I recently replaced my UPS and set up NUT (Network UPS Tools) for monitoring.
Everything works fine for a short time, but after a few hours, NUT reports “error: Data stale” in the web UI. After a few more hours, the web UI just stops responding completely.
I have NUT running on a Ubuntu VM in Proxmox. My UPS is a Tripp Lite (Eaton) SU1000RTXL2UA. It’s connected to my hypervisor via USB and passed through to the VM. Restarting the container fixes the problem. Any idea what could be causing this?
I’m browsing “all” and have no idea what this community is about.
Sorry you’re having trouble with your NUT
This is a community for individuals who are interested in running their own IT infrastructure at home. Personally, I have a server rack (like you might see in a datacenter) with a few servers installed in it. I use it for streaming video and audio to my TVs and portable devices, bulk storage, load-sharing two internet connections, monitoring security cameras, writing code, and a whole lot of other things.
“NUT” stands for “Network UPS Tools” and is a program that connects to an UPS (battery backup) and provides monitoring and remote shutdown based on power status. Unfortunately, as you say, I am having problems with my NUT at the moment.
