Can anyone help me with the OID for getting the Power Supply Status of a Cisco ASA?
Did you try to monitor the following MIB table:
ciscoEnvMonSupplyStatusTable - 188.8.131.52.184.108.40.206.13.1.5.
Use the get table setting in your UnDP as you probably have more than one power supply.
Also interested in fans, and chassis minor/major if you have..
The CISCO-ENVMON-MIB:220.127.116.11.18.104.22.168.13 list the Voltage, Temp, Fan and Power Supply status.
Concerning the Chassis Serial Number, Orion Network Configuration Manager contains a report that lists all the Serial Number of the cards, chassis, etc. on your equipments.
If you do not have it you can poll the ENTITY-MIB:entPhyiscalTable / 22.214.171.124.126.96.36.199.1.1 .
EDIT: Check as well the CISCO-STACK-MIB:chassisSerialNumberString / 188.8.131.52.184.108.40.206.1.2.19 fount on this thread Re: Cisco Device Inventory
