Framework-agnostic PHP core for [Crontinel](https://crontinel.com). Provides monitor contracts, typed data objects, alert management with deduplication, and cron expression helpers.

**If you use Laravel, install [`crontinel/laravel`](https://github.com/crontinel/crontinel) instead.** It pulls in this package automatically and adds service providers, dashboard, Artisan commands, and event listeners.

Install `crontinel/php` directly when you are:

- Building an adapter for Symfony, Slim, or another framework
- Integrating Crontinel into a vanilla PHP application
- Writing a custom monitor that does not depend on Laravel

---

Requirements
------------

[](#requirements)

- PHP 8.2, 8.3, or 8.4
- Composer

Compatibility
-------------

[](#compatibility)

- **Laravel 10, 11, and 12** — install [`crontinel/laravel`](https://github.com/crontinel/crontinel) instead, which wraps this package and adds Laravel-specific integration.
- **Horizon** — this package reads the same Redis keys that Horizon uses. When you install `crontinel/laravel`, the `HorizonMonitor` works out of the box with no additional configuration.
- **Other frameworks** — Symfony, Slim, and any PHP 8.2+ application can use the contracts and data objects directly.

---

Installation
------------

[](#installation)

```
composer require crontinel/php
```

---

What this package provides
--------------------------

[](#what-this-package-provides)

### Contracts

[](#contracts)

- **`MonitorInterface`** -- implement `isHealthy(): bool` to create a custom monitor
- **`AlertChannelInterface`** -- implement `send(AlertEvent $event): void` to deliver alerts via any transport (Slack, email, webhook, etc.)

### Data objects

[](#data-objects)

Immutable, readonly value objects used across the stack:

- **`AlertEvent`** -- key, title, message, level (`critical` / `warning` / `info` / `resolved`), fired timestamp
- **`CronStatus`** -- command, expression, status, last run metadata, next due time
- **`HorizonStatus`** -- Horizon supervisor state
- **`QueueStatus`** -- queue depth, failed count, oldest job age

### Alert management

[](#alert-management)

**`AlertManager`** handles fire/resolve lifecycle with built-in deduplication. It accepts any PSR-16 cache and any `AlertChannelInterface` implementation:

- Deduplicates repeated alerts for the same key (default: 5 min TTL)
- Auto-sends "resolved" notifications when an issue clears
- Logs failures via PSR-3 logger (falls back to `NullLogger`)

### Cron expression helpers

[](#cron-expression-helpers)

**`CronExpressionHelper`** wraps `dragonmantank/cron-expression` with convenience methods:

- `nextDue(string $expression)` -- next scheduled run as `DateTimeImmutable`
- `previousDue(string $expression)` -- last scheduled run
- `isLate(DateTimeInterface $lastRunAt, string $expression, int $graceSeconds = 120)` -- whether a job has missed its window

### Built-in monitors

[](#built-in-monitors)

Ready-to-use monitor implementations (all implement `MonitorInterface`):

- `CronMonitor`, `HorizonMonitor`, `QueueMonitor`

---

Usage example
-------------

[](#usage-example)

Implement `MonitorInterface` to build a custom health check:

```
use Crontinel\Contracts\MonitorInterface;

final class DiskSpaceMonitor implements MonitorInterface
{
    public function __construct(
        private readonly string $path = '/',
        private readonly float $minFreePercent = 10.0,
    ) {}

    public function isHealthy(): bool
    {
        $free = disk_free_space($this->path);
        $total = disk_total_space($this->path);

        return ($free / $total) * 100 >= $this->minFreePercent;
    }
}
```

Wire up alert delivery by implementing `AlertChannelInterface`:

```
use Crontinel\Contracts\AlertChannelInterface;
use Crontinel\Data\AlertEvent;

final class WebhookChannel implements AlertChannelInterface
{
    public function __construct(
        private readonly string $url,
    ) {}

    public function send(AlertEvent $event): void
    {
        file_get_contents($this->url, false, stream_context_create([
            'http' => [
                'method' => 'POST',
                'header' => 'Content-Type: application/json',
                'content' => json_encode([
                    'key'      => $event->key,
                    'title'    => $event->title,
                    'message'  => $event->message,
                    'level'    => $event->level,
                    'resolved' => $event->resolved,
                ]),
            ],
        ]));
    }
}
```

Then use `AlertManager` to fire and resolve alerts:

```
use Crontinel\Alert\AlertManager;

// Requires any PSR-16 cache implementation
$alertManager = new AlertManager(
    cache: $cache,
    channel: new WebhookChannel('https://example.com/webhook'),
);

$monitor = new DiskSpaceMonitor('/data');

if (! $monitor->isHealthy()) {
    $alertManager->fire('disk.data', 'Low disk space', 'Disk /data is below 10% free', 'critical');
} else {
    $alertManager->resolve('disk.data');
}
```

### Using CronExpressionHelper

[](#using-cronexpressionhelper)

```
use Crontinel\Cron\CronExpressionHelper;

$helper = new CronExpressionHelper();

// When is the next run of "every minute"?
$next = $helper->nextDue('* * * * *');
echo $next->format('Y-m-d H:i:s');

// Is a job that's been silent for 10 minutes late for a 5-minute schedule?
$lastRun = new \DateTimeImmutable('2026-04-11 10:50:00');
$isLate = $helper->isLate($lastRun, '*/5 * * * *', graceSeconds: 60);
// Returns true if current time exceeds $lastRun + 5min + 60s grace
```

### Using built-in monitors with AlertManager

[](#using-built-in-monitors-with-alertmanager)

```
use Crontinel\Alert\AlertManager;
use Crontinel\Monitors\QueueMonitor;

$alertManager = new AlertManager(
    cache: $cache,
    channel: new WebhookChannel('https://example.com/alerts'),
);

$queueMonitor = new QueueMonitor(
    redisConnection: 'default',
    maxDepth: 100,
    maxFailed: 10,
);

if (! $queueMonitor->isHealthy()) {
    $status = $queueMonitor->getStatus(); // returns QueueStatus object
    $alertManager->fire(
        'queue.depth',
        'Queue depth exceeded',
        "Queue has {$status->depth} jobs (max: 100)",
        'warning',
    );
}
```
