Monitoring Rails applications

Hey everyone,

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.

Thank you!

So long Lennart Koopmann

Monit: Easy, proactive monitoring of processes, programs, files, directories, filesystems and hosts | Monit for all your system process monitoring needs Munin: http://munin.projects.linpro.no/ because people always love pretty graphs!

New Relic: http://www.newrelic.com/ Nothing gives you more detail about how your application is performing in the wild.

Those three will give you pretty much anything you could possibly want to know.
