Thanks for the kind words mex -- also thank you for the nagios plugin info -- adding that to my monitoring toolbelt.

Some more specific questions for you and others re: the guide I wrote:

- Are there any "essential" metrics I'm missing? I listed the 14 that I think are the most critical.
- Are there any Nginx features related to monitoring that I haven't covered (and should cover)?
- I want to make sure I also have good coverage for monitoring potential "breaking" issues with Nginx -- things that can overflow / top out. I've got open file handles as one of them, and the standard server-related stuff (cpu, memory, disk, bandwidth). Anything Nginx-specific I'm missing that are critical and could cause the application to sputter?

Many continued thanks.
