Chapter 12. Interface and Disk Cache Tutorial

The Interface and Disk Cache (that is available next to your device names under the Groups menu) are quick tools for setting up interfaces and disk graphs on your devices.

These caches provide useful mechanisms for indexing disks and interfaces. For example, commonly you want to graph your interfaces by their ifName (interface name) which is commonly something like 'Se2/1'. Doing a lookup each time you gather data would be very time-consuming, so the cache allows you monitor an interface by using it's name, and NetMRG will do the mapping to the correct ifIndex. NetMRG will do the same thing for disks
