🚀 Installation

You can install the package via composer:

composer require renoki-co/octane-exporter

In case you haven't published your Octane settings, do so:

php artisan octane:install

Next up, add the following Octane tables in your config/octane.php. These tables will be used to keep track of stats for the events:

return [

    'tables' => [
        'octane_exporter_requests:1' => [
            'total_count' => 'int',
            '2xx_count' => 'int',
            '3xx_count' => 'int',
            '4xx_count' => 'int',
            '5xx_count' => 'int',
        ],
        'octane_exporter_tasks:1' => [
            'total_count' => 'int',
            'active_count' => 'int',
        ],
        'octane_exporter_workers:1' => [
            'active_count' => 'int',
        ],
        'octane_exporter_ticks:1' => [
            'total_count' => 'int',
            'active_count' => 'int',
        ],

        // ...
    ],

];

The final step is to add the following listeners after the already existent ones in config/octane.php:

return [

    'listeners' => [
        WorkerStarting::class => [
            // ...
            \RenokiCo\OctaneExporter\Listeners\TrackStartedWorkers::class,
        ],

        RequestTerminated::class => [
            // ...
            \RenokiCo\OctaneExporter\Listeners\TrackTerminatedRequests::class,
        ],

        TaskReceived::class => [
            // ...
            \RenokiCo\OctaneExporter\Listeners\TrackReceivedTasks::class,
        ],

        TaskTerminated::class => [
            // ...
            \RenokiCo\OctaneExporter\Listeners\TrackTerminatedTasks::class,
        ],

        TickReceived::class => [
            // ...
            \RenokiCo\OctaneExporter\Listeners\TrackReceivedTicks::class,
        ],

        TickTerminated::class => [
            // ...
            \RenokiCo\OctaneExporter\Listeners\TrackTerminatedTicks::class,
        ],

        WorkerStopping::class => [
            // ...
            \RenokiCo\OctaneExporter\Listeners\TrackStoppedWorkers::class,
        ],
    ],

];

🙌 Usage

This package is pretty straightforward. Upon installing it, it will register the route at /exporter/group/octane-metrics and you can point Prometheus towards it for scraping.

scrape_configs:
  - job_name: 'octane'
    metrics_path: '/exporter/group/octane-metrics'
    scrape_interval: 5
    static_configs:
      - targets: ['localhost:8000']
        labels:
          app: 'my-octane-app'

Please keep in mind that the metrics are calculated by-process. Point your Prometheus scraper to all instances that run the Octane start command.
