Memory Utilization for Modular IOS

Our monitoring software is reporting high memory utilization for a router with the new modular IOS, 89%. Is this normal?

Does this agree with the "show proc mem" and "show mem summ" outputs? If so, you might want to take this to the switching forum.

Re: Memory Utilization for Modular IOS

"sh proc mem" and sh mem" show show sys memory at 65.5MB total, 36.6MB used and 28.9MB free. That is more like 56% used. The management program, Solarwinds Orion, is reporting total mem is 64MB with 55MB used or 89%.

The 56% is still higher than the 30% we had with the previous version of the IOS. Does the modular IOS use more memory?

Any ideas on what the NM software maybe is seeing on the memory usage?

Re: Memory Utilization for Modular IOS

You'd have to take the memory usage question to a switching forum. As for the OIDs used by Orion, I'm guessing it is using objects from the CISCO-MEMORY-POOL-MIB to get the free and used RAM values. But this is just a guess. You would need to either ask SolarWinds, or get a sniffer trace to determine what objects are being used to see if there is a bug related to those objects on modular IOS.
