Installation is very fast an simple once you’ve created a free accound. Paid options are available and allow for more features.
You will need to record/save YOUR_LICENSE_KEY from your account for step 5 below.
sudo sh -c 'echo deb http://apt.newrelic.com/debian/ newrelic non-free > /etc/apt/sources.list.d/newrelic.list'
wget -O- https://download.newrelic.com/548C16BF.gpg | sudo apt-key add -
sudo apt-get update
sudo apt-get install newrelic-sysmond
sudo nrsysmond-config --set license_key=YOUR_LICENSE_KEY
sudo /etc/init.d/newrelic-sysmond start
You are done! Within a few minutes you should start seeing data on your consoles at the New Relic website.
