krNumOfIvolCSwitches
Module: KERNEL-READER-SUNMANAGEMENTCENTER-MIB
OID (symbolic): KERNEL-READER-SUNMANAGEMENTCENTER-MIB::krNumOfIvolCSwitches
OID (numeric): 1.3.6.1.4.1.42.2.12.2.2.12.5.6.1.1.2
Node type: OBJECT-TYPE
Type: Counter64
Access: read-only
Description: The rate of number of involuntary context switches. Number of involuntary context switches is calculated at different times which is either when refresh interval reaches or when the mannual refresh is issued. If at time T1 the value is X and at time T2 the value is Y then krNumOfIvolCSwitches = (Y - X)/(T2 - T1).
What is krNumOfIvolCSwitches?
Rate of involuntary context switches on this CPU, i.e. threads preempted rather than voluntarily yielding; a high rate suggests CPU contention forcing the scheduler to interrupt running threads.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.42.2.12.2.2.12.5.6.1.1.2 snmpwalk -v2c -c public <target> KERNEL-READER-SUNMANAGEMENTCENTER-MIB::krNumOfIvolCSwitches
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.42.2.12.2.2.12.5.6.1.1.2.1 snmpget -v2c -c public <target> KERNEL-READER-SUNMANAGEMENTCENTER-MIB::krNumOfIvolCSwitches.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> krNumOfIvolCSwitches.1
