[Nut-upsuser] battery not installed, but battery still 100% and NUT 2.7.2-4 does not catch this and report a error

[Jon Bendtsen]

Hi

debian jessie, nut 2.7.2-4

APC Smart-UPS 1500 connected through USB, running nut driver usbhid-ups


This UPS powers my switches, internet connection and my monitor server that 
monitors this and my other UPSes + runs smokeping and nagios.


But recently a powerloss seemed to have shutdown my monitor PC immediately, so 
it did not shut down the other servers cleanly. Power seem to be lost immediately.


But my APC Smart-UPS 1500 always reported everything OK.

output from CGI scripts

when I go into treemode though, I see something interesting

what? no battery installed, and the status is ALARM? how come NUT doesnt report 
this?

notice the value of parsing, first it is ALARM, and then OL. But if only the 
last value is returned, then everything seems okay and NUT never reports the issue?


for my other UPS'es it looks like this, only ever having OL as value.
