OpenTelemetry::Instrumentation::Mongo', {
    # Sets how db_statement appears in your traces. The options are:
    # :obfuscate - (default) query parameters are visible, but values are masked.
    # :include - query parameters and values are both fully visible.
    # :omit - db_statement is omitted entirely.
    db_statement: :include,
  }
end

Example

To run the example:

• Start MongoDB using docker-compose
  • docker-compose up mongo
• In a separate terminal window, cd to the examples directory and install gems
  • cd example
  • bundle install
• Run the sample client script
  • ruby mongo.rb

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