Represents a hardware component capable of measuring the characteristics of a physical property (for example, the temperature or voltage characteristics of a computer system).

For a description of the supported properties for the Oracle_Sensor class, see the following table.

Sensor

string

The CreationClassName property is a mandatory key property.

CreationClassName indicates the name of the class or the subclass used in the creation of an instance. When used with the other key properties of this class, this property allows all instances of this class and its subclasses to be uniquely identified.

Set to Oracle_Sensor.

string

The DeviceID property is a mandatory key property.

The DeviceID property indicates an address or other identifying information used to uniquely name the LogicalDevice.

Set to the NAC name of the sensor.

string

The SystemCreationClassName property is a mandatory key property.

Indicates the SystemCreationClassName for the scoping system.

Set to Oracle_ComputerSystem.

string

The SystemName property is a mandatory key property.

Indicates the SystemName of the scoping system.

Set to Oracle_ComputerSystem.Name of the instance of Oracle_ComputerSystem that represents the controllee.

string

The current state indicated by the sensor. This is always one of the PossibleStates.

Value representing current state of the sensor.

string

The ElementName property is a user-friendly name.

This property allows each instance to define a user-friendly name in addition to its key properties, identity data, and description information.

Note that the Name property of ManagedSystemElement is also defined as a user-friendly name. But it is often subclassed to be a key. It is not reasonable that the same property can convey both identity and a user-friendly name, without inconsistencies. Where Name exists and is not a key (such as for instances of LogicalDevice), the same information can be present in both the Name and ElementName properties.

Set to the NAC name of the sensor.

uint16[]

An enumerated value indicating an administrator's default or startup configuration for the enabled state of an element. By default, the element is Enabled (value=2).

The following values apply:

{2, 3, 5, 6, 7, 9, .., 32768..65535}

Definitions for these values are:

{Enabled, Disabled, Not Applicable, Enabled but Offline, No Default, Quiesce, DMTF Reserved, Vendor Reserved}.

Set to default value 2 (Enabled).

uint16[]

Integer enumeration that indicates the enabled and disabled states of an element. It can also indicate the transitions between these requested states. For example, shutting down (value=4) and starting (value=10) are transient states between enabled and disabled. The following values apply:

• 0 (Unknown).

• 1 (Other).

• 2 (Enabled) - The element is or could be executing commands, will process any queued commands, and queues new requests.

• 3 (Disabled) - The element will not execute commands and will drop any new requests.

• 4 (Shutting Down) - The element is in the process of going to a disabled state.

• 5 (Not Applicable) - The element does not support being enabled or disabled.

• 6 (Enabled but Offline) - The element might be completing commands, and will drop any new requests.

• 7 (Test) - The element is in a test state.

• 8 (Deferred) - The element might be completing commands, but will queue any new requests.

• 9 (Quiesce) - The element is enabled but in a restricted mode.

• 10 (Starting) - The element is in the process of going to an enabled state. New requests are queued.

• 11..32767 (DMTF Reserved).

• 32768..65535 (Vendor Reserved).

Appropriate value depending on whether the sensor is enabled, disabled, or unknown.

uint16[]

Indicates the current health of the element. This attribute expresses the health of this element but not necessarily that of its subcomponents. The following values apply:

• 0 (Unknown) - The implementation cannot report on HealthState at this time.

• 5 (OK) - The element is fully functional and is operating within normal operational parameters and without error.

• 10 (Degraded/Warning) - The element is in working order, and all functionality is provided. However, the element is not working to the best of its abilities. For example, the element might not be operating at optimal performance, or it might be reporting recoverable errors.

• 15 (Minor Failure) - All functionality is available, but some might be degraded.

• 20 (Major Failure) - The element is failing. It is possible that some or all of the functionality of this component is degraded or not working.

• 25 (Critical Failure) - The element is nonfunctional, and recovery might not be possible.

• 30 (Non-Recoverable Error) - The element has completely failed, and recovery is not possible. All functionality provided by this element has been lost.

DMTF has reserved the unused portion of the continuum for additional health states in the future.

Appropriate value.

uint16[]

The OperationalStatus property indicates the current statuses of the element.

Various operational statuses are defined. Many of the enumeration's values are self-explanatory.

Enumeration values can include any of the following:

{Unknown, Other, OK, Degraded, Stressed, Predictive Failure, Error, Non-Recoverable Error, Starting, Stopping, Stopped, In Service, No Contact, Lost Communication, Aborted, Dormant, Supporting Entity in Error, Completed, Power Mode, DMTF Reserved, Vendor Reserved}

Possible values for the enumeration values include:

{0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, .., 0x8000..}

Appropriate value.

string

Enumerates the string outputs of the sensor. For example, a switch sensor can output the states On or Off. Another implementation of the switch can output the states Open and Close. Another example is a NumericSensor supporting thresholds. This sensor can report the states like Normal, Upper Fatal, Lower Non-Critical, and so forth. A NumericSensor that does not publish readings and thresholds, but can store this data internally and still report its states.

Appropriate values depending on the type of the sensor.

uint16[]

The RequestedState property is an integer enumeration that indicates the last requested or desired state for the element, irrespective of the mechanism through which it was requested. The actual state of the element is represented by EnabledState. This property is provided to compare the last requested and current enabled or disabled states.

Element definitions include any of the following:

{Unknown, Enabled, Disabled, Shut Down, No Change, Offline, Test, Deferred, Quiesce, Reboot, Reset, Not Applicable, DMTF Reserved, Vendor Reserved}

Values for these definitions include:

{0, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, .., 32768..65535}

Set to 12 (Not Applicable).

uint16[]

The type of the sensor, for example, voltage or temperature sensor. If the type is set to Other, then the OtherSensorType description can be used to further identify the type, or if the sensor has numeric readings, then the type of the sensor can be implicitly determined by the units. A description of the different sensor types is as follows:

• A temperature sensor measures the environmental temperature.

• Voltage and current sensors measure electrical voltage and current readings.

• A tachometer measures speed/revolutions of a device. For example, a fan device can have an associated tachometer that measures its speed.

• A counter is a general purpose sensor that measures some numerical property of a device. A counter value can be cleared, but it never decreases.

• A switch sensor has states like Open or Close, On or Off, or Up or Down.

• A lock has states of Locked or Unlocked.

• Humidity, smoke detection, and air flow sensors measure the equivalent environmental characteristics.

• A presence sensor detects the presence of a PhysicalElement.

• A power consumption sensor measures the instantaneous power consumed by a managed element.

• A power production sensor measures the instantaneous power produced by a managed element such as a power supply or a voltage regulator.

• A pressure sensor is used to report pressure.

The following values apply:

{0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, .., 32768..65535}

Definitions of these values are:

{Unknown, Other, Temperature, Voltage, Current, Tachometer, Counter, Switch, Lock, Humidity, Smoke Detection, Presence, Air Flow, Power Consumption, Power Production, Pressure, DMTF Reserved, Vendor Reserved}

Appropriate value.
