Add this line to your application's Gemfile:

gem 'sidekiq-prometheus-exporter', '~> 0.1'

And then execute:

$ bundle

Or install it yourself as:

$ gem install sidekiq-prometheus-exporter -v '~> 0.1'

Rack application

For a fresh new application to expose metrics create file with next code inside

require 'sidekiq'
require 'sidekiq/prometheus/exporter'

Sidekiq.configure_client do |config|
  config.redis = {url: 'redis://<your-redis-host>:6379/0'}

run Sidekiq::Prometheus::Exporter.to_app

Use your favorite server to start it up, like this

$ bundle exec rackup -p9292 -o0.0.0.0

and then curl

Rails application

When you have rails application, it's possible to mount exporter as a rack application in your routes.rb

Rails.application.routes.draw do
  # ... omitted ...

  # For more information please check here
  require 'sidekiq/prometheus/exporter'
  mount Sidekiq::Prometheus::Exporter => '/metrics'

Use rails server from bin folder to start it up, like this

$ ./bin/rails s -p 9292 -b

and then curl

Sidekiq Web (extream)

If you are ok with metrics being exposed via Sidekiq web dashboard because you have it inside your private network or only Prometheus scraper will have access to a machine/port/etc, then add a few lines into your web

require 'sidekiq/web'
require 'sidekiq/prometheus/exporter'


and then curl https://<your-sidekiq-web-uri>/metrics


If we are talking about isolation you can run already prepared official rack application in the Docker container by using the public image (check out this README for more)

$ docker run -it --rm \
             -p 9292:9292 \
             -e REDIS_URL=redis://<your-redis-host>:6379/0 \

and then curl


And finally the cloud solution (who don't these days). Easy to install, easy to use. A fully-functioning Helm-package based on official Docker image, comes with lots of configuration options

$ helm repo add strech
"strech" has been added to your repositories

$ helm install strech/sidekiq-prometheus-exporter --name sidekiq-metrics

to curl your metrics, please follow the post-installation guide


If you want to see at the exporter startup time a banner about which exporters are enabled add this call to your (but after exporter configure statement)

require 'sidekiq/prometheus/exporter'

puts Sidekiq::Prometheus::Exporter.banner

:anger: if you don't see your banner try to output into STDERR instead of STDOUT

Sidekiq Contribs

By default we try to detect as many as possible sidekiq contribs and add their metrics to the output. But you can change this behaviour by configuring exporters setting

require 'sidekiq/prometheus/exporter'

# Keep the default auto-detect behaviour
Sidekiq::Prometheus::Exporter.configure do |config|
  config.exporters = :auto_detect

# Keep only standard (by default) and cron metrics
Sidekiq::Prometheus::Exporter.configure do |config|
  config.exporters = %i(cron)

:bulb: if you did't find the contrib you would like to see, don't hesitate to open an issue and describe what do you think we should export.
