I have an APC Back-UPS XS1500 powering my computer. It may be overkill for a single computer but it makes me feel secure.
Gnome power management will not install on CentOS 4.4 because of dependency problems.
I have installed the acpupsd daemon and this will protect me against power failure but the GUI interface to it, gapcmon, will not install due to dependency problems. I know that some will not consider a GUI interface important but I like to see what is happening if and when my A/C power gets disconnected and my computer is running on UPS battery power, and I like to be informed of this when I am online. Without gapcmon, or trying to hack my own program, this is not possible with CentOS 4.4, although as I said the apcupsd daemon will automatically and gracefully shut me down if my A/C power goes off and my UPS gets close to running out of backup battery power..
I realize that CentOS 4.4 is based on reliability, and not the latest and greatest software out there, but I am wondering what total UPS solution actually exists for it, or for RHEL4 which customers of the latter have used. I can live with apcupsd, and I realize that with an upcoming CentOS 5 there will probably be better compatibility, but I was wondering if there is any other total solution for the time being which anyone else has used. Thanks !

I do remember there was some kind of web interface for apcupsd. I even had it installed once on Centos 4 box. Basically, it'll just display status of UPS on the web page. While not the same thing as having a tray icon, at least you'll be able to easily check the status of your UPS.
Not sure if it was part of apcupsd, or something separate.

You are right, but this software needs to be manually run for the end user to find out what is happening.
What I really want of course is for a visual window to popup whenever there are A/C problems, and whenever the A/C has lost power and the UPS battery is getting low.

It is part of apcupsd. I will look at it and see if I can get it going in CentOS 4.4. Thanks for reminding me of it.

apcupsd should already do something similar at the console. You should get a warning in your terminal windows stating that you're on battery and blah blah. You can simply modify /etc/apcupsd/apccontrol so that instead of the 'wall' it sends out, it uses gdialog or zenity, which would give you the popup window you want.

Thanks for the tip about changing apccontrol appropriately.
IIRC APC has free Linux software for their upses as well.

That's a new one. Have you tried the most recent version?

Their free Linux software ridiculously needs a Windows server OS to run.

The latest Linux version is the free business edition. It specifically states in that version that a Windows server must be running in conjunction with Powerchute business edition for Linux in order to use the Powerchute for Linux version.
Hi Edward,
I don't now the answer to your questions, bit maybe the next info can improve the situation: http://www.mgeups.com/download/soft/explore/eng/ptp/ptp_sol.htm?os=LINUX
I've not tried it, but it sounds great (especially because this Red Hat certification: https://www.redhat.com/apps/isv_catalog/VendorProfile.html?vendor_id=1827)
I hope this info will be useful.

The UPS I use is an APC UPS. This is a completely different brand. I did get the apcupsd daemon to work with my UPS. I just have to create a nice notification system. Thanks nonetheless.

Is there a problem with nut? Other not being in EL4? It's packaged for Fedora, so a port shouldn't be difficult & may be done.

I have been using NUT, but somewhere between 2.0.0 and 2.0.3 something got broken -- my config files now result in the hiddev device files vanishing when NUT tries to start up. The only way to get them back is to reboot the computer, and as this is a server I found the best way was to get some .src.rpms from an older Fedora and run those.
This problem bit me when I ran FC3, and was repeated in RHEL and CentOS 4. Which is a pity, because I'd like to use the extended attributes of my APC UPSs which are allegedly available in the later versions of NUT.

I was put off by nut, as opposed to apcupsd, because of what seemed like very complicated instructions to setting it up for my UPS. I will take another look at it but another replier did say that there were problems with it under CentOS 4. Perhaps that was just his experience and I can set it up successfully for my system.
The apcupsd actually works quite well in shutting down my system successfully if the A/C power is down and the UPS is running out of battery time. It is just that the GUI interface, called gapcmon, requires newer libraries than CentOS 4.4 can handle. Probably with CentOS 5 those libraries will be OK. CentOS 5 should be out "real soon now", right ? <g>
