I'm currently using W3TC Version 0.9.2.11.
In the monitoring section of W3TC you can add your New Relic api key and set the app name. This gives you a nice dashboard of page load times, database time, etc.
We have a load balancer with two separate servers running the exact same setup of a wordpress site. I have New Relic installed on both and both servers have separate newrelic.appnames. Inside W3TC you have to link your New Relic dashboard to one app. I have two separate apps, to which one do I link it? Or should I make the appnames for both servers the same? But then I would get average data displayed in New Relic UI.
I need some advice from someone with more experience on this scenario.
