krNumPhyBlocksRead

Module: KERNEL-READER-SUNMANAGEMENTCENTER-MIB

OID (symbolic): KERNEL-READER-SUNMANAGEMENTCENTER-MIB::krNumPhyBlocksRead

OID (numeric): 1.3.6.1.4.1.42.2.12.2.2.12.5.3.1.1.2

Node type: OBJECT-TYPE

Type: Counter64

Access: read-only

Description: The rate of number of physical blocks read. Number of physical 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 krNumPhyBlocksRead = (Y - X)/(T2 - T1).

What is krNumPhyBlocksRead?

Rate of physical disk blocks read by this CPU between samples, computed per the MIB's (Y-X)/(T2-T1) formula; a rising rate on one CPU while others are flat can point to I/O-bound work pinned to that processor.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.42.2.12.2.2.12.5.3.1.1.2
snmpwalk -v2c -c public <target> KERNEL-READER-SUNMANAGEMENTCENTER-MIB::krNumPhyBlocksRead

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.42.2.12.2.2.12.5.3.1.1.2.1
snmpget -v2c -c public <target> KERNEL-READER-SUNMANAGEMENTCENTER-MIB::krNumPhyBlocksRead.1
