I've been doing this for years and run into all sorts of ways of monitoring at many levels. Most of it was good and useful, some less so. I do not know a lot about it beyond "you should monitor" and "there are good tools out there to do it"
So I'm interested to see how everyone here does it (or not). Some starter questions:
- What tools are you using for it?
- Has the recent addition of JMX stuff in Jira been useful?
- Barring the obvious "it responds to standard requests", what do you look for in general?
- When you can quantify, what metrics do you use?
