krNumLogBlocksRead
Module: KERNEL-READER-SUNMANAGEMENTCENTER-MIB
OID (symbolic): KERNEL-READER-SUNMANAGEMENTCENTER-MIB::krNumLogBlocksRead
OID (numeric): 1.3.6.1.4.1.42.2.12.2.2.12.5.3.1.1.4
Node type: OBJECT-TYPE
Type: Counter64
Access: read-only
Description: The rate of number of logical blocks read. Number of logical 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 krNumLogBlocksRead = (Y - X)/(T2 - T1).
What is krNumLogBlocksRead?
Rate of logical (filesystem-level, cache-eligible) blocks read by this CPU; comparing this to krNumPhyBlocksRead shows how much of the read workload the buffer cache is absorbing versus hitting physical disk.
