Sidekiq CloudWatch Metrics

Runs a thread inside your Sidekiq processes to report metrics to CloudWatch useful for autoscaling and keeping an eye on your queues.

Optimised for Sidekiq Enterprise with leader election, but works everywhere!

Installation

Add this gem to your application’s Gemfile near sidekiq and then run bundle install:

gem "sidekiq"
gem "sidekiq-cloudwatchmetrics"

Usage

Add near your Sidekiq configuration, like in config/initializers/sidekiq.rb in Rails:

require "sidekiq"
require "sidekiq/cloudwatchmetrics"

Sidekiq::CloudWatchMetrics.enable!

By default this assumes you're running on an EC2 instance with an instance role that can publish CloudWatch metrics, or that you've supplied AWS credentials through environment variables that aws-sdk expects. You can also explicitly supply an aws-sdk CloudWatch Client instance:

Sidekiq::CloudWatchMetrics.enable!(client: AWS::CloudWatch::Client.new)

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.
