Recently I wanted to install new relic in a Grails 3 app which I distribute through Elastic Beanstalk.
One of the steps described in the new relic documentation is:
In your WAR file, add the newrelic.jar and newrelic.yml files to WEB-INF/lib/.
How to do that in a Grails 3 application?
- Create a folder in the root folder of your application called newrelic
- Copy both files (newrelic.jar and newrelic.yml) to the previously created newrelic folder.
- Add the next snippet to your build.gradle file:
war {
from('newrelic') {
into 'WEB-INF/lib'
include 'newrelic.*'
}
}
Additionally you would probably want to add to the dependencies block in build.gradle the next line:
compile "org.grails.plugins:newrelic:3.19.2"
This will install the Grails newrelic Plugin to your grails app.
Among other things the plugin will insert an interceptor which names transactions based on your controller/action information.
NewRelicInterceptor – An interceptor matching all requests to automatically name transactions as {controllerName}/{actionName}.
We are done in the grails side, complete the installation guide and you will have new relic configured.

For the newrelic.jar and newrelic.yml here is another option that we use.
It will install/configure NewRelic app AND server monitoring on AWS ElasticBeanstalk.
It will also call the NewRelic deployment API each time you start a new env.
1- create a folder src/main/webapp/.ebextensions, a folder src/main/webapp/.ebextensions/files and add the newrelic.jar in it.
2- create a file src/main/webapp/.ebextensions/app.config
container_commands:
newrelic:
command: “bash -x .ebextensions/newrelic.sh”
3- create a file src/main/webapp/.ebextensions/newrelic.sh
#!/bin/sh
# New Relic (Application monitoring)
mkdir /var/lib/newrelic
mv ./.ebextensions/files/newrelic*.jar /var/lib/newrelic/
bash ./.ebextensions/files/newrelic.yml.sh > /var/lib/newrelic/newrelic.yml
# New Relic Agent (Server monitoring)
rpm -Uvh https://yum.newrelic.com/pub/newrelic/el5/x86_64/newrelic-repo-5-3.noarch.rpm
yum -y install newrelic-sysmond
/usr/sbin/nrsysmond-config –set license_key=$NR_LICENSE
/etc/init.d/newrelic-sysmond start
# New Relic deployment event
export AP_VERSION=`cat ./META-INF/grails.build.info | grep info.app.version | cut -d= -f2`
java -jar /var/lib/newrelic/newrelic.jar deployment –revision=$AP_VERSION
4- create a file src/main/webapp/.ebextensions/files/newrelic.yml.sh (to dynamically generate newrelic.yml based on env var)
cat << EOF
common: &default_settings
license_key: '$NR_LICENSE'
enable_auto_transaction_naming: false
app_name: $NR_APPNAME
EOF
Then, in your Beanstalk app config options, add "-javaagent:/var/lib/newrelic/newrelic.jar" to the JVM command line parameter and set NR_LICENSE and NR_APPNAME env properties.
Note: maybe, this is something I should add in the Grails Newrelic plugin README on Github :).
