README
⚠️ This repo is abandoned and will no longer be maintained. Please use slickdeals/statsd instead.
A PHP client library for the statistics daemon (statsd) intended to send metrics from PHP applications.
Installation
The best way to install statsd-php is to use Composer and add the following to your project's composer.json
file:
{ "require": { "domnikl/statsd": "~3.0" } }
Usage
<?php $connection = new \Domnikl\Statsd\Connection\UdpSocket('localhost', 8125); $statsd = new \Domnikl\Statsd\Client($connection, "test.namespace"); // the global namespace is prepended to every key (optional) $statsd->setNamespace("test"); // simple counts $statsd->increment("foo.bar"); $statsd->decrement("foo.bar"); $statsd->count("foo.bar", 1000);
When establishing the connection to statsd and sending metrics, errors will be suppressed to prevent your application from crashing.
If you run statsd in TCP mode, there is also a \Domnikl\Statsd\Connection\TcpSocket
adapter that works like the UdpSocket
except that it throws a \Domnikl\Statsd\Connection\TcpSocketException
if no connection could be established.
Please consider that unlike UDP, TCP is used for reliable networks and therefor exceptions (and errors) will not be suppressed in TCP mode.
Timings
<?php // timings $statsd->timing("foo.bar", 320); $statsd->time("foo.bar.bla", function() { // code to be measured goes here ... }); // more complex timings can be handled with startTiming() and endTiming() $statsd->startTiming("foo.bar"); // more complex code here ... $statsd->endTiming("foo.bar");
Memory profiling
<?php // memory profiling $statsd->startMemoryProfile('memory.foo'); // some complex code goes here ... $statsd->endMemoryProfile('memory.foo'); // report peak usage $statsd->memory('foo.memory_peak_usage');
Gauges
statsd supports gauges, arbitrary values which can be recorded.
This method accepts both absolute (3) and delta (+11) values.
NOTE: Negative values are treated as delta values, not absolute.
<?php // Absolute value $statsd->gauge('foobar', 3); // Pass delta values as a string. // Accepts both positive (+11) and negative (-4) delta values. $statsd->gauge('foobar', '+11');
Sets
statsd supports sets, so you can view the uniqueness of a given value.
<?php $statsd->set('userId', 1234);
disabling sending of metrics
To disable sending any metrics to the statsd server, you can use the Domnikl\Statsd\Connection\Blackhole
connection
class instead of the default socket abstraction. This may be incredibly useful for feature flags. Another options is
to use Domnikl\Statsd\Connection\InMemory
connection class, that will collect your messages but won't actually send them.
