Below is the list of SNMP OID that I used to create templates in Zabbix and other scripts.
On the test, I used Cisco Catalyst 6509-E with firmware 12.2.
OID and MIB can be checked from Linux, for example with the command:
snmpwalk -v 2c -c public 192.168.1.1 .1
Average CPU load in 5 seconds:
.1.3.6.1.4.1.9.2.1.56.0
Average CPU load in 1 minute:
.1.3.6.1.4.1.9.2.1.57.0
Average CPU load in 5 minutes:
.1.3.6.1.4.1.9.2.1.58.0
CPU Total Physical Index:
.1.3.6.1.4.1.9.9.109.1.1.1.1.2
CPU Usage 5sec/1min/5min Rev:
.1.3.6.1.4.1.9.9.109.1.1.1.1.6
.1.3.6.1.4.1.9.9.109.1.1.1.1.7
.1.3.6.1.4.1.9.9.109.1.1.1.1.8
Uptime:
.1.3.6.1.2.1.1.3.0
Reason for reboot:
.1.3.6.1.4.1.9.2.1.2.0
Temperature sensors (description and condition):
.1.3.6.1.4.1.9.9.13.1.3.1.2
.1.3.6.1.4.1.9.9.13.1.3.1.3
Coolers (description and condition):
.1.3.6.1.4.1.9.9.13.1.4.1.2
.1.3.6.1.4.1.9.9.13.1.4.1.3
Power supplies (description and status):
.1.3.6.1.4.1.9.9.13.1.5.1.2
.1.3.6.1.4.1.9.9.13.1.5.1.3
Power supply table:
.1.3.6.1.4.1.9.9.117.1.1.1
The total possible load in watts, the result is multiplied by 0.42, where 42 in my case means the number of volts of the unit, on other devices there can be for example 12 volt units, etc. (the result can be compared with the values in the console by typing the show power command):
.1.3.6.1.4.1.9.9.117.1.1.1.1.3.15
Used Watt with the specified number of volts, in my case, the result is multiplied by 0.42 (system power used):
.1.3.6.1.4.1.9.9.117.1.1.1.1.4.15

.1.3.6.1.2.1.47.1.1.1.1.2

Memory Pool Name/Used/Free:
.1.3.6.1.4.1.9.9.48.1.1.1.2
.1.3.6.1.4.1.9.9.48.1.1.1.5
