[Nut-upsuser] MGE pulsar evolution 3000 discharges without nut noticing

I'm running nut 2.0.1 with an MGE pulsar evolution 3000 with the
mge-utalk (serial) driver on NetBSD 3.1 .

I had a very strange occurance in my basement datacenter this early AM.

the following was logged by upslog:

20080219 023452 100.0 123.0 049.0 [OL CHRG] NA 60.00
20080219 023522 100.0 122.8 049.0 [OL CHRG] NA 60.00
20080219 023552 098.0 123.0 049.0 [OL DISCHRG] NA 60.00
20080219 023622 097.0 123.0 049.0 [OL DISCHRG] NA 60.00

...

20080219 063429 019.0 122.6 049.0 [OL DISCHRG] NA 60.00
20080219 063459 019.0 122.8 049.0 [OL DISCHRG] NA 60.00
20080219 183013 100.0 121.1 050.0 [OL CHRG] NA 60.00
20080219 183043 100.0 120.9 049.0 [OL CHRG] NA 60.00

the good news is the UPS held up for four hours.

the bad news is that nut completely ignored that the UPS was
discharging, and none of my connected machines shut down properly.  I
know that the UPS driver was running, because if was not, upsd would
have complained loudly and frequently.  I know upsd was running (on the
connected server as well as all the clients), because if it was not,
upsmon would have complained loudly and frequently.

there were no indications in my logs that nut was paying any attention
to the situation.

why did my UPS decide to discharge its battery when there appears to be
no power outage? (just looking for suggestions and guesses here from
other MGE users...)

why did nut not see that my UPS was discharging and the battery
percentage running down and take appropriate action?  "OL DISCHRG"
status in the logs seems nonsensical.  I have only seen this condition a
few times before in my logs:

	20061002 002628 094.0 079.6 045.0 [OB DISCHRG] NA 60.00

nut saw this one, and shut everything down, as expected.

Nothing wrong here. It was probably running a battery test, since the
input power seems to have been present at all times (it is reporting OL).

It didn't ignore it, the UPS just wasn't critical at any time during
this
test. By default, NUT will only start a shutdown sequence when the UPS
becomes critical (ie, no input power available and batteries low). From
the above, I conclude that at no time the input power was lost and neither
the batteries were low. You have a couple of things to configure to make
NUT behave otherwise.

I don't see any problems here.

Yes, it was. It was reporting [OL DISCHRG] all the time. There was just
nothing NUT needed to do.

Most probably, because of an (automated) battery test. Or someone
initiated one, but given your surprised reaction, I guess it wasn't you.

This is all documented (in the FAQ for instance). This makes perfect sense.

Sure, here you see that the input power is actually lost (the line state
flipping back and forth between OL and OB).

And here the batteries where probably already low and NUT decided the UPS
was critical and it was time to shutdown.

There you go. This seems to be an awful short interval (three hours).
Again, read up on the FAQ and come back if you anything is not clear to
you.

as always, Arjen already replied.
I would just add that you should prefer the mge-shut driver.
It's more complete and maintained that the mge-utalk (which is for the
legacy ASCII protocol).
