hwPerfCacheWriteUtilization
Module: ISM-PERFORMANCE-MIB
OID (symbolic): ISM-PERFORMANCE-MIB::hwPerfCacheWriteUtilization
OID (numeric): 1.3.6.1.4.1.34774.4.1.21.7.1.3
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: Description.
What is hwPerfCacheWriteUtilization?
This OID reports the percentage of a cache partition currently occupied by write cache, or dirty, data. An admin monitors this because a persistently high write utilization can indicate the array is struggling to destage writes to disk fast enough.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.34774.4.1.21.7.1.3 snmpwalk -v2c -c public <target> ISM-PERFORMANCE-MIB::hwPerfCacheWriteUtilization
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.34774.4.1.21.7.1.3.1 snmpget -v2c -c public <target> ISM-PERFORMANCE-MIB::hwPerfCacheWriteUtilization.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> hwPerfCacheWriteUtilization.1
