Complete noob to Nagios - decided setting it up on a Pi would be a useful way to learn. Initial googles lead me here & after a couple of evening's tinkering - I'm up and running! Monitoring a few internal devices / Pi's + a web server carrying a few sites on AWS

Took a while to get upto speed with the differences between the NEMS install compared to a standard install documented all over the internet - but after you learn the directory location differences, everything started to fall into place.
Great stuff dude - keep up the good work!
