Metrics

Simple library that abstracts different metrics collectors. I find this necessary to have a consistent and simple metrics API that doesn't cause vendor lock-in.

It also ships with a Symfony Bundle. This is not a library for displaying metrics.

Currently supported backends:

  • Doctrine DBAL
  • Graphite
  • Librato
  • Logger (Psr\Log\LoggerInterface)
  • Null (Dummy that does nothing)
  • StatsD
  • Zabbix

Installation

Using Composer:

composer require beberlei/metrics

API

You can instantiate clients:

<?php

$collector = \Beberlei\Metrics\Factory::create('statsd');

You can measure stats:

<?php

$collector->increment('foo.bar');
$collector->decrement('foo.bar');

$start = microtime(true);
$diff  = microtime(true) - $start;
$collector->timing('foo.bar', $diff);

$value = 1234;
$collector->measure('foo.bar', $value);

Some backends defer sending and aggregate all information, make sure to call flush:

<?php

$collector->flush();

Configuration

<?php
$statsd = \Beberlei\Metrics\Factory::create('statsd');

$zabbix = \Beberlei\Metrics\Factory::create('zabbix', array(
    'hostname' => 'foo.beberlei.de',
    'server'   => 'localhost',
    'port'     => 10051,
));

$zabbixConfig = \Beberlei\Metrics\Factory::create('zabbix_file', array(
    'hostname' => 'foo.beberlei.de',
    'file'     => '/etc/zabbix/zabbix_agentd.conf'
));

$librato = \Beberlei\Metrics\Factory::create('librato', array(
    'hostname' => 'foo.beberlei.de',
    'username' => 'foo',
    'password' => 'bar',
));

$null = \Beberlei\Metrics\Factory::create('null');

Symfony Bundle Integration

Register Bundle into Kernel:

<?php

class AppKernel extends Kernel
{
    public function registerBundles()
    {
        //..
        $bundles[] = new \Beberlei\Bundle\MetricsBundle\BeberleiMetricsBundle();
        //..
    }
}

Do Configuration:

# app/config/config.yml
beberlei_metrics:
    default: foo
    collectors:
        foo:
            type: statsd
        bar:
            type: zabbix
            prefix: foo.beberlei.de
            host: localhost
            port: 10051
        baz:
            type: zabbix_file
            prefix: foo.beberlei.de
            file: /etc/zabbix/zabbix_agentd.conf
        librato:
            type: librato
            username: foo
            password: bar
        dbal:
            type: doctrine_dbal
            connection: metrics # using the connection named "metrics"
        monolog:
            type: monolog

This adds collectors to the Metrics registry. The functions are automatically included in the Bundle class so that in your code you can just start using the convenient functions. Metrics are also added as services:

<?php

$metrics = $container->get('beberlei_metrics.collector.foo');

and the default collector can be fetched:

<?php

$metrics = $container->get('beberlei_metrics.collector');
