krNumOfRegWinSysUndrFlow

Module: KERNEL-READER-SUNMANAGEMENTCENTER-MIB

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

OID (numeric): 1.3.6.1.4.1.42.2.12.2.2.12.5.7.1.1.5

Node type: OBJECT-TYPE

Type: Counter64

Access: read-only

Description: The rate of number of register window system underflows. Number of register window system underflows 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 krNumOfRegWinSysUndrFlow = (Y - X)/(T2 - T1).

What is krNumOfRegWinSysUndrFlow?

Rate of kernel-mode register window underflow traps on this CPU, the system-mode counterpart to krNumOfRegWinUsrUndrFlow.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.42.2.12.2.2.12.5.7.1.1.5
snmpwalk -v2c -c public <target> KERNEL-READER-SUNMANAGEMENTCENTER-MIB::krNumOfRegWinSysUndrFlow

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.42.2.12.2.2.12.5.7.1.1.5.1
snmpget -v2c -c public <target> KERNEL-READER-SUNMANAGEMENTCENTER-MIB::krNumOfRegWinSysUndrFlow.1
