Issue: looking for a snmp OID to poll power supply status (Inbuilt Power Supply -  no redundant power supply in this scenario). Possibly what we see in show environment.
CSE analysis:
I tried using the OIDs belonging to CISCO-ENTITY-FRU-CONTROL-MIB , like cefcFRUPowerOperStatus and cefcFRUPowerAdminStatus but it didn’t return anything.
NOTE: I have done all the snmp walks from the Linux server. Do I doubt it’s something to do from the snmp manager side.
Couple of observations. The  CISCO-ENTITY-FRU-CONTROL-MIB talks about the field replaceable power supplies, so I doubt if it’s going to return the value for inbuilt power supply.
Second, I noticed that there are snmp traps supported for power supply and threshold setting. See configuration below. Is it that only traps works for power supply and environment related details?
Snmpwalk on cefcFRUPowerStatusEntry returns nothing:
[root@tonbenso-eagle bin]# ./snmpwalk -v2c -c public 172.16.169.29 1.3.6.1.4.1.9.9.117.1.1.2.1
SNMPv2-SMI::enterprises.9.9.117.1.1.2.1 = No Such Object available on this agent at this OID
Snmpwalk on cefcFRUPowerOperStatus returns nothing:
[root@tonbenso-eagle bin]# ./snmpwalk -v2c -c public 172.16.169.29 1.3.6.1.4.1.9.9.117.1.1.2.1.2
SNMPv2-SMI::enterprises.9.9.117.1.1.2.1.2 = No Such Instance currently exists at this OID
Snmpwalk on cefcFRUPowerAdminStatus returns nothing:
[root@tonbenso-eagle bin]# ./snmpwalk -v2c -c public 172.16.169.29 1.3.6.1.4.1.9.9.117.1.1.2.1.1
SNMPv2-SMI::enterprises.9.9.117.1.1.2.1.1 = No Such Instance currently exists at this OID
[root@tonbenso-eagle bin]#

I tried polling the ciscoEntityFRUControlMIB to see what all values it return. It just returned enterprises.9.9.117.1.3.1.0 = INTEGER: 2. Meaning cefcMIBEnableStatusNotification is FALSE (value 2). Meaning cefcModuleStatusChange, cefcPowerStatusChange, cefcFRUInserted, cefcFRURemoved, cefcUnrecognizedFRU and cefcFanTrayStatusChange are prevented from being sent.

Found couple of bugs:

Answer 1

Hi
I've got an ASA with redundant power supplies. An ASA5585. So I have the need to monitor them. :-) So how can we do it?
Also I've made a SNMP-Walk through the ASA v8.4(2)8 and it doesn't show up any ENV-MIB values. The
1.3.6.1.4.1.9.9.13 tree is not available. Are you shure it's available on the ASA?
Funny is also that the command "show snmp-server oidlist" from the 8.4 configuration guide is not available on the real CLI. I think the documentation guys were faster than the coders. ;-)
Kind regards
