hardware-events
This software helps with the monitoring of a server motherboard.
The project started when I changed the FANs on a Supermicro motherboard and they started to run at full speed because their nominal speed was measured too low for the motherboard. I could have bought some other FANs, but I didn't want to.
This project:
- reads temperature from various sensors (CPU, motherboard, disks)
- sets FAN speed via the command line like
ipmitool(multi-zones) - sends sensor and FAN data to a monitoring platform (zabbix)
- suspends hard drive when there's no activity (while still being able to read the temperature before suspending)
I have it running on various Supermicro server boards (X9/X10/X11) and manage the different FAN zones separately.
Configuration
Everything is in the configuration file. This configuration is Linux based. The project probably works on FreeBSD (although not tested) but you might need to change the sensor settings (I'm using linux sysfs):

- This is where I found out I could control the FAN myself: https://forums.servethehome.com/index.php?resources/supermicro-x9-x10-x11-fan-speed-control.20/
