This document explains the steps taken to implement New relic and AWS infra monitoring on prod2 resources.

New relic instructions

For setting up in ECS:

• Download the new relic java agent zip file and extract it from the new relic docs : https://docs.newrelic.com/docs/agents/java-agent/installation/install-java-agent

• configure the agent with newrelic.yml file and add the add the license key and app name as per the instructions in the above link.

• Place the new relic folder inside the docker folder.

• Copy the new relic in to the app.Dockerfile by adding the following lines.

...

-javaagent:/full/path/to/newrelic.jar

AWS Cloudwatch agent setup for infrastructure monitoring:

For setting up cloudwatch agent:

• SSH into the instance.

• Download the cloudwatch agent according to the platform from the link below link

  • https://docs.aws.amazon.com/

  AmazonCloudWatch

  • AWSEC2/latest/

  monitoring

  • UserGuide/

  download-cloudwatch-agent-commandline

  • mon-scripts.html

• Download and install the perl modules.

• Download and Install the packagemonitoring script.

#If#To itsdownload anthe RPMcloudwatch packagescript
sudo rpm -U ./amazon-cloudwatch-agent.rpm

#If its an DEB package
sudo dpkg -i -E ./amazon-cloudwatch-agent.deb

...

Once the agent is downloaded we can create and modify the configuration file.

...

curl https://aws-cloudwatch.s3.amazonaws.com/downloads/CloudWatchMonitoringScripts-1.2.2.zip -O

#Install the scripts
unzip CloudWatchMonitoringScripts-1.2.2.zip && \
rm CloudWatchMonitoringScripts-1.2.2.zip && \
cd aws-scripts-mon

• Create a cronjob to make the script run for every 5 minutes

crontab -e
#Add the line to the crontab
*/5 * * * * ~/aws-scripts-mon/mon-put-instance-data.pl --mem-used-incl-cache-buff --mem-util --disk-space-util --disk-path=/ --from-cron

• This should install the cronjob and the agent will begin reporting data.

• To enable the CloudWatch agent to send data from the instance, we must attach an IAM role to the instance. The role to attach is CloudWatchAgentServerRole.
