Horizon Configuration

Horizon provides a beautiful dashboard and code-driven configuration for your System. Horizon allows you to easily monitor your queue system such as job throughput, runtime, and job failures. All of your worker configuration is stored in a single, simple configuration file.

Horizon Dashboard

Deploying Horizon

If you are deploying Horizon to a live server, you should configure a process monitor to monitor the php artisan horizon command and restart it if it quits unexpectedly. When deploying fresh code to your server, you will need to instruct the master Horizon process to terminate so it can be restarted by your process monitor and receive your code changes.

If you are not install supervisor yet then run sudo apt install -y supervisor to install supervisor. Run the following command to check supervisor is installed.

supervisord --version

Configuring Horizon

Supervisor configuration files are typically stored in the /etc/supervisor/conf.d directory. Within this directory, you may create any number of configuration files that instruct supervisor how your processes should be monitored. For example, let's create a horizon.conf file that starts and monitors a horizon process:

[program:horizon]
process_name=%(program_name)s
command=php /var/www/html/project_directory/artisan horizon
autostart=true
autorestart=true
user=root
redirect_stderr=true
stdout_logfile=/var/log/horizon.log
stopwaitsecs=3600

Replace project_directory to your project directory name. If your server does not have root user, then change the user as well. Make sure /var/log/horizon.log the file is created and has write permission

Update Queue Connection

Update your queue connection to redis in your .env file:

QUEUE_CONNECTION=redis

After updating .env file. Clear your config file by following command:

php artisan clear:all

Starting Supervisor

Once the configuration file has been created, you may update the Supervisor configuration and start the processes using the following commands:

supervisorctl reread

supervisorctl update

supervisorctl start horizon

You need to run the following command to check if your supervisor is running successfully.

supervisorctl status
