This package is a wrapper bridging [jimdo/prometheus_client_php](https://github.com/Jimdo/prometheus_client_php) into Laravel.

## Installation

```bash
composer require superbalist/laravel-prometheus-exporter
```

Register the service provider in app.php
```php
'providers' => [
    // ...
    Superbalist\LaravelPrometheusExporter\PrometheusServiceProvider::class,
]
```

Register the facade in app.php
```php
'aliases' => [
    // ...
    'PubSub' => Superbalist\LaravelPrometheusExporter\PrometheusFacade::class,
]
```

## Configuration

The package has a default configuration which uses the following environment variables.
```
PROMETHEUS_NAMESPACE=app

PROMETHEUS_METRICS_ROUTE_ENABLED=true
PROMETHEUS_METRICS_ROUTE_PATH=metrics
PROMETHEUS_METRICS_ROUTE_MIDDLEWARE=null

PROMETHEUS_STORAGE_ADAPTER=memory
