README

Originally, this is a fork of traum-ferienwohnungen/laravel-prometheus-exporter with updated dependencies. Main goal of this work is to make the lib compatible with Laravel 7 and Lumen 7 running on PHP 7.4.

However, with the need to support guzzlehttp/guzzle 7, dependency was replaced with PromPHP/prometheus_client_php.

Description

A prometheus exporter for the Laravel and the Lumen web framework.

It tracks latency and request counts by request method, route path and response code.

Installation

composer require gorerider/laravel-prometheus-exporter

Adapters

Then choose from three storage adapters: Memory (default), APCu and Redis can also be used.

APCu

Ensure apcu-bc is installed and enabled. If you're using the official PHP docker hub non-alpine image, have a look in the Dockerfile on how to install.

Redis

Ensure php redis is installed and enabled. If you're using the official PHP docker hub non-alpine image, have a look in the Dockerfile on how to install.

By default, it looks for a redis server at localhost:6379. The server can be configured in config/prometheus_exporter.php.

Laravel

If you're requiring this package in Laravel, middleware and route will be configured for you automatically.

Enable the Service Provider

In config/app.php (if not already there):

'providers' => [
    ...
    /*
     * Package Service Providers...
     */
    gorerider\PrometheusExporter\Providers\LaravelServiceProvider::class,
    ...
]

Lumen

Register the ServiceProvider

In bootstrap/app.php

$app->register(gorerider\PrometheusExporter\Providers\LumenServiceProvider::class);

Add an endpoint for the metrics

In bootstrap/app.php

$app->router->get('/metrics', [
    'as' => 'metrics',
    'uses' => 'gorerider\PrometheusExporter\Controllers\LumenMetricsController@metrics',
]);

Configuration

Metrics are exposed on /metrics endpoint, e.g. http://my-service.com/metrics

The configuration can be found in config/prometheus_exporter.php.

All values can be configured via .env or environment variables.

Collectibles

If you want to disable any collectibles, you'll need to remove entries from the prometheus_exporter.php config.

Laravel

Run

php artisan vendor:publish

Finally, remove collectibles in app/config/prometheus_exporter.php

Lumen

Copy src/config/prometheus_exporter.php in this repo and add to your Lumen project in the config directory.

Finally, remove collectibles in app/config/prometheus_exporter.php
