Since upgrading to 2.7 nut keeps telling me "UPS is unavailable" and connection lost/unable to communicate. It's a cyberpower 1500pfclcd. It worked absolutely perfectly on 2.6. Not sure what might have changed? Using snmp to connect to the power panel software on a windows machine that hosts the UPS.
I've tried everything I can think of, removing, reinstalling, redoing config etc. It still pulls the stats so I know it's not actually a connection issue, the snmp portion and driver appear to be working properly.
I tried changing pollinterval to 12 and 15 and it still happened.
Edit: I am also noticing the "summary status" is blank. I think it used to say "online" and might explain what's going on
-
I can confirm through ssh that ups.status is blank which is why the nut package thinks it can't communicate.
On another server of mine (a Linux machine) ups.status shows the proper "OL" code.
So it seems something is broken with nut itself in this current release.

Not much to go on here... Start with posting your config and status pages?

@dennypage my follow-up reply gave the cause.
uspc confirms that ups.status is blank after updating, and so pfSense does not know whether it's online or not. All other snmp data displays fine.

@incith Please post your (complete) config and status pages. I will look at them tomorrow. If you want, you can post the complete output of upsc on your pfSense system as well.

@incith
I have the same thing happen lately. (23.05.1)
It works fine for a while but then says unavailable. I restart service and all works again. Sometimes for weeks, sometimes it quits the next day.
Also use a cyberpower 1500
Hardware is a Dell R210-II -
@DurUser My UPS.status is always blank. So it does not work even for a little bit for me. It thinks the ups is offline 100%.

@DurUser I think FreeBSD/pfSense/NUT has a somewhat general issue with USB based UPS’s.
IT’s well known Cyberpower UPS’es suffer very badly from this, but also several other units - fairly vendor agnostic - shows the same disconnect issues. I have two Eaton S5 UPS’s that suffer the same problem (and I have thoroughly tested its not the USB cable).
Common for all of them is that if you connect the same UPS to a Linux or Windows host they suffer no disconnect issues - so it’s likely something to do with either the USB UPS driver or the whole USB subsystem in pfSense.Up until 23.01 it was not a catastrophe because NUT would just reconnect to the UPS. But after 23.01 it no longer does that and a disconnect now means loss of UPS status/communication. I think work is being done on getting a never USB driver for NUT that attempts to reconnect again, but it will take a while - it will likely not cure the temporary disconnect issue though. That seems to be a deeper rooted issue.
-
@keyser agree with you observation. I have same problem with TrippLite disconnecting using usb driver. @dennypage (intel) and @Maltz (arm) have posted drivers to temporarily help with disconnects. @incith is using snmp driver and seems to never connect, which sounds like a different problem altogether.
-
@ghound yeah I literally had 0 problems at all on 2.6 pfSense using snmp. It always reported 100% correctly.
-
@keyser Sure, but it was working great before. Never had an issue until recent updates to pfsense. So something got screwed up that wasn't screwed up before. And yes, I did see those disconnects/reconnects happen before the update. That worked for me. Now it no longer reconnects I guess.
-
@incith Did you not have disconnects/reconnects ? Or never noticed it ?
-
@DurUser I did not have any disconnects. SNMP worked flawlessly.
-
@incith Wait, so you didn't have the ups directly connected to your pfsense box?
I am not sure I understand your snmp setup. -
Found the fix? Not sure why this hasn't been merged into pfSense 2.7. this is old it seems. pfSense using mib v0.51 and this is 0.52 to fix the issue

@DurUser correct....that's kind of the point of SNMP lol. CyberPower PowerPanel software does SNMP server. A windows server is the primary host for the snmp data. pfSense is a slave.
It'd be nice to see pfSense have an option for choosing master or slave in the snmp driver.

You likely had disconnects. You would not have noticed, because it immediately reconnected. When this happens, there is no notification.
-
@dennypage ...ok?
-
@incith Your prior post referred to an adjustment in polling interval. FWIW, I do not see any polling interval in the configuration you posted.
As to your actual problem, it is discussed here. Assuming that you are on an Intel or AMD based platform, you use the updated snmp-ups driver posted in that thread.
