statsd

This is a simple statsd module for Play! Framework 2.0. It pulls in configuration from conf/application.conf
and provides a singleton object Statsd with methods for counter and timing calls to statsd. It provides
both a Scala and Java interface. Similar to the Play 2.0 convention, the Scala interface is called
play.modules.statsd.api.Statsd, and the Java interface is play.modules.statsd.Statsd.

Getting started

To install, add "net.vz.play.statsd" %% "play-statsd" % "1.0.0-rc.1" to your dependencies, for example:

val appDendencies = Seq(@"net.vz.play.statsd" %% "play-statsd" % "1.0.0-rc.1")

Configuration

The following are configuration flags that belong in conf/application.conf:

• statsd.enabled: Should be true to use this module. Can be false for testing.
• statsd.stat.prefix: The prefix for all stats sent by this app. They will appear in a folder of the same name on graphite.
• statsd.host: The hostname of the statsd server.
• statsd.port: The port for the statsd server.

If there are any configuration problems (missing or unparseable settings), there will be a warning the first time the module is used but will not cause an error in your app.

Scala Usage

To use this module, first add this import:

import play.modules.statsd.api.Statsd

Now you can call it like this:

Statsd.increment("my.stat")  // Increment my.stat by 1
Statsd.increment("my.bigger.stat", value = 100)  // Increment my.bigger.stat by 100
Statsd.increment("my.frequent.stat", samplingRate = 0.1)  // Increment my.frequent.stat 10% of the time
Statsd.timing("my.operation", 100)  // my.operation took 100 ms
Statsd.timing("my.frequent.operation", 10, 0.5)  // my operation took 50 ms. Send this stat 50% of the time
Statsd.time("my.operation.i.dont.want.to.time.myself") {
  // do some stuff...
} // This will get timed automatically.
Statsd.gauge("my.value", 42)  // Record 42 for my.value

Any errors will be logged, but will not cause the app to fail.

Java Usage

To use this module, first add this import:

import play.modules.statsd.Statsd;

Now you can call it like this:

Statsd.increment("my.stat");  // Increment my.stat by 1
Statsd.increment("my.bigger.stat", 100);  // Increment my.bigger.stat by 100
Statsd.increment("my.frequent.stat", 0.1);  // Increment my.frequent.stat 10% of the time
Statsd.timing("my.operation", 100);  // my.operation took 100 ms
Statsd.timing("my.frequent.operation", 10, 0.5);  // my operation took 50 ms. Send this stat 50% of the time
String result = Statsd.time("my.operation.i.dont.want.to.time.myself", new F.Function0<String>() {
  public String apply() {
    return "some result";
  }}); // This will get timed automatically.
Statsd.gauge("my.value", 42L)  // Record 42 for my.value

Any errors will be logged, but will not cause the app to fail.
