krNumberOfDevInterrupts
Module: KERNEL-READER-SUNMANAGEMENTCENTER-MIB
OID (symbolic): KERNEL-READER-SUNMANAGEMENTCENTER-MIB::krNumberOfDevInterrupts
OID (numeric): 1.3.6.1.4.1.42.2.12.2.2.12.5.4.1.1.4
Node type: OBJECT-TYPE
Type: Counter64
Access: read-only
Description: The rate of number of device interrupts. Number of device interrupts 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 krNumberOfDevInterrupts = (Y - X)/(T2 - T1).
What is krNumberOfDevInterrupts?
Rate of device interrupts serviced by this CPU, useful for spotting an interrupt storm from a misbehaving or overloaded device (e.g., a NIC under heavy traffic) pinned to that processor.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.42.2.12.2.2.12.5.4.1.1.4 snmpwalk -v2c -c public <target> KERNEL-READER-SUNMANAGEMENTCENTER-MIB::krNumberOfDevInterrupts
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.42.2.12.2.2.12.5.4.1.1.4.1 snmpget -v2c -c public <target> KERNEL-READER-SUNMANAGEMENTCENTER-MIB::krNumberOfDevInterrupts.1
