Sidekiq::Tracer

OpenTracing instrumentation for Sidekiq (both client, and server-side).

Installation

Add this line to your application's Gemfile:

gem 'sfx-sidekiq-opentracing'

And then execute:

$ bundle

Or install it yourself as:

$ gem install sfx-sidekiq-opentracing

Usage

The gem hooks up into Sidekiq through middlewares - similar to Rack. Both server-side, and client-side middlewares are supported.

  • Client-side middleware runs before the pushing of the job to Redis and injects the current span context into the job's metadata.
  • Server-side runs around job processing, extracts the context from the job metadata and creates a new span for the server-side proessing.

To instrument Sidekiq (both sides), you need to specify at least a tracer instance and optionally an active span provider - a proc which returns a current active span. The gem plays nicely with spanmanager.

require "sidekiq-opentracing"

Sidekiq::Tracer.instrument(tracer: OpenTracing.global_tracer,
                           active_span: -> { OpenTracing.global_tracer.active_span })

And you are all set.

The code below shows how to register and manage middlewares on your own.

Server-side:

Sidekiq.configure_server do |config|
  config.client_middleware do |chain|
    chain.add Sidekiq::Tracer::ClientMiddleware, tracer: OpenTracing.global_tracer
  end

  config.server_middleware do |chain|
    chain.add Sidekiq::Tracer::ServerMiddleware, tracer: OpenTracing.global_tracer
  end
end

Client-side:

Sidekiq.configure_client do |config|
  config.client_middleware do |chain|
    chain.add Sidekiq::Tracer::ClientMiddleware, tracer: OpenTracing.global_tracer
  end
end

Development

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 tags, and push the .gem file to rubygems.org.
