Apc 1500 Ups

[beckx020]

I got this UPS from work (even computers are downsized!) that was about 6 months old for $25.00. I've been using it since spring running systems for folding@home. The UPS is one of those that all power draw is from the battery, not a standby.

1 - 17in monitor
1 - Linux server (amd 2000 + 120 gig drive)
3 - diskless Linux blades (amd 1700s boot from server)
1 - Win PC (amd 2500 + 120 gig drive)
1 - Win PC (Intel 1.4 + 80 gig drive, cd, dvd)
1 - gigafast switch

These have been running just fine until last week. My monitoring system was in alarm when I got home from work and everything connected to the UPS was off. My other UPSes didn't record anything, but I figured what the heck and powered everything on. UPS looked ok on battery and power draw. Yesterday, same thing happened. Then again last night. I'm never home when this happens, so don't know what is going on with the power. But when I rebooted everything the last time, the power draw was 2 dots higher than it normally is, and the light blinks that basically says the battery is draining faster than it's recharging. I left the server and 2 win systems on the UPS and it's keeping up, but can't have anything else on it now.

So, my question is, is the battery going out in the UPS or is one of my systems drawing way too much power? If it's one of the systems, is there an easy way to figure out which one it is? I tried booting them one at a time and I get only one light on power draw, so that doesn't help.

Since I got it used, even though it's not very old, I can't get it replaced from APC since I don't have the original receipt.

Seems like you should take a look in your abend log files in your server it would have entries for changes for recent events
on your server system. Look post again with the results.

What is an abend log file? Does it live in /var/log? If not, where would I find it?

I'm sorry to sound clueless, but unless I have a couple books and instructions in front of me, or it's something I setup myself, I am clueless in Linux.

I'd look at replacing the battery.
