### Sensor (entPhysicalDescr)

Textual description of this sensor.

### Threshold Severity (entSensorThresholdSeverity)

Indicates the severity of a threshold.

There are four possible values:

> other

> minor

> major

> critical

### Threshold Relation (entSensorThresholdRelation)

Indicates how the the sensor value (entSensorValue) and threshold value (entSensorThresholdValue) required to trigger an alarm relate to each other. When evaluating the relationship, the sensor value is to the left of this object, whereas the threshold value is to the right.

There are six possible values:

> lessThan

> lessOrEqual

> greaterThan

> greaterOrEqual

> equalTo

> notEqualTo

### Threshold Value (entSensorThresholdValue)

Indicates the value of a threshold.

To correctly display or interpret the value of this object, you must also know the value of entSensorType, entSensorScale, and entSensorPrecision. That said, you can still directly compare entSensorValue with the threshold values provided in entSensorThresholdTable.

### Threshold Evaluation (entSensorThresholdEvaluation)

Indicates the result of the latest evaluation of a threshold. When the value of this object is true, it indicates that the threshold condition is true.

Note: Thresholds are evaluated at the rate indicated by entSensorValueUpdateRate.

### Threshold Notification (entSensorThresholdNotificationEnable)

When the value of this object is true, entSensorThresholdNotifications are generated for a threshold.
