Description: The amount of memory cache fetches, in proportion to total cache fetches.
What is cacheMemoryUsageRatioPercent?
The percentage of all cache fetches that were served from the fast in-memory cache rather than the slower disk cache, which an admin watches as a key cache-efficiency indicator -- a falling ratio can mean the working set of hot URLs has outgrown the memory cache allocation.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9600.1.6.3.12 snmpwalk -v2c -c public <target> INFORMANT-ISASERVER::cacheMemoryUsageRatioPercent
Get a specific instance (index 1):
