I have a question to all those who use Rails in a professional way and have to monitor their applications: What values do you monitor? And how?
I don’t mean the health values of the machines or the network. I mean just the Rails applications. I would think of number of logged in users, memory/CPU usage of Mongrel threads, page requests, concurrent sessions, number of queries, avg. response times of queries and cache stuff.
