Sending Metrics To Statsd With PHP

Someone has already created a popular PHP client library for interfacing with statsd that has over 1.5 million installs, so let's go ahead and pull that through composer.

composer require domnikl/statsd

Below is a simple script that will incerement a statistic. You might want run something like this on every request your web application gets so you can track how much traffic your sites are getting. It would also be a good idea to do it whenever your web application serves up any of the http error response codes, such as a 404.

<?php

require_once(__DIR__ . '/vendor/autoload.php');
define('GRAPHITE_SERVER_HOST', '10.2.0.70');
$connection = new \Domnikl\Statsd\Connection\UdpSocket(GRAPHITE_SERVER_HOST, 8125);
$statsd = new \Domnikl\Statsd\Client($connection, "test.namespace");

// the global namespace is prepended to every key (optional)
$statsd->setNamespace("test");

$statsd->increment("foo.bar");

Now if you execute that a couple of times and then head over to the your Graphite server you will be able to see the metrics by following the path shown.

As you can see, I executed the program 7 times at 19:40.
