FreeNAS CollectD UPS metrics collector

Quick and dirty script to get UPS stats into CollectD so you can forward them to Grafana. Tested with a Salicru UPS configured with the blazer_usb driver.

Update 2020-07-26:

At some point between the original publication of this howto and FreeNAS 13.1, default nut metrics appeeared on my InfluxDB server, so even though nut sends fewer metrics than the script on this Gist (see the default-nut-metrics.png file as opposed to the file listing at the end of the howto), I'm going to stick with the default metrics, so I don't have to mess around with installing scripts every time my FreeNAS box reboots.

Configuration of python-broadlink in Python 3

I found many tutorials to install and configure python-broadlink, but all of them are for python 2, and the script has been ported to python3, so I decided to write this little howto.

Tested on a freshly installed Debian Buster container.

Run all commands with root privileges:

apt update

This little guide tries to solve the problems you can find to boot Proxmox 5.4.x freshly installed into newer AMD Athlon / Ryzen CPU computers/servers.

I tested this with a AMD Athlon 200GE.

0.- Install Proxmox PVE as you usually do 1.- Upon first reboot, edit the grub parameters of the default entry "Proxmox Virtual Environment GNU/Linux" with the "e" key. 2.- Locate a line that starts with something similar to (hints: starts with linux and says something about vmlinuz): linux /ROOT/pve-1@/boot/vmlinuz-4.15.18-12-pve root=ZFS=rpool/ROOT/pve-1 ro root=ZFS=rpool/ROOT/pve-1 boot=zfs quiet 3.- Add a new keyword " nomodeset" at the end of that line. 4.- Push F10 to boot the system. 5.- Edit /etc/modprobe.d/pve-blacklist.conf file, and add at the end the following line:
