How can I delay pfsense powering down until esxi has completed shutting down?

The HOSTSYNC variable controls how long the master will wait for slaves to initiate their shutdown. You can find information on this in the ups.conf man page.

Thank you - I'll give it a try.

I've noticed the following errors appearing in my logs, any idea why this would be?

I believe it means that the variable is marked read-only in the SNMP MIB. For more information on this, I would suggest checking the nut users list.

FWIW, if it were me I would just remove the setting of runtime and use charge %. You don’t need both.

pfsense 2.4.2-RELEASE-p1 (amd64)
nut 2.7.4_5

Polling an APC AP9631 on the LAN via SNMP.

When I reboot the appliance, UPS status shows as down. Log has a bunch of these:

Feb 19 21:40:27 upsmon 66529 Poll UPS [office-UPS] failed - Driver not connected
Feb 19 21:42:22 upsmon 67668 Startup successful
Feb 19 21:42:23 upsd 68233 listening on ::1 port 3493

Feb 19 21:42:23 upsd 68498 Startup successful
Feb 19 21:42:24 snmp-ups 68710 Startup successful

Now when I go to restart the service via the GUI In Services -> UPS, it starts up perfectly right away.

apcupsd was installed but I removed it when switching to NUT.

I tried using snmp v1 instead of v3 thinking I screwed up my v3 credentials but that doesn't seem to be the issue. Even with snmpv1 it wont come up after a reboot until I manually intervene.

I tried some of the retry and delay parameters in the additional parameters for ups.conf but they also didn't help with this


maxretry=3
retrydelay=10
pollinterval=5
snmp_retries=10
snmp_timeout=2
pollfreq=10

dennypage

Please give the following a try:

Get rid of pollfreq and pollinterval.

Set these variables in the Extra Arguments to driver section:


snmp_timeout=2
snmp_retries=10

Set these variables in the Advanced section for ups.conf:


retrydelay=30
maxretry=20

Now reboot the box. When the box comes up, go to the UPS status page. [Do not attempt to start the service manually] If the UPS shows as needing attention, wait for the page to refresh automatically. If it doesn't auto refresh, after a couple minutes refresh the page manually. Does the UPS show as running? Or is it still down?

These settings work perfectly!

I am now back on SNMPv3 and NUT is performing as expected, across reboots and all. Thank you!

dennypage

That's good news. Now that it's working, you can probably tune the variables down quite a bit. In particular, the settings in Extra Arguments can likely be returned to their default values of 1 & 5. Or simply deleted.

I think actually found a bug (with the AP9631, fw 6.5.0).

I just deployed a second AP9631 out of the box. Factory reset, flashed 6.5.0, factory reset again, set up SNMPv3 and had the same issues I described before where NUT cannot communicate.

I have now noticed that if I have SNMPv1 DISABLED, NUT will fail to connect via SNMPv3 no matter what extra settings I provide. Simply turning on SNMPv1 in the AP9631 (fw 6.5.0) immediately lets them communicate. Very strange. Further testing is needed.

I have replicated this on the previous installation where I can break the SNMPv3 communication between NUT and the AP9631 by disabling SNMPv1, don't even need to reboot.

It sounds like SNMPv3 may not be properly configured/functioning in NUT. Can you post the contents of /usr/local/etc/nut/ups.conf please?

@dennypage:

I am going to find an SNMPv3 client and try replicate this in a moment. If a different v3 client fails in the same way the issue is with AP9631.

If it doesn't then there may indeed be a NUT issue. Maybe it has some routine to check SNMPv1 availability before anything else, even if only SNMPv3 is needed.

I realize the credentials are in there but it's a sandbox setup so this is not really a concern. My full, unedited /usr/local/etc/nut/ups.conf:

retrydelay=30
maxretry=20
snmp_version=v3
privProtocol=AES
authProtocol=SHA
secName=pfSense
authPassword=VtwHzSj6XQlmp9OFFa28NJcUL93qq5zZ4
privPassword=TpWsICXWm4CeKtwUehtvcBpDnBW0KZCC

[S10-AP9631]
driver=snmp-ups
port=172.16.10.5
snmp_timeout=2
snmp_retries=10

dennypage

SNMP parameters are part of the UPS specification. As such, they go in the "Extra Arguments to driver" rather than in the "Additional configuration lines for ups.conf" section. The advanced section is only for Global Directives (see ups.conf), and anything that is not recognized as a global directive is ignored by NUT. I know it's confusing, but it's how NUT's configuration works. Anything that comes from the driver man page (snmp-ups in your case) goes into Extra Arguments to driver.

Edit: So it seems it was using SNMPv1 all along due to my mis-configuration resulting in the SNMPv3 stuff being ignored. There is no bug. Now that I have the correct structure in ups.conf it is indeed trying to connect SNMPv3 but it is not authenticating. The AP9631's built in baby IDS keeps sending me notifications now that there are failed SNMPv3 authentications from the pfSense IP.

I will switch her back to SNMPv1 for now and troubleshoot my SNMPv3 setup with qtmib

dennypage

That makes sense. For what it's worth, most people use a read-only SNMPv1 group for UPS monitoring. There isn't any sensitive information in the stream.

The docu said a write community is needed to facilitate shutdowns. I wanted the UPS and NUT to coordinate that NUT will shut down pfSense when there's not much runtime left and then tell the UPS to shut off the outlet in x minutes and come back up when AC power is restored and battery has at least y % charge.

Otherwise pfSense will just shut down and stay down until someone presses the power button or the BIOS power on time is reached.

Ah, yes. Needing write permission to kill power makes sense. Note that the pfSense NUT package version 2.7.4_5 does not support issuing the final power kill order. This will come with NUT package 2.7.4_6 which requires pfSense 2.4.3.

xx_robot_xx

Hello,

How do you configure power-kill after shutdown? I have pfsense 2.4.3 and latest version of nut..

dennypage

Power kill is enabled automatically with pfSense 2.4.3 and 2.7.4_6 of the NUT package. No configuration necessary.

Hello,

I have a TrippLite Smart 1300VA unit connected via USB. dmesg does show it connected. This model is also one listed in NUT to use the USB driver (not the legacy TrippLite driver). I got readings from it very briefly last night when setting it up, but also a bunch of messages in the log about the data being stale. This was on pfSense 2.4.1.

Now it doesn't work at all. I upgraded to the latest NUT package. No dice. I upgraded pfSense to 2.4.3… no dice.

All I get is this in the status logs:
Apr 4 14:57:20 upsd 97125 User monuser@::1 logged into UPS [main]

Please run "usbconfig dump_device_desc" and post the output. Also, can you post the contents of /usr/local/etc/nut/ups.conf please? And lastly, the exact model number of the UPS.

Btw, where did you see the note about using the usbhid-ups vs. the tripplite_usb driver? I didn't find a Tripp Lite 1300VA model in the NUT HCL…

Ok the model number is SMART1300LCDT. I was at work when I posted and I forgot the exact model number. I was told I can use usbhid-ups from here: http://networkupstools.org/ddl/Tripp_Lite/SMART1300LCDT.html
