Sitting here in a heavy rainstorm listening to my 3 UPSs "click" ominously, so I decided to take a brief look at the output of pwrstat on my office PC;
On the server;
I thought it was pretty cool that it showed the event, but also that the two UPSs report different info in several ways. They are plugged into different circuits, reporting different voltage (I checked several times nearly simultaneously) and the last event differs. Curious.I have no idea if that's a hardware difference or actually line difference. Assuming that the two different outlets are on opposite mains might explain the voltage difference and establish why a UPS and/or power cleaner is a good idea for any sensitive electrical equipment like PCs or A/V equipment.
I do like that it shows Load in watts.
