Hello,<br>
<br>
I've installed Nut (2.0.5) on RedHat a week ago, and upsmon seems to
generate false alarms every hour:<br>
<br>
...<br>
Jun 8 06:10:56 nutevalserver upsmon[2849]: UPS
usb-mge-evolution@localhost on line power<br>
Jun 8 06:35:46 nutevalserver upsmon[2849]: UPS
usb-mge-evolution@localhost on battery<br>
Jun 8 06:35:51 nutevalserver upsmon[2849]: UPS
usb-mge-evolution@localhost on line power<br>
Jun 8 07:24:47 nutevalserver upsmon[2849]: UPS
usb-mge-evolution@localhost on battery<br>
Jun 8 07:24:52 nutevalserver upsmon[2849]: UPS
usb-mge-evolution@localhost on line power<br>
Jun 8 08:27:07 nutevalserver upsmon[2849]: UPS
usb-mge-evolution@localhost on battery<br>
...<br>
<br>
I increased the values for MAXAGE (upsd.conf, from 15 to 30) and
DEADTIME (upsmon.conf, from 15 to 25), and that reduced the false
alerts to every some hours. That's strange, I thought a problem with
Maxage or Deadtime would result in 'Stale information' messages instead
of upsmon believing the UPS is on battery....<br>

usb-mge-evolution@localhost on battery<br>
Jun 13 04:22:59 nutevalserver upsmon[4020]: UPS
usb-mge-evolution@localhost on line power<br>
Jun 13 09:39:59 nutevalserver upsmon[4020]: UPS
usb-mge-evolution@localhost on battery<br>
<b>Jun 13 09:39:59 nutevalserver upsmon[4020]: UPS
usb-mge-evolution@localhost battery is low</b><br>
<br>
Here the situation got worse, upsmon thought the battery was low and
shut down the server. When I went to the server room almost
immediately, the UPS was fully charged, but the server had shut down.
It looks like either the driver (newhidups) or upsd is receiving wrong
information. I'm positive there are no electrical problems, as all the
other servers experience no problems...<br>
<br>
The UPS is a MGE Evolution 650 connected by usb to the server. The nut
driver I'm using is newhidups and the configuration looks like this:<br>
[usb-mge-evolution]<br>
driver = newhidups<br>
port = auto<br>
vendorid = 0463<br>
productid = ffff<br>
desc = "MGE evolution ups,in de installatieruimte ter test"<br>
<br>
Did anyone experience this before or has some advice? <br>
<br>
Thanks,<br>
<br>
