Sup720 FIB TCAM Usage Monitor

I searched around and saw examples of using expression mib and eem. But is there not a simple mib to poll for the equivalent of ? :

 FIB TCAM usage:                     Total        Used       %Used
 72 bits (IPv4, MPLS, EoM)     786432      516031         66%

that comes from the command:

#sh platform hardware capacity forwarding

I'm interested in collecting the "total", "used" and "%used" values over time.

I'd rather not add a script and I'm concerned about using expression mib to count half a million entries (should I be?).

I also looked at the CISCO-SWITCH-ENGINE-MIB and pulled:

Is there any relationship that can be gleaned from there to what I'm looking for?

Can anyone verify that the

Can anyone verify that the mib:

CISCO-SWITCH-HARDWARE-CAPACITY-MIB

specifically,

CshcFibTcamUsageEntry ::= SEQUENCE {
        cshc72bitsFibTcamUsed   Unsigned32,
        cshc72bitsFibTcamTotal  Unsigned32,

will provide the values equivalent to:

#sh platform hardware capacity forwarding

 FIB TCAM usage:                     Total        Used       %Used
 72 bits (IPv4, MPLS, EoM)     786432      516031         66%

??

It looks like this became available with 12.2(33) for C6500 sup720, and release 15 for 7600 - is that correct?
