We have all APCs and they work fine in our DC. They work fine for us which include our windows and linux servers.

The link is more recent, because he mention XS 7.

I got acancel AARP (done, should have check by 4/13 and no mailings by 6 weeks from 3/16)I got about 50% of the way into this, and had to move on to other projects. But I really need to get back to it.

I'll add another note for future reference here.

For Fedora 39 Server, apcupsd has another package apcupsd-cgi that can be used with a web server to display UPS status. However, you have to move the files it installs by default because they're not in the /var/www/cgi-bin directory.

sudo dnf install -y apcupsd apcupsd-cgi httpd
sudo mv /var/www/apcupsd /var/www/cgi-bin/
sudo chown apache:apache /var/www/cgi-bin/apcupsd/*
sudo systemctl enable --now httpd

Should get it up and running.
I found 3 useful tools with it.

@whizzard said in Adventures in Graceful VM Shutdown:

How does the licensing work with multiple UPS?

The answer is...it depends. If you want OpMonis to monitor multiple UPS devices and shutdown things gracefully, it can do that using a single license but will only allow one shutdown list and would begin shutting down things as soon as your predefined threshold is hit for any one of the monitored UPS devices.

The other option is to get a second license of OpMonis to monitor the second UPS and have a dedicated shutdown list just for that UPS and its connected equipment.
