Laravel provides excellent support for queued jobs. It's very easy to put something on a queue and out of the box a lot of queue backends such as Beanstalkd, SQS and Redis are supported. Most of the time queued jobs will perform their job without any problem. But have you considered that a queued job can fail too?

Laravel can create a failed jobs table and write a record when a queued jobs fails. There is even a command to retry a failed job:

php artisan queue:retry 5

That's nice! But how do you know if there is a job that failed? Sure you could check the failed jobs table from time to time, but I promise you after a while you won't do that anymore. If you have many applications, checking all those failed job tables will get downright tedious.

Once it is installed you will receive a mail whenever this event occurs. Integration with Slack comes built-in as well. Here's how a Slack notification looks like:
