krNumOfDirBlocksRead
Module: KERNEL-READER-SUNMANAGEMENTCENTER-MIB
OID (symbolic): KERNEL-READER-SUNMANAGEMENTCENTER-MIB::krNumOfDirBlocksRead
OID (numeric): 1.3.6.1.4.1.42.2.12.2.2.12.5.5.1.1.12
Node type: OBJECT-TYPE
Type: Counter64
Access: read-only
Description: The rate of number of directory blocks read. Number of directory blocks read 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 krNumOfDirBlocksRead = (Y - X)/(T2 - T1).
What is krNumOfDirBlocksRead?
Rate of directory blocks read on this CPU, indicating how much of the I/O load is directory-traversal work rather than regular file data reads.
Examples
