README

Send statistics to the statsd daemon over UDP.

This class generally follows the official php-example from Etsy, but moves the configuration options into the main class with reasonable defaults. This should make incorporation into framework-based applications more straightforward.

Installation

Installation is via composer:

composer require stevenscg/statsd-php

Configuration

The library can be configured by calling StatsD::config($params).

$params is an array that supports the following keys:

enabled - boolean - Set to false to disable UDP transmission (default: true)

prefix - string - Apply a global namespace to all metrics from this application

host - string - Hostname or IP of your carbon/graphite server

port - integer - StatsD port of your carbon/graphite server

The library can also be configured via environment variables:

STATSD_ENABLED - A boolean-like string (i.e. true, false, 1, 0)

STATSD_PREFIX - string

STATSD_ADDR - string - Example: 127.0.0.1:8125

StatsD Data Types and Class Methods

• Counting - increment and decrement

• Timing - timing

• Sampling - supported via "sampleRate" parameter on increment and decrement

• Gauges - gauge

• Sets - set

Usage

All methods are declared as static as they were in the upstream project.

Incrementing a counter is as simple as:

StatsD::increment("api.requests");

Example: Tracking logins and failures

function login() {
  ...
  if (!$this->Auth->login()) {
    StatsD::increment("logins.failed");
    return;
  }
  StatsD::increment("logins.ok");
  ...
}
