You can try this one 1.3.6.1.4.1.9.2.1.8.0 and compare with your values. I
used a time ago so I am not sure, but I think it is the free memory.
Hope helps

Assunto: RE: Monitoring Memory Utilization(%) on a router. [7:62800]
This reply from my colleague makes it very clear.
1) i do a "show memory" on a cisco 26xx router. It shows me the Total
> Processor Memory and Total IO memory.
> When i add up these 2 values, why is it not equal to total amount of DRAM
in
> your router (as shown by sh ver)???
Simply because Processor + I/O mem is not equal total DRAM.
The IOS loaded in RAM and additional datas need also some space:
muuma#sh ver | i with
cisco 2611 (MPC860) processor (revision 0x202) with 28672K/4096K bytes of
memory.
muuma#sh mem
Head Total(b) Used(b) Free(b) Lowest(b) Largest(b)
Processor 80B7D5D0 17312304 2375180 14937124 14745720 14822080
I/O 1C00000 4194304 1709592 2484712 2484712 2484668
Below you can see that the total main memory + I/O fits the physical 32
megs:
muuma#sh region
Region Manager:
Start End Size(b) Class Media Name
0x01C00000 0x01FFFFFF 4194304 Iomem R/W iomem
0x60000000 0x60FFFFFF 16777216 Flash R/O flash
0x80000000 0x81BFFFFF 29360128 Local R/W main
0x80008088 0x807C18AB 8099876 IText R/O main:text
0x807C18AC 0x80A78F27 2848380 IData R/W main:data
0x80A78F28 0x80B7D5CF 1066664 IBss R/W main:bss
0x80B7D5D0 0x81BFFFFF 17312304 Local R/W main:heap
That brings me to my second question::-))
Q:How do i get the total amount of DRAM installed in the router via SNMP??
Which MIB and OID?
Thanks
Simon

Could you send us the result of the `show memory` and `show version`.
Maybe it helps the discussion.

Hi,
1) i do a "show memory" on a cisco 26xx router. It shows me the Total
Processor Memory and Total IO memory.
When i add up these 2 values, why is it not equal to total amount of DRAM
in
your router (as shown by sh ver)???
2)Assuming the "sh memory" output does not give us the correct picture
about
memory utilization, which MIBs and objects should we monitor to get the
memory utilization( as a %)of the router?
Or can we atleast get the "free memory" , "used memory" or "total memory"
via SNMP and using MIB expressions, we can compute the Memory utilization
as
a %??What are the MIBs and objects to get this info?
Cheers
Simon
