NiftyAlert

The gem will let you report when something reaches a threshold, such as a job queue, and will intelligently alert whoever or whatever is configured to receive alerts.

Add this line to your application's Gemfile:

gem 'nifty_alert'

Or install it yourself as:

$ gem install nifty_alert

Set up recipients, maybe in a Rails initializer. Recipients can be Slack channels, with email support coming soon.

NiftyAlert.recipients = [
  "https://mycompany.slack.com/services/hooks/slackbot?token=123abc4567def&channel=%23dev"
]

Report whatever you would like to monitor, such as the number of jobs in your queue, along with a threshold:

class EmailJob
  def before(job)
    nifty_alert = NiftyAlert.new(:job_queue)
    nifty_alert.report(Delayed::Job.count, 1_000)
  end

  ...
end

If the threshold has been reached, your Slack channel will be notified.

Don't worry, NiftyAlert will only alert you of an overage once every 15 minutes.
