Module: HEALTH-MONITOR-SUNMANAGEMENTCENTER-MIB
OID (symbolic): HEALTH-MONITOR-SUNMANAGEMENTCENTER-MIB::hmSpinsOnMutexes
OID (numeric): 1.3.6.1.4.1.42.2.12.2.2.11.2.1.1
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: Sum of spins on mutexes (lock not acquired on first try) for all CPUs.
What is hmSpinsOnMutexes?
The sum, across all CPUs, of the number of times a kernel mutex lock was not acquired on the first try and the CPU had to spin waiting for it. Sustained high values point to kernel lock contention that can slow down the whole system under load.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.42.2.12.2.2.11.2.1.1 snmpwalk -v2c -c public <target> HEALTH-MONITOR-SUNMANAGEMENTCENTER-MIB::hmSpinsOnMutexes
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.42.2.12.2.2.11.2.1.1.1 snmpget -v2c -c public <target> HEALTH-MONITOR-SUNMANAGEMENTCENTER-MIB::hmSpinsOnMutexes.1
