RE: [opensuse] unexpected server reboot

If it is a question of power interruptions, that is what uninterruptable power supplies are for. Stores that carry IT equipment, like Staples and Future shop have units that are decent quality and modest price (there are keyboards that are more expensive). They provide both surge suppression and 'almost' uninterruptable power. But that I mean the power won't be suddenly cut off to your computer. Rather, depending on the capacity of the UPS, your machine can keep running for half an hour to several hours on the battery in the UPS. They can usually talk to your computer, again normally through a USB port, so when the UPS can no longer keep your machine going, it tells the computer to either shut itself off or hibernate or go into standby mode. I have my workstation plugged into a smaller unit, and it hibernates whenever the power is out for more than 5 minutes. I have several servers plugged into a much more capable UPS, which will keep them going for an hour (so I can shut them down manually, if the power is going to be out for any length of time. I don't know Linux well enough, but I would suppose that if you can catch system messages, you could log these, or if you can program the USB port (to listen on anything sent over the USB connection to the UPS, you can log that. Just a thought.... Cheers Ted

the reboot may as well be done by someby switching off the main AC (I do not own the whole house - there is even a switch out side on a road box :-()

aby idea of how I could monitor this better?

put a script to write a log entry into /etc/init.d/halt.local
