krNumOfxcalls
Module: KERNEL-READER-SUNMANAGEMENTCENTER-MIB
OID (symbolic): KERNEL-READER-SUNMANAGEMENTCENTER-MIB::krNumOfxcalls
OID (numeric): 1.3.6.1.4.1.42.2.12.2.2.12.5.6.1.1.5
Node type: OBJECT-TYPE
Type: Counter64
Access: read-only
Description: The rate of number of xcalls to other CPU. Number of xcalls to other CPU 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 krNumOfxcalls = (Y - X)/(T2 - T1).
What is krNumOfxcalls?
Rate of cross-calls (xcalls) issued to other CPUs from this CPU, used by the kernel for cross-processor operations like TLB shootdowns; an unusually high rate can itself become a scalability bottleneck on large multiprocessor systems.
