Netuitive Dropwizard Integration

Dropwizard is part Java framework and part Java library that assists in operating web services. The Netuitive Dropwizard integration uses a DropWizard.io netuitive reporter to send metrics to Netuitive's Linux agent.

Using the DropWizard Integration

1. Include the appropriate Ananke library dependency. You'll also need a working StatsD (Netuitive StatsD or Etsy StatsD) integration.

2. Add dropwizard-metrics to your POM. There's also additional dependency formats for other build managers here.

    <dependency>
      <groupId>com.netuitive</groupId>
      <artifactId>dropwizard-metrics</artifactId>
      <version>1.0.0</version>
      <type>pom</type>
    </dependency>
   

3. Add the following to your Dropwizard config.yml file:

    metrics:
      frequency: 1 minute
      reporters:
          - type: netuitive
            host: netuitive-agent
            port: 8125
   

Testing with Docker Stack

Runtime Environment Used for Testing

• Docker version 1.10.3, build 20f81dd
• docker-compose version 1.6.2, build 4d72027
• VirtualBox Version 5.0.16 r105871

Docker Stack Defines Two Containers:

• dropwizard
  • Example Dropwizard application with dropwizard-metrics-netuitive reporter (requires local gradle install to work).
  • Updated config.yml file to enable netuitive reporter.
• netuitive-agent
  • Docker Linux agent to ship data to Netuitive. Note: some environment variables need to be updated to configure the agent.

Starting the Example Docker Environment

1. Run the following to start the example application and Netuitive Docker agent:

    docker-compose up -d
   

Docker will build the dropwizard-metrics and example project within the container from source and run the Netuitive Docker agent alongside it.

Running the tests

1. Change to the test docker directory, which contains a test stack definition for testing.

    cd src/test/docker;
   

2. In that directory run:

    docker-compose up -d --build
   

3. Now create and run your tests:

    ./run_tests.sh
   

4. Now shut down the stack:

    docker-compose stop
