You can use SNMP to do this. It will set a flag in a certain OID which
you then need to monitor. I _believe_ you may even be able to tell
snmpd itself to call a process, but I don't recall on that.
Check the man pages.

You might look into something like daemontools[1]. It might be a
little overly complex. You could certainly script something yourself.
However, daemontools are quite reliable.
