Project Pi

Welcome to Project Pi, my little project to make use of my Raspberry Pi.

Project Goals

• To replace my CentOS VM used for monitoring my external IP and emailing if it changes
• To play with and increase my experience  more of Nagios Core by monitoring my home network
• To learn about distributed monitoring with Nagios and passive checks
• To automate the start up and shutdown of my home virtual infrastructure
• Give my grey matter something to think about
• Plus anything else I think of to add to the list !
