The Hardware Management Agent uses the Sun HW Trap MIB to implement SNMP traps. These traps are used to report the environmental state of the Sun x64 Server as well as faults, errors, and other conditions affecting hardware components.
The SNMP traps are categorized into three groups. Any SNMP trap name ending in Ok or Error, as well as any SNMP trap name containing Threshold, is reporting a change in a sensor value.
Any SNMP trap name ending in Fault is reporting a problem detected by the system's fault management subsystem, if such a subsystem is available on the server.
The final group is the status SNMP traps, which report the environmental state and any hardware information that is not covered by the two previous groups.
