As far as I know, the main is never lost, i never get any switch alerts, and never see any power surge/ flicker etc if that's what you're asking?
Yep. Or load surges, mains frequency change, UPS initiated self tests, etc.
In general, I doubt that nut is "making up" the event, and believe that the Cyberpower is actually issuing a LB signal which nut is dutifully logging. You can get definitive verification by running usbdump to capture all the traffic involving the ups, but I'm not sure it's worth it to delve this deeply though. :)
The ups model doesn't have a modifiable battery.charge.low, so I don't know of anything you can tweak with nut. You might search/ask in the nut users mailing list, but I expect that they will view it as a UPS problem. About the only other diagnostic recommendation I can think of is to change the load characteristics and see if it affects the issue. Temporarily removing the PoE switch perhaps.
Sorry I don't have a better recommendation.
Alright, appreciate the help. the UPS still has warranty, I just dunno exactly how to pick that battle with CP, they will say its WOD because self test passes. Fact of matter is, I've almost had this UPS for a year with flawless operation, and now this just started July 9th and coincidence or not with the upgrade. It would be a shame if I can't run 58% load on a UPS, i would think 80% would be where you don't exceed.
I called CyberPower support, and of course, they just brush it off as a NUT issue since the battery never drops charge so its not really low. He mentioned something about if your runtime goes below a certain value which can be specified if using "their power software" it would set an error. Is there something equivalent in NUT? Looking at the output again, i can change the battery.charge.low and .warning. I set charge.low = 40 and charge.warning = 50. battery.runtime.low is set at 600, so load would need to increase to the point where runtime drops below 600? It currently sits around 840.

Yes, you do want the warning to happen before the low. With your runtime number and low setting, you will actually initiate shutdown ~4 minutes after loosing mains.
I would tend to set all of them a little lower than what you have, but it depends upon your situation. I.E. how long it takes your systems to shut down. On my general purpose systems I use:
override.battery.charge.warning = 25
override.battery.charge.low = 20
override.battery.runtime.low = 300The reason I set these variables is because I have several servers that can take 2-3 minutes to perform a clean shutdown. Certainly longer than the 60 seconds or so warning I get from the LB signal.
For the firewall I use more aggressive values because pfSense shuts down quickly:
override.battery.charge.warning = 25
override.battery.charge.low = 10
override.battery.runtime.low = 180Truth be told, the LB signal on the UPS probably does a fine job here, and these settings are really not necessary. I just set them out of habit.
Your mileage may vary.

I plugged the UPS into a 2K12 server and installed CPs PowerPanel software, let it run for few days and didn't get any LOWBATT messages, then plugged it into my FreeNAS server which is using driver 2.7.3, internal driver .39. and no LOWBATT messages. Here is the output running on the FreeNAS box. So, something is not the same after the upgrade on pfsense because i dont see the LOWBATT message on 2 other boxes. Going to try mirroring the freenas NUT configs, (being doubtful that will matter) then going to have to find some time to reinstall pfsense to 2.3.2 and go from there).

When you put it back on the pfSense box did the LOWBATT messages immediately return?

Hi
I tried to "add" my UPS to my pfSense installation with the nut-package as well. Configured it with "Remote NUT server" and it shows me the load, the remaining runtime, sends me emails and so on. But it doesn't shutdown pfsense.
upsc on the remote nut server gives me:
battery.charge: 100.0 battery.charge.low: 20 battery.date: 2011-05-06 battery.runtime: 540.0 battery.runtime.low: 240 battery.voltage: 13.7 battery.voltage.nominal: 12.0 device.mfr: APC device.model: Back-UPS RS 550GI device.serial: 3B1119X20852 device.type: ups driver.name: apcupsd-ups driver.parameter.pollinterval: 2 driver.parameter.port: localhost driver.parameter.synchronous: no driver.version: 2.7.4 driver.version.internal: 0.04 input.sensitivity: H input.transfer.high: 276.0 input.transfer.low: 176.0 input.transfer.reason: Low line voltage input.voltage: 223.0 input.voltage.nominal: 230 ups.date: 2017-08-05 ups.firmware: 857.L3 .I USB FW:L3 ups.id: t-usv ups.load: 27.0 ups.mfr: APC ups.model: Back-UPS RS 550GI ups.realpower.nominal: 330.0 ups.serial: 3B1119X20852 ups.status: OL ups.test.result: NO ups.time: 22:12:53pfSense shows the same.
When the power fails (I plugged out the mains) I get this E-Mail:
Sat, 05 Aug 2017 03:05:33 +0200
UPS br550gi@t-usv.lan.xxxx.eu on battery
When the battery runtime goes below 4 mins (240 secs) like configured in the UPS I get this:
Sat, 05 Aug 2017 03:10:21 +0200
UPS br550gi@t-usv.lan.xxxx.eu battery is low
But nothing more happened. I waited about 2 more minutes, but pfSense didn't shut down and then I reconnected the mains.
What may I have done wrong?
-
I don't think you are doing anything wrong per se. By default, the nut slave (pfSense) isn't going to initiate a shutdown until the master server declares a low battery condition. This is different than a low battery warning.
When the master declares a low battery condition, it will send a notification to all the slaves indicating that there is a pending loss of power. The slaves will each disconnect from the master and then initiate their own shutdown. Once all the slaves have disconnected, the master will initiate its own shutdown.
If you want to override how the master determines when to declare a low battery condition, see the section on "ignorelb" in the ups.conf man page.
-
I have. The power kill logic is gone from the base os level. Still searching to find out when and why.
Ah, interesting. Sounds like it isn't an issue with my specific setup and it is a bug affecting anyone trying to use that functionality in the NUT package. Looking forward to seeing a fix for this whenever one can be found.
Hi, I wanted to see if there has been any progress on fixing this issue? Thanks.

Still working on it. Progress, but not ready for release yet. Should be this month.

After doing more research I found out, that not only my pfSense-Box wasn't shutting down. It was just the first one I tried. So there seemed to be a problem inside of nut, not inside of your plugin.
So I did more research, did deeper looks into the code and found a bug in the nut-driver. Posted the issue on GitHub: https://github.com/networkupstools/nut/issues/460 then I fixed it: https://github.com/networkupstools/nut/pull/461/commits/b82b9cf3b4695f3171b6250af431a6a3f7fc81c4 and did a pull request: https://github.com/networkupstools/nut/pull/461
It then has been reviewed and merged into nut https://github.com/networkupstools/nut/commit/bc6ca11be42281e6d7f36dc6cf2860c2fe950f66And now my problem is gone :) So: You were right, I wasn't doing anything wrong per se.
But thank you for your hint with "ignorelb" as this will help me with another problem when using apcupsd and nut at the same time :)

Just FYI, the PR for the dummy driver has gone in. The shutdown issue will have to be addressed in a follow-on release. This issue will need an enhancement in the core so it may have to wait until 2.4 is release.

Being a long time NUT user with pfSense this made me curious. Is this a new problem recently?
I've been adding stuff to rc.shutdown for "ages" to get proper shutdown-killpower-restart loops with a couple of APC serial ups-es:#Final shutdown stuff, UPS if /usr/local/sbin/upsmon -K; then # Warning message echo "POWERDOWNFLAG detected - Power cycling the UPS loads..." # Do shutdown /usr/local/sbin/upsdrvctl shutdown #Might be needed for power races # /bin/sleep 180 # /sbin/reboot fi -
The problem pre dates the current generation of the NUT package, but I'm not sure how far back it goes.
What needs to be done is pretty much the same thing you are doing with your patch to rc.shutdown, except that I need to genericize it so that it can be used with other packages such as apcupsd.
-
OK, thanks for the update
And nice to know that I didn't misunderstand anything with my fix, although it would be nice not having to remember the manual rc.shutdown patch every time pfSense is updated.Thanks, keep up the good work!

I upgraded NUT on pfSense to latest 2.7.4_5, and ever since I did that, it seems there is a high uptick in UPS communication errors. It's possible that it's another environmental condition that is going on here, but wanted to see if anyone else has had issues. PfSense is running on a small physical box, and it is directly connected via USB to a CyberPower EC650.
I've been getting flooded with emails as a result of this (yes, I know that I can turn them off). But it points to something else that is going on. Here is a dump of the ups related events for a small window on 9/4. In the last 24 hours, I have 232 events that are the Permission denied error.
One thing I did notice, if you look in /usr/local/etc/nut, all the *.conf files have perms of 640, but all the *.conf.sample files have perms of 644. Not sure if that matters or not, and also not sure if that's "new" or not.
