I am currently using NewRelic for a Rails production project, around 5 EC2 servers, and the pricing for a non-free account is extremely bad (personal opinion) while of course the free account is no good since the data only sticks around for 1 day.
Does anyone have any experience with any alternatives to NewRelic that they used in a production environment successfully?
After doing research on the topic I found many alternatives and a strong contender, but I would like to get some opinions for someone that I know for sure (hopefully) used the service themselves.
Cheers.
