RabbitMQ Queue Checker

A Node.js app to check if any queue on a RabbitMQ is above a pre determined number.

This application is currently quite basic in that it will only check once per set time interval (usually 1 minute) and if the queue is above 0 it will fire off an email and put the timer into another loop (currently 1 hour) where it will not check further. This stops the dreaded morning of 4,000,000 email alerts but doesn't help if anything else gets stuck in that hour.

Running Locally

Make sure you have Node.js and the Foreman installed.

$ git clone location-of-git
$ cd folder-just-created
$ npm install

then each time

$ foreman start
# then
ctrl-c # to exit

The web app should now be running on localhost:5000.

The web interface really is boring and shows nothing exciting (at the moment).

Deploying to Dokku-Alt

This app was built to run on our Dokku-Alt so it should be just a quick

$ git push whateveryoucalledtherepository master

Using an .env file

You can change the behavior of this app either in the index.js file or by using an .env file.


We are using Nodemailer to send email. It can be quickly changed to use SMTP but have a look at Mailgun which is ideal for this kind of error reporting.

var transport = nodemailer.createTransport(smtpTransport({
  host: 'localhost',
  port: 25,
  auth: {
    user: 'username',
    pass: 'password'
