Just a lucky guess :-) We tend not to know about changes like this until 
someone reports an issue.

Thanks, good to know. PR6000LCDRTXL5U would probably also work.

Those are likely from the previous instances of upsd and upsmon - they look 
like the "errors" you get from sending SIGTERM to them.

The UPS drivers send their "connected" message to stdout, and they are not 
consistent about that, either. Pretty sure we have that logged as a bug.

Do you know the lowest syslog level FreeNAS logs by default? (debug, info, 
notice, etc. - see 
https://www.freebsd.org/cgi/man.cgi?query=syslog&sektion=3&apropos=0 for the 
list, and it might be in /etc/syslog.conf)

Again, the upsd and upsmon messages are secondary results from the driver not 
starting. Are there any log messages that reference usbhid-ups (the process 
name for your driver)?

^ Are these correct? (seems reasonable for a 4 x 12V battery)

Thanks, I'll add that to the HCL/DDL later.

At first glance, those numbers look reasonable. You can verify the load and 
voltage readings against your local configuration, but those aren't used for 
shutdown anyway.

The important thing is that the "ups.status" value includes "OB LB" (on 
battery, low battery) early enough for FreeNAS to shut down cleanly. We usually 
recommend testing this sort of thing with a dummy load, in case the signal 
happens too late, or the other portion (FreeNAS telling the UPS to cut power) 
does not work.
