krNumOfRegWinUsrOvrFlow

Module: KERNEL-READER-SUNMANAGEMENTCENTER-MIB

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

OID (numeric): 1.3.6.1.4.1.42.2.12.2.2.12.5.7.1.1.2

Node type: OBJECT-TYPE

Type: Counter64

Access: read-only

Description: The rate of number of register window user overflows. Number of register window user overflows 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 krNumOfRegWinUsrOvrFlow = (Y - X)/(T2 - T1).

What is krNumOfRegWinUsrOvrFlow?

Rate of user-mode register window overflow traps on this CPU, a SPARC architecture-specific counter reflecting how often user code exhausts its register window stack and must spill to memory.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.42.2.12.2.2.12.5.7.1.1.2
snmpwalk -v2c -c public <target> KERNEL-READER-SUNMANAGEMENTCENTER-MIB::krNumOfRegWinUsrOvrFlow

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.42.2.12.2.2.12.5.7.1.1.2.1
snmpget -v2c -c public <target> KERNEL-READER-SUNMANAGEMENTCENTER-MIB::krNumOfRegWinUsrOvrFlow.1
