A prometheus push gateway client library written in PHP

This package provides an easy PHP API for Prometheus Push Gateway. It was part of promphp/prometheus_client_php and was moved into a seperate package as of Prometheus Client PHP Version 2.0.0.

How does it work?

The PushGateway allows Prometheus to get Metrics from Systems that are not scrableable (Your Prometheus cannot access that systems). With this library you can easily send your metrics to the PushGateway.

Installation

Add as Composer dependency:

composer require promphp/prometheus_push_gateway_php

Usage

Let's assume you have that simple counter and want to send it to your PushGateway.

\Prometheus\CollectorRegistry::getDefault()
    ->getOrRegisterCounter('', 'some_quick_counter', 'just a quick measurement')
    ->inc();

// Now send it to the PushGateway:
$pushGateway = new \PrometheusPushGateway\PushGateway('http://192.168.59.100:9091');
$pushGateway->push(\Prometheus\CollectorRegistry::getDefault(), 'my_job', ['instance' => 'foo']);

Also look at the examples.
