Installation
Composer
composer require triadev/laravel-prometheus-exporter
Application
The package is registered through the package discovery of laravel and Composer.
Once installed you can now publish your config file and set your correct configuration for using the package.
php artisan vendor:publish --provider="Triadev\PrometheusExporter\Provider\PrometheusExporterServiceProvider" --tag="config"
This will create a file config/prometheus-exporter.php.
Configuration
buckets_per_route
'buckets_per_route' => [
ROUTE-NAME => [10,20,50,100,200],
...
]
Usage
Get metrics
Laravel
When you are using laravel you can use the default http endpoint:
triadev/pe/metrics
Of course you can also register your own route. Here is an example:
Route::get(
ROUTE,
\Triadev\PrometheusExporter\Controller\LaravelController::class . '@metrics'
);
Lumen
When you are using lumen you must register the route on your own. Here is an example:
Route::get(
ROUTE,
\Triadev\PrometheusExporter\Controller\LumenController::class . '@metrics'
);
Middleware
RequestPerRoute
A middleware to build metrics for "request_total" and "requests_latency_milliseconds" per route.
Alias
lpe.requestPerRoute
Metrics
- requests_total (inc)
- requests_latency_milliseconds (histogram)
Example
$router->get('/test/route', function () { return 'valid'; })->middleware('lpe.requestPerRoute');
app_requests_latency_milliseconds_bucket{route="/test/route",method="GET",status_code="200",le="0.005"} 0 ... app_requests_latency_milliseconds_count{route="/test/route",method="GET",status_code="200"} 1 app_requests_latency_milliseconds_sum{route="/test/route",method="GET",status_code="200"} 6 app_requests_total{route="/test/route",method="GET",status_code="200"} 1
Roadmap
- histogram buckets per route (RequestPerRoute)
