ssCpuRawSoftIRQ
Module: UCD-SNMP-MIB
OID (symbolic): UCD-SNMP-MIB::ssCpuRawSoftIRQ
OID (numeric): 1.3.6.1.4.1.2021.11.61
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The number of 'ticks' (typically 1/100s) spent processing software interrupts.
This object will not be implemented on hosts where the underlying operating system does not measure this particular CPU metric.
On a multi-processor system, the 'ssCpuRaw*' counters are cumulative over all CPUs, so their sum will typically be N*100 (for N processors).
What is ssCpuRawSoftIRQ?
This OID is a running counter of the number of clock ticks, typically hundredths of a second, the CPU has spent processing software interrupts, summed across all CPUs on multi-processor systems. An admin graphs the rate of change of this counter to see what share of CPU time is going to softirq handling, useful when diagnosing network-driver or interrupt-heavy workloads.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2021.11.61 snmpwalk -v2c -c public <target> UCD-SNMP-MIB::ssCpuRawSoftIRQ
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.2021.11.61.1 snmpget -v2c -c public <target> UCD-SNMP-MIB::ssCpuRawSoftIRQ.1
