Quickstart

<?php

use Krenor\Prometheus\Metrics\Metric;
use Krenor\Prometheus\Metrics\Counter;
use Krenor\Prometheus\CollectorRegistry;
use Krenor\Prometheus\Renderer\TextRenderer;
use Krenor\Prometheus\Storage\StorageManager;
use Krenor\Prometheus\Storage\Repositories\InMemoryRepository;
use Krenor\Prometheus\Tests\Stubs\MultipleLabelsCounterStub as ExampleCounter;

Metric::storeUsing(new StorageManager(new InMemoryRepository));

$registry = new CollectorRegistry;

$counter = $registry->register(new ExampleCounter);

$counter->increment(['some', 'label', 'values']);
$counter->incrementBy(3, ['foo', 'bar', 'baz']);

$samples = $registry->collect();
$metrics = (new TextRenderer)->render($samples);
