An overview of the Java APM installation process

Our Java APM agent auto-instruments your code so you can start monitoring applications. Read this for an overview of the generic APM installation process. For more specific instructions, use monitor your Java app to find the specific resource for your Java app configuration.

1. Prepare to install

Check the following:

When you're ready, use the guided installation for an automated install. If you're in the EU, select that option. Or for a manual approach, follow the instructions in this document to complete a basic Java agent installation. Either way, you need a New Relic account. (It's free, forever.)

Get an account

2. Get the agent

Download newrelic-java.zip using curl, Invoke-WebRequest (PowerShell), or the New Relic UI:

3. Configure the agent

Here's how to do a basic setup with agent configuration settings in newrelic.yml.

Tip

For an advanced installation, you can pass settings with environment variables, Java system properties, or server-side configuration. To understand the precedence of these configuration settings, see Java agent configuration: Config file.

The Java agent requires the license_key and app_name settings at startup. All the other settings are optional, and you can review them in Java agent configuration: Config file.

Go to the unzipped installation file, and inside the newrelic subdirectory, edit newrelic.yml:

  1. Find the line with license_key.

  2. Replace '<%= license_key %>' with your license. For example:

    license_key: 456n20n1367ov2s174v51nvn789d21s67v26NRAL
  3. Find the line with app_name.

  4. Replace My Application with a name that helps you identify the application. For example:

    app_name: Tax Calculator

    Tip

    If you need tips about how to name your application, see Name your application.

  5. Add optional settings that you want, such as agent logging and distributed tracing (or add them later).

  6. Save and close newrelic.yml.

4. Install the agent

The Java agent installation involves copying all the unzipped New Relic files into the directory structure of your application server/container. For example, you can create a /opt/newrelic directory, but if you want to put the files elsewhere, make sure of the following:

  • The .jar files in the directory cannot be on the classpath.
  • The .jar files cannot be in directories specified in java.endorsed.dirs.

To install the Java agent:

  1. In your application server/container directory structure, create a directory for New Relic files (for example, /opt/newrelic).

  2. Copy all the New Relic files from your unzipped newrelic directory into your new directory.

  3. Make sure that your application server/container includes this option when it starts Java (for tips on how to do this with your tool or framework, see JVM arguments):

    -javaagent:/full/path/to/newrelic.jar
  4. Start or restart your application server/container.

Generate some traffic for your app, and then wait a few minutes for data to appear in the APM Summary page. If nothing appears, follow the troubleshooting procedures.

5. Post-installation tasks

If you are using newrelic.yml to make configuration settings, consider the following:

  • We recommend you change the default newrelic.yml file permissions to read/write only for the owner of the application server process.
  • As you would with other important files, be sure newrelic.yml is part of your backup routine.
  • We recommend using New Relic Diagnostics to validate your settings, either before or after you deploy.

View logs for your APM and infrastructure data

You can also bring your logs and application's data together to make troubleshooting easier and faster. With logs in context, you can see log messages related to your errors and traces directly in your app's UI. You can also see logs in context of your infrastructure data, such as Kubernetes clusters. No need to switch to another page in the New Relic UI.
