Most startup and shutdown messages (as well as runtime kernel messages) are logged in the file /var/log/messages

Power failure messages may only be successfully logged if you have some form of UPS, as they will be logged only after the power has failed.

In the /etc/inittab file, there are some lines line this (this is how they appear on SuSE):
Quote:
# what to do when power fails/returns
pf:owerwait:/etc/init.d/powerfail start
pn:owerfailnow:/etc/init.d/powerfail now
#pn:owerfail:/etc/init.d/powerfail now
po:owerokwait:/etc/init.d/powerfail stop
Looking at my /etc/init.d/powerfail script, I see these lines:
Quote:
POWERFAIL='THE POWER IS FAILED! SYSTEM GOING DOWN! PLEASE LOG OFF NOW!'
POWERFAILNOW='THE POWER IS FAILED! LOW BATTERY - EMERGENCY SYSTEM SHUTDOWN!'
POWERISBACK='THE POWER IS BACK'
So I'd imaging that these are the strings to look for. They may vary completely on Red Hat.

You could also check if /var is mounted as a synchronous filesystem (sync option in /etc/fstab). If it's not then the message, if logged at all, is unlikely to make it out of the write-cache for the disk.

Another suggestion: try passing the -i option to grep for case-insensitive matches.

Thanks rjlee, i m having this problem on suse 9.1. I m trying to find a way to know when my ups after light was gone went off bcz the day it happend was sunday so no body was there to poweroff the system and it went straight away as somebody would have pulled the plug out :-( .... so no logs generated i guess ??? or is it the way "whenever light goes off nd pc switched over to ups they get a log entry of this switch over"
i dont think so... i can be wrong plz correct me if so..
