Sidekiq Queue Status

Rails Middleware to add /queue-status endpoint. Useful for pinging services such as Icinga or Nagios.

Lists latency for each sidekiq queue. The latency is the number of seconds the oldest job (next in line) is waiting to be performed.

Under normal circumstances returns a 200 OK status code. When latency is higher than the 30s default threshold, or when the failure rate on the current day is higher than 10%, a 503 Service Unavailable is returned.

Thresholds are configurable by setting config.queue_tresholds hash. Key is queue name, value is latency threshold in seconds. Set config.queue_failure_rate to override the default failure rate.

# config/application.rb
Application.configure do
  config.queue_tresholds['batch'] = 10.minutes
  config.queue_failure_rate = 5
end

Response body is a JSON object, listing the latencies of all queues and an array of error messages explaining which queues triggered a threshold error.

{
  "latencies": {
    "batch": 200,
    "default": 1,
  },
  "failure_percentage": 25
  "errors": ["Queue batch above threshold of 100", "Failure rate above 5%"]
}

Add this line to your application's Gemfile:

gem 'sidekiq_queue_status'

And then execute:

$ bundle

Or install it yourself as:

$ gem install sidekiq_queue_status
