Use the Opentelemetry Ruby SDK to send telemetry data to Moonbase.

What you need to start

  • A working Ruby environment with Ruby 2.5 or higher

  • A service written in Ruby

  • Moonbase Project Id

  • Moonbase api token

Needed dependencies

Add the following dependencies to your Gemfile

gem 'opentelemetry-sdk'
gem 'opentelemetry-exporter-otlp'
gem 'opentelemetry-instrumentation-all'

Install after adding

bundle install

Set the exporter endpoint enviroment variable

export OTEL_EXPORTER_OTLP_ENDPOINT="http://api.moonbase.hqdev:8085/v1/traces"

Configure Opentelemetry SDK

# config/initializers/opentelemetry.rb
require 'opentelemetry/sdk'
require 'opentelemetry/instrumentation/all'
require 'opentelemetry-exporter-otlp'
 
otel_exporter = OpenTelemetry::Exporter::OTLP::Exporter.new(endpoint: ENV['OTEL_EXPORTER_OTLP_ENDPOINT'])
processor = OpenTelemetry::SDK::Trace::Export::BatchSpanProcessor.new(otel_exporter)
 
OpenTelemetry::SDK.configure do |c|
  c.service_name = 'dice-ruby'
  c.add_span_processor(processor)
  c.use_all() # enables all instrumentation!
end
