krNumOfCopyOnWriteFaults
Module: KERNEL-READER-SUNMANAGEMENTCENTER-MIB
OID (symbolic): KERNEL-READER-SUNMANAGEMENTCENTER-MIB::krNumOfCopyOnWriteFaults
OID (numeric): 1.3.6.1.4.1.42.2.12.2.2.12.5.9.1.1.5
Node type: OBJECT-TYPE
Type: Counter64
Access: read-only
Description: The rate of number of copy-on-write faults. Number of copy-on-write faults 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 krNumOfCopyOnWriteFaults = (Y - X)/(T2 - T1).
What is krNumOfCopyOnWriteFaults?
Rate of copy-on-write faults on this CPU, occurring when a process writes to a shared page (e.g., after a fork()) and the kernel must duplicate it; a common and usually benign event tied to process-creation activity.
