Very cool! Looking forward to trying it out. My current solution had been a dead-simple crontab script that pushed some stats to a static html page every hour. It's ugly and a little dumb so I'd been looking for a better solution, and this looks perfect.
Hey, I have a project similar to groundcontrol but un Python, is called RaspCTL[1][2]. You add/execute commands thru a web interface, radio support (using mpd), can manage the daemons, dashboard with the memory usage/processes, processor temperature, etc...
And just right now I'm working on an alarm system, where you'll be able to launch any arbitrary commands or start/stop playing a radio. In a few days I'll release the new version.
BTW, for the ones who have a dynamic IP and want to use a Dynamic DNS service for being able to access to your RPi from the internet, you can check this out[3].
Thanks!
Librato also has a feature that lets you get alerts to your email if you set thresholds on metrics (disk space, temp, etc).
The free tier is OK for me too.
