Queue

​

Overview

Cachet uses a queue to send Configuring Mail and Beacons without slowing down the rest of the application. This can be setup in a variety of ways.

​

Supervisor

The recommended setup for the queue is to use Supervisor.

Supervisor is a process manager which makes managing a number of long-running programs a trivial task by providing a consistent interface through which they can be monitored and controlled.

​

Cachet v2.4

[program:cachet-queue]
command=php artisan queue:work --delay=1 --sleep=1 --timeout=1800 --tries=3
directory=/var/www/cachet/
redirect_stderr=true
autostart=true
autorestart=true
user=cachet

​

Cachet v2.3

You should create a Supervisor configuration file named /etc/supervisor.d/conf/cachet.conf

[program:cachet-queue]
command=php artisan queue:work --daemon --delay=2 --sleep=1 --tries=3
directory=/var/www/cachet/
redirect_stderr=true
autostart=true
autorestart=true
user=cachet

​

Queues Using The Scheduler

The default installation of Cachet sets the queue type to database which means that all jobs are stored within your database and is then processed by a cron job which calls an artisan command from within the project directory.

You’ll need to create a new cron job, in Ubuntu it’s a case of running crontab -e and adding this line:

* * * * * php /path/to/artisan schedule:run >> /dev/null 2>&1

Close the file and the cron job will now begin running, processing any confirmation and incident emails.

​

Synchronous Queue

If you cannot add a queue job, another alternative is to process all of the jobs immediately after they are created.

To set this up change the .env file with the following setting:

QUEUE_DRIVER=sync
