System State Group

The Management Information Base (MIB) variables presented in this section enable you to track various attributes that

describe the state of the critical components supported by your system. Components monitored under the System State

Group include power supplies, AC power cords, AC power switches, and cooling devices, as well as temperature, fan,

amperage, and voltage probes.

System State Group Table

The System State Group defines objects in the System State MIB table.

System State Table

The systemStateGlobalSystemStatus variable provides overall system health status and includes rolled-up (that is,

worst) status for Instrumentation and Storage. This variable monitors the overall system health status. It reflects

changes to systemStateChassisStatus variable, which represents Instrumentation health status and

agentGlobalSystemStatus (dcstorag.mib), which represents Storage health status.

The systemStateChassisStatus variable provides the rolled-up health status for the subsystems associated with the

chassis that is represented by the row in the systemStateTable. Changes to the variables in List 1, each of which

indicates the rolled-up health status of all the components of the corresponding subsystem, are reflected in

systemStateChassisStatus variable.

For example, systemStatePowerSupplyStatusCombined provides the rolled up status of all power supplies for the

chassis.

The variables in List 2 provide the health status of each component of the corresponding subsystem. Each octet of the

value represents a component. If a power supply fails, the corresponding entry in

systemStatePowerSupplyStatusDetails, systemStatePowerSupplyStatusCombined, systemStateChassisStatus and

systemStateGlobalSystemStatus transitions to critical.

List 1
