Power

This is where we should keep track of info about the power supplies, power usage, etc.

apcupsd

The daemon apcupsd looks useful for controlling the power supply.

Some snmpget commands

Here are some common OID's. SNMP uses these OID's to get very specific, discrete pieces of information from a device.

As an example, we've run the following commands to get info about the power supply for cluster:

> /usr/bin/snmpget -v 1 -c public ups.cluster.earlham.edu .1.3.6.1.4.1.318.1.1.1.1.1.1.0 
SNMPv2-SMI::enterprises.318.1.1.1.1.1.1.0 = STRING: "Smart-UPS RT 10000 XL" 
> /usr/bin/snmpget -v 1 -c public ups.cluster.earlham.edu .1.3.6.1.4.1.318.1.1.1.3.2.5.0 
SNMPv2-SMI::enterprises.318.1.1.1.3.2.5.0 = INTEGER: 9 
> /usr/bin/snmpget -v 1 -c public ups.cluster.earlham.edu .1.3.6.1.4.1.318.1.1.1.2.2.3.0 
SNMPv2-SMI::enterprises.318.1.1.1.2.2.3.0 = Timeticks: (132000) 0:22:00.00 
> /usr/bin/snmpget -v 1 -c public ups.cluster.earlham.edu .1.3.6.1.4.1.318.1.1.1.2.2.1.0 
SNMPv2-SMI::enterprises.318.1.1.1.2.2.1.0 = Gauge32: 100 
> /usr/bin/snmpget -v 1 -c public ups.cluster.earlham.edu .1.3.6.1.2.1.1.6.0 
SNMPv2-MIB::sysLocation.0 = STRING: Noyes Machine Room, Arctic Rack 
> /usr/bin/snmpget -v 1 -c public ups.cluster.earlham.edu .1.3.6.1.4.1.318.1.1.1.2.2.2.0 
SNMPv2-SMI::enterprises.318.1.1.1.2.2.2.0 = Gauge32: 26
