What is hwPerfCacheHitRatio?
This OID reports the cache hit ratio for a cache partition, the percentage of I/O requests served from cache rather than disk. An admin uses this to judge overall cache effectiveness for that partition; a declining ratio can signal a workload change or a need for more cache.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.34774.4.1.21.7.1.5 snmpwalk -v2c -c public <target> ISM-PERFORMANCE-MIB::hwPerfCacheHitRatio
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.34774.4.1.21.7.1.5.1 snmpget -v2c -c public <target> ISM-PERFORMANCE-MIB::hwPerfCacheHitRatio.1
