README

Background job and cron monitoring for Laravel. Monitors Horizon internals, queue depth, and cron health — things generic monitors can't see.

Cronitor tells you a job ran. Crontinel tells you your Horizon supervisor is paused.

What it monitors

Requirements

• PHP 8.2, 8.3, or 8.4
• Laravel 11, 12, or 13

Installation

composer require crontinel/laravel
php artisan crontinel:install

That's it. Visit /crontinel in your browser.

crontinel:install publishes the config file and runs the migration for the crontinel_runs table.

Cron run tracking is automatic — Crontinel listens to Laravel's ScheduledTaskFinished and ScheduledTaskFailed events. No wrapping or modification of your scheduled commands needed.

CLI health check

# Table output (human-readable)
php artisan crontinel:check

# JSON output (for CI/CD integration)
php artisan crontinel:check --format=json

# Check without firing alerts
php artisan crontinel:check --no-alerts

Exits with code 0 when all monitors are healthy, 1 if any alert is active. Use this in CI or monitoring pipelines.

Configuration

After install, edit config/crontinel.php:

return [
    // Dashboard URL path (default: /crontinel)
    'path' => env('CRONTINEL_PATH', 'crontinel'),

    // Dashboard middleware
    'middleware' => ['web', 'auth'],

    // Connect to Crontinel SaaS for multi-app hosted dashboards (optional)
    'saas_key' => env('CRONTINEL_API_KEY'),
    'saas_url' => env('CRONTINEL_API_URL', 'https://app.crontinel.com'),

    'horizon' => [
        'enabled'                          => true,
        'supervisor_alert_after_seconds'   => 60,
        'failed_jobs_per_minute_threshold' => 5,
        'connection'                       => 'horizon', // Redis connection name for Horizon
    ],

    'queues' => [
        'enabled'                 => true,
        'watch'                   => [],    // empty = auto-discover
        'depth_alert_threshold'   => 1000,
        'wait_time_alert_seconds' => 300,
    ],

    'cron' => [
        'enabled'                  => true,
        'late_alert_after_seconds' => 120,
        'retain_days'              => 30,
    ],

    'alerts' => [
        'channel' => env('CRONTINEL_ALERT_CHANNEL'), // 'slack' or 'mail'
        'mail'  => ['to' => env('CRONTINEL_ALERT_EMAIL')],
        'slack' => ['webhook_url' => env('CRONTINEL_SLACK_WEBHOOK')],
    ],
];

Environment variables

# Dashboard path (optional)
CRONTINEL_PATH=crontinel

# Alerts — set channel to 'slack' or 'mail'
CRONTINEL_ALERT_CHANNEL=slack
CRONTINEL_SLACK_WEBHOOK=https://hooks.slack.com/...
CRONTINEL_ALERT_EMAIL=ops@yourcompany.com

# SaaS reporting (optional)
CRONTINEL_API_KEY=your-api-key

Alerts

Crontinel fires alerts when:

• Horizon is stopped or paused
• A supervisor process goes down
• Failed jobs per minute exceeds threshold
• Queue depth or oldest job age exceeds threshold
• A scheduled command exits with non-zero code
• A scheduled command is late (missed its expected run window)

Alerts auto-resolve and send a "resolved" notification when the issue clears.

Alert deduplication: The same alert won't fire more than once per 5 minutes for the same issue.

Not using Horizon?

Set horizon.enabled = false in config. Queue and cron monitoring work independently of Horizon.
