krCPUTotIOWaitTime
Module: KERNEL-READER-SUNMANAGEMENTCENTER-MIB
OID (symbolic): KERNEL-READER-SUNMANAGEMENTCENTER-MIB::krCPUTotIOWaitTime
OID (numeric): 1.3.6.1.4.1.42.2.12.2.2.12.5.1.1.1.7
Node type: OBJECT-TYPE
Type: DisplayString
Access: read-only
Description: Total CPU IO wait time in percentage of CPU delta. If V1 is the previous value of CPU IO wait time and V2 is the current value of CPU IO wait time then krCPUTotIOWaitTime = ( V2 - V1 ) * 100 / krCPUDelta .
What is krCPUTotIOWaitTime?
Percentage of this CPU's delta spent waiting specifically on disk I/O completion, a direct signal that storage latency, not CPU capacity, is the bottleneck for that processor.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.42.2.12.2.2.12.5.1.1.1.7 snmpwalk -v2c -c public <target> KERNEL-READER-SUNMANAGEMENTCENTER-MIB::krCPUTotIOWaitTime
Get a specific instance (index 1):
