2 Prerequisite

Before starting with this how-to, make sure you have completed the following prerequisite:

3 Setting Up

In this section, we will walk through all the steps to configure New Relic so that it can be used for application performance monitoring of your Mendix application.

3.1 Setting up New Relic (On-Premises Only)

The following steps are only relevant for on-premises deployments (skip to 2.2.1 Cloud Foundry if you are deploying your Mendix application to Cloud Foundry).

  1. Log in to New Relic and create a new application:

  2. Select Java:

  3. Download the Java agent archive and save your license key:

  4. Add your license key to the newrelic.yml file from the downloaded archive as described here: https://docs.newrelic.com/docs/agents/java-agent/installation/java-agent-manual-installation#h2-download-files.

3.2 Setting Up Your Mendix Deployment

3.2.1 Cloud Foundry

Follow these build pack instructions to set up New Relic for Cloud Foundry deployments: https://github.com/mendix/cf-mendix-buildpack#new-relic.

3.2.2 On Premise Linux & Windows Service Console

To the javaopts list in your m2ee.yaml file, add “-javaagent:javaagent.jar”. For example:

 javaopts: [
   "-Dfile.encoding=UTF-8", "-XX:MaxPermSize=128M", "-Xmx512M", "-Xms512M",
   "-Djava.io.tmpdir=/srv/mendix/data/tmp",
   "-javaagent:/opt/newrelic/javaagent.jar"
 ]

3.2.3 Mendix Modeler (Development Mode Only)

  1. Open your Mendix application, and click on Settings in the Project Explorer:

  2. Open a configuration:

  3. In the Extra JVM parameters field on the Server tab, add “-javaagent:javaagent.jar”:
