Configuring Laravel Horizon

You can customize Horizon's behavior by modifying the configuration file located at config/horizon.php. Here’s a sample configuration to get you started:

<?php

return [
    'environments' => [
        'production' => [
            'supervisor-1' => [
                'connection' => 'redis',
                'queue' => ['default'],
                'balance' => 'auto',
                'processes' => 10,
                'tries' => 3,
            ],
        ],

        'local' => [
            'supervisor-1' => [
                'connection' => 'redis',
                'queue' => ['default'],
                'balance' => 'simple',
                'processes' => 3,
                'tries' => 3,
            ],
        ],
    ],
];

In this example, we define different settings for the production and local environments, specifying the number of processes and how jobs should be balanced.

Monitoring and Managing Jobs

Horizon provides an intuitive interface for monitoring and managing jobs. Here’s how you can use it effectively:

  • Real-Time Monitoring: The dashboard shows real-time statistics about job processing, including the number of jobs processed, failed jobs, and the time taken for each job.
  • Retrying Failed Jobs: You can easily retry failed jobs from the dashboard, which helps in quickly addressing issues without diving into the code.
  • Managing Workers: Horizon allows you to see the status of each worker, including which job they are processing and their runtime statistics.

Setting Up Alerts and Notifications

Horizon can notify you about various events through your preferred channels. You can configure this in the config/horizon.php file. For example, you can set up Slack notifications for failed jobs:

'notifications' => [
    'slack' => [
        'webhook_url' => env('SLACK_WEBHOOK_URL'),
        'channel' => '#your-channel',
        'username' => 'Horizon',
        'icon' => ':robot:',
    ],
],

With this setup, Horizon will send notifications to your Slack channel whenever a job fails, allowing you to take immediate action.

Conclusion

Laravel Horizon is an invaluable tool for managing and monitoring your queues. Its real-time dashboard and detailed metrics make it easier to ensure efficient job processing, making it a valuable asset for any Laravel developer. By integrating Horizon into your workflow, you can maintain a smooth operation of background tasks and quickly address any issues that arise.
