OpenTelemetry::Instrumentation::Grpc

OpenTelemetry instrumentation for users of the grpc gem

Install the gem and add to the application's Gemfile by executing:

$ bundle add opentelemetry-instrumentation-grpc

If bundler is not being used to manage dependencies, install the gem by executing:

$ gem install opentelemetry-instrumentation-grpc

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

OpenTelemetry::SDK.configure do |c|
  c.use 'OpenTelemetry::Instrumentation::Grpc', {
    peer_service: "Example",
    allowed_metadata_headers: [],
  }
end

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

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

You also need to make sure your stubs are using the interceptor, e.g.

otel = OpenTelemetry::Instrumentation::Grpc.client_interceptor
SomeService::Stub.new(host, credentials, *args, **kwargs, interceptors: [otel])

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.
