I was talking about pollfreq in usbhid-ups,

When I get time, I plan to test UPS notifications. I'm interested to see 
how NUT reacts.

I did notice one thing though after switching to NUT. The many APC RS 
UPS's I have spam battery disconnect/reconnect (no battery) messages as 
one of the indications that a replacement battery is needed.

NUT didn't care this was happening, as there were no messages or upsc 
output to indicate an issue. So UPS notifications are not working or NUT 
is ignoring short-lived events. The replace/bad battery light was going 
on and off randomly, so I knew it was happening at the time.

If I unplug the battery for real, NUT will eventually tell me.
