Overview

Integration provides the basic contract of a tracing integration.

An example for a simple instrumentation of a fictional ‘BillingApi::Client`:

“‘ require ’datadog’

module BillingApi

class Integration
  include ::Datadog::Tracing::Contrib::Integration

  register_as :billing_api # Register in the global tracing registry

  def self.available?
    defined?(::BillingApi::Client) # Check if the target for instrumentation is present.
  end

  def new_configuration
    Settings.new
  end

  def patcher
    Patcher
  end
end

class Settings < ::Datadog::Tracing::Contrib::Configuration::Settings
  # Custom service name, if a separate service is desirable for BillingApi calls.
  option :service, default: nil
end

module Patcher
  include ::Datadog::Tracing::Contrib::Patcher

  def self.patch
    ::BillingApi::Client.prepend(Instrumentation)
  end
end

module Instrumentation
  def api_request!(env)
    Tracing.trace('billing.request',
                         type: 'http',
                         service: Datadog.configuration.tracing[:billing_api][:service]) do |span|
      span.resource = env[:route].to_s
      span.set_tag('client_id', env[:client][:id])

      super
    end
  end
end

end

Datadog.configure do |c|

c.tracing.instrument :billing_api # Settings (e.g. `service:`) can be provided as keyword arguments.

end “‘
