Support #14407
UPS received and connected
0%
Description
This morning we connected the UPS to the server, as once again last night there was a power cut...
Probably you will need to pass by and see if it needs to be configured in a way so that the turning off could be done properly by the UPS itself when the batteries drain out

Renamed nutdev1 to ups in the config files.

Now that nut seems to be OK, i looked up to see how to monitor - eg. with graphs etc. Found https://collectd.org/wiki/index.php/Plugin:NUT . But https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1009666 tells that the Debian stable (bullseye) version of collectd hos not support for nut, but it is back in bookworm.
Decided to upgrade the dom0 to bookworm (testing).
#5 Updated by Philippe May about 2 years ago
dom0 upgraded to bookworm, but there's no nut plugin in the collectd package.
Got a previous version and copied manually the nut.so file in /usr/lib/collectd/. Restarted collectd and data seems to be accumulating in /var/lib/collectd/rrd/dream.csr.av/nut-ups .
Tried to find a simple tool to graph rrd database on console, but could not find. Web based tools (eg. cacti) is clearly the most popular option. To be continued.
