Monitoring Memory Utilization(%) on a router.

[simonkc666]

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 be 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

For 2) http://www.cisco.com/warp/public/477/SNMP/contiguous_memory.html can be looked at.

Hi,

i read the doc u sent me. It was very informative. But what i am interested in is this:

Which MIB or OID should i see to get the total amount of DRAM installed in the router?

Cheers
