krCPUKernelModeTime
Module: KERNEL-READER-SUNMANAGEMENTCENTER-MIB
OID (symbolic): KERNEL-READER-SUNMANAGEMENTCENTER-MIB::krCPUKernelModeTime
OID (numeric): 1.3.6.1.4.1.42.2.12.2.2.12.5.1.1.1.5
Node type: OBJECT-TYPE
Type: DisplayString
Access: read-only
Description: Time spent by CPU in kernel mode in percentage of CPU delta. If V1 is the previous value of kernel mode time and V2 is the current value of kernel mode time then krCPUKernelModeTime = ( V2 - V1 ) * 100 / krCPUDelta .
What is krCPUKernelModeTime?
Percentage of this CPU's delta spent executing in kernel mode (system calls, interrupt handling, etc.); persistently high kernel time relative to user time can indicate excessive syscalls, driver overhead, or interrupt storms.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.42.2.12.2.2.12.5.1.1.1.5 snmpwalk -v2c -c public <target> KERNEL-READER-SUNMANAGEMENTCENTER-MIB::krCPUKernelModeTime
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.42.2.12.2.2.12.5.1.1.1.5.1 snmpget -v2c -c public <target> KERNEL-READER-SUNMANAGEMENTCENTER-MIB::krCPUKernelModeTime.1
