System State Group 47

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 will transition to critical, and

systemStatePowerSupplyStatusCombined, systemStateChassisStatus and

systemStateGlobalSystemStatus will all transition to critical.
