What do all these New Relic metrics mean?

Just watched Joe Ferris video on optimizing performance for a Rails app. In that session he uses New Relic as a monitoring tool.

So I decided to implement New Relic for the latest app I’m currently working on:


New Relic is working fine, only I’m pretty new to this monitoring business and I’m not sure what all those metrics mean. For instance, I see for my PublicationsController#index action, I see a metric of:

avg response time: 1.26 sec

Is that a lot, or normal? Should I start optimizing that method?

So, I would love to find some documentation on all this metrics, and how to interpretate them.

Thanks for the advice,


Here’s a decent article on whether that response time is “good”. http://www.nngroup.com/articles/response-times-3-important-limits/
