Dropwizard Metrics for Akka Actors

build status

This project instruments an Akka ActorSystem to provide Dropwizard metrics for Actors. Currently, the following metrics are captured:

  • A Gauge for the size of an Actors mailbox
  • A Timer measuring how long a message sits in an Actors mailbox

Usage

This project is composed of two modules:

  • akka-dropwizard-agent, a java agent which performs the ActorSystem instrumentation
  • akka-dropwizard-metrics which contains the code to configure the agent.

First, include the akka-dropwizard-metrics module in your project:

    <dependency>
        <groupId>com.github.kevinconaway</groupId>
        <artifactId>akka-dropwizard-metrics</artifactId>
        <version>1.2</version>
    </dependency>

There is a singleton configuration class, AkkaDropwizard that must be configured before the ActorSystem is created

MetricRegistry registry = ...
AkkaDropwizard.configure(registry);

By default, the metrics will be stored under a root prefix called actor-metrics. You can customize this by providing an instance of AkkaDropwizardSettings to AkkaDropwizard

AkkaDropwizardSettings settings = ...
MetricRegistry registry = ...
AkkaDropwizard.configure(registry, settings);

The instrumentation is performed by a java agent that you need to run with your application. Add the following argument to your VM startup properties:

-javaagent:/path/to/akka-dropwizard-agent-1.2.jar
