krNumOfCPUMig
Module: KERNEL-READER-SUNMANAGEMENTCENTER-MIB
OID (symbolic): KERNEL-READER-SUNMANAGEMENTCENTER-MIB::krNumOfCPUMig
OID (numeric): 1.3.6.1.4.1.42.2.12.2.2.12.5.6.1.1.4
Node type: OBJECT-TYPE
Type: Counter64
Access: read-only
Description: The rate of number of CPU migrations by threads. Number of CPU migrations by threads 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 krNumOfCPUMig = (Y - X)/(T2 - T1).
What is krNumOfCPUMig?
Rate at which threads migrated between CPUs from this processor; a high migration rate can hurt cache locality and may indicate the scheduler's load balancing is fighting an unbalanced workload.
