[Nut-upsuser] trouble with ups mge evolution2200 and mandriva 2007 - nut 2.2 + PSP

[goudard sabine]

 Hello,
I'll be back with my MGE Evolution 2200 connected with RS232

I upgrade nut 2.0.1 in nut 2.2 + psp
as you ask me

PSP autodetect my UPS and autoconfigure NUT.

not really diffcult !

So I didn't change anything but I always have in my syslog these event
Nov 13 11:09:22 mezenc upsmon[3865]: Poll UPS [mgeups at localhost] failed -
Data stale
Nov 13 11:09:27 mezenc upsmon[3865]: Poll UPS [mgeups at localhost] failed -
Data stale

and my server shut down 

what can I do ?

Thanks for your help

Bonjour Sabine,

I'll add some more comments to Arjen's answer.

this is true.
You can find 2.2.0 packages, along with the MGE PSP here:
http://www.mgeups.com/download/soft/explore/eng/ptp/ptp_sol.htm
or
urpmi.addmedia mgeups http://opensource.mgeups.com/stable/mdvlinux/
with hdlist.cz

The PSP will autodetect your UPS and autoconfigure NUT.
So you might prefer it.

I've just made a statement about this: use mge-shut for the moment!

exactly. Moreover, this website is under heavy rewrite / update (part
of the MGE UPS dismantling, and the MGE Office Protection Systems
creation).

you should try to set pollinterval=10 in ups.conf

the default value (2 seconds) was fine with dumb / non verbose
protocols, but tends to overload unnecessarily the bus on both the
host and device side. Moreover, this kind of smart units supports
notification (the UPS sends info by itself, so less need to read
periodically)

I agree with Arjen's audit.
You should really give a try to the PSP, since it deals with all these
points.
Then get back to us if the problem still exists.
