Dropwizard Zipkin Bundle

Build Status Maven Central GitHub license Become a Patron

A bundle for submitting tracing data to Zipkin from Dropwizard applications. Internally, this library uses Brave to interface a Zipkin collector.

Dependency Info

<dependency>
    <groupId>com.smoketurner.dropwizard</groupId>
    <artifactId>zipkin-core</artifactId>
    <version>2.0.7-1</version>
</dependency>

Beginning with v1.2.2-4, if you are using the Kafka sender, you must explicitly add the kafka-clients dependency into your pom.xml as it has been excluded from the zipkin-core module.

<dependency>
    <groupId>org.apache.kafka</groupId>
    <artifactId>kafka-clients</artifactId>
    <version>2.2.1</version>
</dependency>

Usage

Add a ZipkinBundle to your Application class.

private ZipkinBundle<HelloWorldConfiguration> zipkinBundle;

@Override
public void initialize(Bootstrap<HelloWorldConfiguration> bootstrap) {
  zipkinBundle = new ZipkinBundle<HelloWorldConfiguration>(getName()) {
    @Override
    public ZipkinFactory getZipkinFactory(HelloWorldConfiguration configuration) {
      return configuration.getZipkinFactory();
    }
  };
  bootstrap.addBundle(zipkinBundle);
}

@Override
public void run(HelloWorldConfiguration configuration, Environment environment) throws Exception {
  final Optional<HttpTracing> tracing = zipkinBundle.getHttpTracing();
}

Configuration

For configuring the Zipkin connection, there is a ZipkinFactory:

zipkin:

  # Required properties
  # Whether tracing is enabled or not (defaults to true)
  enabled: true
  # Listening IP address of the service
  serviceHost: 192.168.1.100
  # Listening port of the service
  servicePort: 8080

  # Optional properties
  # Span collector to use (console, http, kafka or empty)
  collector: http
  # If using the http collector, provide the baseUrl
  baseUrl: http://127.0.0.1:9411/
  # If using the http collector, timeout out when connecting (defaults to 10s)
  connectTimeout: 10s
  # If using the http collector, timeout out when reading the response (defaults to 60s)
  readTimeout: 60s
  # If using the kafka collector, provide the Kafka bootstrap servers
  bootstrapServers: 127.0.0.1:9092;10.0.1.1:9092

Example Application

This bundle includes a modified version of the HelloWorldApplication from Dropwizard's Getting Started documentation.

You can execute this application by first starting Zipkin on your local machine then running:

./mvnw clean package
java -jar zipkin-example/target/zipkin-example-*-SNAPSHOT.jar server zipkin-example/hello-world.yml

This will start the application on port 8080 (admin port 8180). This application demonstrations the following Zipkin integration points:

  • You can use the included ZipkinClientBuilder to construct an instrumented JerseyClient's that will send span traces to Zipkin
  • The service will send request and response traces to Zipkin
