@g2_ufo Yes a dashboard widget for UPS stats would be great and is also included in the Future enhancements section of the Rockstor’s NUT implimentation as well, thanks for up voting. This is a personal favourite enhancement of mine but I think there are more pressing Rockstor issues that have to be addressed first so it may take a while to get around to this. I at least am not yet aware of how to go about this but hopefully we can get this neat feature in at some point. I would like to see % load myself but not every UPS has this as an output so that’s another wrinkle. We could poll the UPS (via the NUT Python wrapper) for its available info and then present as config options in the dashboard widget what options we know how to pot.
As to your email notifications point I totally agree; and I am hoping you are in luck. If you got to System - Email alerts and configure according to the docs section Email Notifications then you should receive all known NUT status changes. That’s the hope anyway. 
If you could let the forum know how you get on with this then that would be great. Thanks.
