dogstatd-client

A java client to push UDP messages to a local dogstatd.

Javadoc and build reports are available.

Requirements

• Minimal latency in the mainline processing
• Some, but not extreme buffering of outgoing messages
• Non-blocking write of UDP message
• Thread-safe sender
• Lack of dogstatd collector will be noted, but not cause failure of mainline processing

Assumptions

• A local (on the same host) dogstatd collector
• Firing a UDP message per application event will be cheaper than in-process aggregation of events

Use with Maven

To include dogstatd-client in your maven build, use the following fragment in your pom.

      <dependency>
        <groupId>org.honton.chas</groupId>
        <artifactId>dogstatd-client</artifactId>
        <version>0.0.3</version>
      </dependency>

Typical Java Use

In setup code

  // you only need a single instance, Sender is thread safe and send method does not block caller
  static public final Sender METRICS = new Sender();

Sending some example metrics

  METRICS.send(new Histogram("histogram.name", latency);
  
  METRICS.send(new Gauge("round", i, tag));
  
  METRICS.send(new Counter("pi", 3.14));
  
  METRICS.send(new Event("title", "message", "tag1", "tag2"));

0.2 to 0.3

• Added public constructors for Event
• Added public constructors for ServiceCheck
• Metric changed to abstract
• Tags changed to package protected
• Validator changed to package protected
