Quickstart

Add the dependencies to your project

For Maven add to your pom.xml:

<dependencies>
  <dependency>
    <groupId>io.opencensus</groupId>
    <artifactId>opencensus-api</artifactId>
    <version>0.23.0</version>
  </dependency>
  <dependency>
    <groupId>io.opencensus</groupId>
    <artifactId>opencensus-exporter-trace-ocagent</artifactId>
    <version>0.23.0</version>
  </dependency>
  <dependency>
    <groupId>io.opencensus</groupId>
    <artifactId>opencensus-impl</artifactId>
    <version>0.23.0</version>
    <scope>runtime</scope>
  </dependency>
  <dependency>
    <groupId>io.netty</groupId>
    <artifactId>netty-tcnative-boringssl-static</artifactId>
    <version>0.23.0.Final</version>
    <scope>runtime</scope>
  </dependency>
</dependencies>

For Gradle add to your dependencies:

compile 'io.opencensus:opencensus-api:0.23.0'
compile 'io.opencensus:opencensus-exporter-trace-ocagent:0.23.0'
runtime 'io.opencensus:opencensus-impl:0.23.0'
runtime 'io.netty:netty-tcnative-boringssl-static:2.0.20.Final'

Register the exporter

public class MyMainClass {
  public static void main(String[] args) throws Exception {
    OcAgentTraceExporter.createAndRegister();
    // ...
  }
}

FAQ

Why is netty-tcnative-boringssl-static needed? Which version should I use?

It's because this artifact depends on grpc-netty which requires a runtime dependency on netty-tcnative-boringssl-static for it to work. For more details and a table of known working version combinations, see https://github.com/grpc/grpc-java/blob/master/SECURITY.md#netty.
