Nut upsuser - Nov 2013 - NUT-HAL (for use with USB UPS's and Gnome)

My first attempt to post this bounced -- this is a 2nd try.

-----------------------------------------------------------------

I've recently installed a CyberPower OR500 on a CentOS 6.4 system.

nut comes RPM'd as nut-hal -- and I've played a little with it - but
I'm trying to figure out
just what it provides at that point. (looking at the docs, I'm not quite
sure)

I'd like NUT on this system to allow my NUT master server to just monitor
and email notification as the system
NUT-HAL is running on is standalone on its UPS and that's fine with me.

I just want to know when the system has power issues and work NUT's
monitoring in with my Munin master server as well.

Should I move to the full NUT version on this system (and switch to Serial and
not USB?)

Thanks,

  -Ben

Sorry about that - Alioth, the server that hosts the lists, was down due to disk
failure:

The idea was that the HAL-based drivers would make the UPS appear like a battery
to the GNOME power management software, but then HAL was deprecated. So we never
really finished the documentation.

No need to switch to serial if USB is working - there should be a nut-usb
package or similar. You will probably have to remove nut-hal to install nut-usb.
The nut+upsd+upsmon solution is mutually exclusive with nut-hal, but they use
the same device-specific code, and it sounds like your device is compatible.

Oops! hahaha. I was wondering. ;)

I'll take a look and reply back.

Thanks Charles!

What yum shows me is: (this is on my NUT master server though just FYI)

The usbhid-ups drivers are included with nut.x86_64

So I guess my only question is:

Will nut's UPS driver happily coexist with the GNOME's UPS
"stuff"?
Or do I need to disable GNOME from sticking its fingers into NUT's control
of the UPS?

Thanks,
