Set up the New Relic agent Anchor to this heading

To set up New Relic in the Java project, we have two ways:

  • Using the Maven project
  • Download the code through .platform.app.yaml.

Using Maven Anchor to this heading

This section explains how to configure Maven to download and unzip the newrelic-java.zip file, which contains all New Relic Java agent components.

Configure your pom.xml to download newrelic-java.zip:

<dependency>
  <groupId>com.newrelic.agent.java</groupId>
  <artifactId>newrelic-java</artifactId>
    <version>JAVA_AGENT_VERSION</version>
  <scope>provided</scope>
  <type>zip</type>
</dependency>

Replace JAVA_AGENT_VERSION with the latest Java agent version 1.

Unzip newrelic-java.zip by configuring maven-dependency-plugin in your pom.xml:

    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-dependency-plugin</artifactId>
      <version>3.1.1</version>
      <executions>
        <execution>
          <id>unpack-newrelic</id>
          <phase>package</phase>
          <goals>
            <goal>unpack-dependencies</goal>
          </goals>
          <configuration>
            <includeGroupIds>com.newrelic.agent.java</includeGroupIds>
            <includeArtifactIds>newrelic-java</includeArtifactIds>
            <excludes>**/newrelic.yml</excludes>
            <overWriteReleases>false</overWriteReleases>
            <overWriteSnapshots>false</overWriteSnapshots>
            <overWriteIfNewer>true</overWriteIfNewer>
            <outputDirectory>${project.build.directory}</outputDirectory>
          </configuration>
        </execution>
      </executions>
    </plugin>

The next step is to configure your app to set the agent in the JVM parameters:

name: app
type: 'java:8'
disk: 1024

hooks:
    build: |
        mvn clean package
        rm -rf newrelic/
        mv target/newrelic/ newrelic/        

web:
    commands:
        start: |
            java -jar \
            -Xmx$(jq .info.limits.memory /run/config.json)m -XX:+ExitOnOutOfMemoryError \
            -javaagent:/app/newrelic/newrelic.jar            

Manual Configuration Anchor to this heading

To use this installation it is only required that you modify .platform.app.yaml, which will download and set the New Relic Java agent for you.

name: app
type: 'java:8'
disk: 1024

variables:
    env:
        NEW_RELIC_URL: https://download.newrelic.com/newrelic/java-agent/newrelic-agent/current/newrelic-java.zip

hooks:
    build: |
        mvn clean package
        rm -rf newrelic
        curl -O $NEW_RELIC_URL
        unzip newrelic-java.zip        

web:
    commands:
        start: |
            java -jar \
            -Xmx$(jq .info.limits.memory /run/config.json)m \
            -XX:+ExitOnOutOfMemoryError \
            -javaagent:/app/newrelic/newrelic.jar            

You need to wait a bit for your New Relic dashboard to be generated.
