Many of my basic network services live on Raspberry Pi hosts. DNS, DHCP, my yum repository mirrors, my git server… These useful little machines make excellent utility hosts for simple tasks that don’t require much horsepower.

But if I have so many important things running on them, shouldn’t they be monitored?

It’s been a busy week. I lost many hours to the American Idol finale. Had to keep up on The Voice, of course. Then add in the massive (and very painful) project we’re in the middle of at the ever-dreaded job… The little time remaining was devoted to “final” tweaks to my internal network, and a major rework of my Amazon VPC in the hope of making my Amazon budget go a bit further.

It’s with the latter task that this story starts.
