cntCpuSemLost
Module: CNTAU-MIB
OID (symbolic): CNTAU-MIB::cntCpuSemLost
OID (numeric): 1.3.6.1.4.1.333.1.1.4.15.1.4
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: The number of semaphores lost for this CPU.
What is cntCpuSemLost?
This read-only INTEGER reports the number of semaphores lost for this CPU. An admin would treat a nonzero or growing value here as a sign of a software or synchronization bug on that processor, since lost semaphores typically indicate resource accounting problems. For example, a CPU showing lost semaphores alongside degraded task performance would be a candidate for a controlled reset.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.333.1.1.4.15.1.4 snmpwalk -v2c -c public <target> CNTAU-MIB::cntCpuSemLost
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.333.1.1.4.15.1.4.1 snmpget -v2c -c public <target> CNTAU-MIB::cntCpuSemLost.1
