> No, they're actually not. They're trivial to get to a state of "the process is running on my machine", but to actually get a set of suitable metrics presented the way you want them, that takes a while, especially if you're not already a skilled sysadmin. It's certainly more than "a couple of hours of sysadmin time every couple of years" that others in this thread suggest.

I said what I said not as speculation but out of experience. It's really not hard. Telegraf includes many of the metrics you'd want built in and others can be sent with minimal effort from most applications with StatsD.
