The Computer Science Club runs Net-SNMP on all of our host machines. This provides real-time data on network, cpu and disk load, as well as memory usage. We also record temperature and fan speed data for capable hosts. On caffeine, we record apache and postfix statistics.

Update: SNMP is annoying and complicated and has been removed almost everywhere. Mirror still runs it however.

Installation of snmpd on our machines is done via puppet.

If you want to enable sensors:

  • sudo apt-get install lm-sensors
  • sudo sensors-detect
  • sudo modprobe the recommended modules and them to /etc/modules as needed; run sensors to verify that correct modules are loaded and working
  • sudo invoke-rc.d snmpd restart
