> You could set up a monitoring system for the monitoring system... I'm considering this for a home automation system: a smaller, simpler device connected to the network, powered via battery (recharged from mains but surge protected) aka UPS, and able to send SMS messages via mobile network. The idea is it's a heartbeat/monitoring system for the essentials: - power cut/outage - network down/outage - main server down, or has some problem Then I can get an SMS telling me something's wrong.
