How to get Cisco ASA firewall CPU monitoring?

What OID is used for ASA firewall to monitor CPU?

Cisco Adaptive Security Appliance Version 8.0(5)19

I understood CPU utilization is monitored from the  cpmCPUTotal5minRev OID 1.3.6.1.4.1.9.9.109.1.1.1.1.8. part of the CISCO-PROCESS-MIB.  In the absence of this OID we were using avgbusy5  OID (1.3.6.1.4.1.9.2.1.58). However, the avgbusy5 OID has been deprecated by cpmCPUTotal5minRev

and  cpmCPUTotal5min OIDs, therefore some SNMPAgents may not respond to a poll of this OID if queried.

avgbusy5 OID (1.3.6.1.4.1.9.2.1.58).

I found a few post in google referring to use the below OID'S

  Are these the OID's needed to be use for CPU?

cpmCPUTotal5sec

--- .1.3.6.1.4.1.9.9.109.1.1.1.1.3

cpmCPUTotal1min

--- .1.3.6.1.4.1.9.9.109.1.1.1.1.4

cpmCPUTotal5min

--- .1.3.6.1.4.1.9.9.109.1.1.1.1.5

But what if the oid .1.3.6.1.4.1.9.9.109.1.1.1.1.5 is not available in SNMP walk?  Is there a update SNMPAgent available from the vendor to include this mib or what is suggested for monitoring CPU for Cisco ASA firewall Version 8.0(5)19
