This package ships with an in-memory registry that can be created using the Factory:
<?php
declare(strict_types=1);
use WyriHaximus\Metrics\Factory;
require 'vendor/autoload.php';
$registry = Factory::create();From there it supports 3 types of metrics; counters, gauges, and histograms. Ach of them has to have at least
one label. For example for a counter:
<?php
declare(strict_types=1);
use WyriHaximus\Metrics\Factory;
use WyriHaximus\Metrics\Label\Name;
require 'vendor/autoload.php';
$registry = Factory::create();
$counter = $registry->counter('name', 'description', new Name('label'));Once the metric collection has been create you can create a metric for the counter with specific values for the required labels:
<?php
declare(strict_types=1);
use WyriHaximus\Metrics\Factory;
use WyriHaximus\Metrics\Label;
use WyriHaximus\Metrics\Label\Name;
require 'vendor/autoload.php';
$registry = Factory::create();
$counterCollection = $registry->counter('name', 'description', new Name('label'));
$counter = $counterCollection->counter(new Label('label', 'value'));With the metric we have now we can operate on it, in the cause of the counter we can increase it:
<?php
declare(strict_types=1);
use WyriHaximus\Metrics\Factory;
use WyriHaximus\Metrics\Label;
use WyriHaximus\Metrics\Label\Name;
require 'vendor/autoload.php';
$registry = Factory::create();
$counterCollection = $registry->counter('name', 'description', new Name('label'));
$counter = $counterCollection->counter(new Label('label', 'value'));
$counter->incr();There is a full example in the examples directory that also includes gauges and histograms.
