java-dogstatsd-client

A statsd client library implemented in Java. Allows for Java applications to easily communicate with statsd.

This version is forked from the upstream java-dogstatsd-client project (which is, in turn, forked from java-statsd-client), adding additional support for DataDog extensions for use with dogstatsd.

See CHANGELOG.md for changes.

Downloads

The client jar is distributed via maven central, and can be downloaded here.

Usage

import com.timgroup.statsd.StatsDClient;
import com.timgroup.statsd.NonBlockingStatsDClient;

public class Foo {

  private static final StatsDClient statsd = new NonBlockingStatsDClient(
    "my.prefix",                          /* prefix to any stats; may be null or empty string */
    "statsd-host",                        /* common case: localhost */
    8125,                                 /* port */
    new String[] {"tag:value"}            /* DataDog extension: Constant tags, always applied */
  );

  public static final void main(String[] args) {
    statsd.incrementCounter("foo");
    statsd.recordGaugeValue("bar", 100);
    statsd.recordGaugeValue("baz", 0.01); /* DataDog extension: support for floating-point gauges */
    statsd.recordHistogram("qux", 15)     /* DataDog extension: histograms */
    statsd.recordHistogram("qux", 15.5)   /* ...also floating-point */

    ServiceCheck sc = new ServiceCheck("my.check.name", ServiceCheck.OK);
    statsd.serviceCheck(sc); /* Datadog extension: send service check status */

    /* Compatibility note: Unlike upstream statsd, DataDog expects execution times to be a
     * floating-point value in seconds, not a millisecond value. This library
     * does the conversion from ms to fractional seconds.
     */
    statsd.recordExecutionTime("bag", 25, "cluster:foo"); /* DataDog extension: cluster tag */
  }
}
