	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.

			We can monitor two of our UPSs via SNMP [[Machine_List\|#UPS]]:
	Update: SNMP is annoying and complicated and has been removed almost everywhere. Mirror still runs it however.

			== Debian Setup ==
	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

			Install snmp and snmp-mibs-downloader (note: snmp-mibs-downloader is not available in stretch repository, so just download the deb from sid).
	[[Category:Software]]

			Download https://nagios.cscf.uwaterloo.ca/kiosk/powernet416.mib and place it in /usr/share/snmp/mibs

			== Getting Status ==

			snmpget -v 1 -c MSO mc-3015-h7-ups-1.cs.uwaterloo.ca PowerNet-MIB::upsBasicOutputStatus.0

			This will return something like:

			PowerNet-MIB::upsBasicOutputStatus.0 = INTEGER: onLine(2)

	== ~~Plugins~~ ==		== Windows ==

			There is a Windows distribution of Net-SNMP.
	It would be nice to have some plugins for Net-SNMP. Currently we query caffeine's apache statistics by enabled ExtendedStatus in apache, which is said to slow down performance. For postfix statistics, we depend on a customized mailgraph package. We should be able to implement both of these statistics directly in a Net-SNMP plugin. For both we would simply need to monitor the apache and postfix log files.
