Dell Command | Monitor Version 9.1 SNMP Reference Guide

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, cooling devices, temperature, fan, amperage, and voltage probes.

The SystemStateGlobalSystemStatus variable provides overall system health status and includes rolled-up (that is, critical) status for Instrumentation and Storage. This variable monitors the overall system health status. It reflects changes to SystemStateChassisStatus variable, which represents Instrumentation 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.
