README
A better Prometheus library for PHP applications.
Offers a modern, clean PHP 8.1 API, with support for default label values, based on and compatible with the original promphp/prometheus_client_php
library.
Installation
composer require danog/better-prometheus
Usage
<?php require 'vendor/autoload.php'; use danog\BetterPrometheus\BetterCollectorRegistry; use Prometheus\Storage\InMemory; use Prometheus\Storage\Redis; $adapter = new InMemory; // Any other promphp adapter may also be used... // $adapter = new Redis(); $registry = new BetterCollectorRegistry($adapter); // Note the difference with promphp: the labels are keys => values, not just keys. $counter = $registry->getOrRegisterCounter( 'test', 'some_counter', 'it increases', // Note: these are default label key+values, they will be sent verbatim, no changes ['someLabel' => 'defaultValue'] ); // Specify some additional labels post-construction like this (both keys and values)... $counter->incBy(3, ['type' => 'blue']); // ...or add some more default labels to the counter, creating a new counter: $newCounter = $counter->addLabels(['someOtherLabel' => 'someOtherDefaultValue']); assert($newCounter !== $counter); // true $newCounter->incBy(3, ['type' => 'blue']); // Gauges can also be used $gauge = $registry->getOrRegisterGauge( 'test', 'some_gauge', 'it sets', ['someLabel' => 'defaultValue'] ); $gauge->set(2.5, ['type' => 'blue']); // As well as histograms $histogram = $registry->getOrRegisterHistogram( 'test', 'some_histogram', 'it observes', ['someLabel' => 'defaultValue'], // [0.1, 1, 2, 3.5, 4, 5, 6, 7, 8, 9] ); $histogram->observe(3.5, ['type' => 'blue']); // And suummaries $summary = $registry->getOrRegisterSummary( 'test', 'some_summary', 'it observes a sliding window', ['someLabel' => 'defaultValue'], // 84600, // [0.01, 0.05, 0.5, 0.95, 0.99] ); $summary->observe(5, ['type' => 'blue']);
