| Implement to provide performance loss class sensor thresholds. Objects |
| implementing Sensor.Threshold.PerformanceLoss must be instantiated in the |
| correct hierarchy within the sensors namespace. The following sensor |
| hierarchies are recognized: |
| airflow |
| altitude |
| current |
| energy |
| fan_tach |
| power |
| pressure |
| temperature |
| utilization |
| voltage |
| |
| Additionally, any object implementing Sensor.Threshold.PerformanceLoss must |
| also implement Sensor.Value. |

| properties: |
| - name: PerformanceLossHigh |
| type: double |
| default: NaN |
| description: > |
| The upper bound of the warning threshold. A value of 'NaN' is used |
| to indicate there is no threshold of this type. |
| - name: PerformanceLossLow |
| type: double |
| default: NaN |
| description: > |
| The lower bound of the warning threshold. A value of 'NaN' is used |
| to indicate there is no threshold of this type. |
| - name: PerformanceLossAlarmHigh |
| type: boolean |
| description: > |
| True if the sensor value has exceeded the defined bound. |
| False if the sensor value has not exceeded the defined bound. |
| |
| PerformanceLossAlarmHigh may be set to False to clear an alarm |
| condition. The behavior of setting PerformanceLossAlarmHigh to True |
| is undefined. |
| - name: PerformanceLossAlarmLow |
| type: boolean |
| description: > |
| True if the sensor value has exceeded the defined bound. |
| False if the sensor value has not exceeded the defined bound. |
| |
| PerformanceLossAlarmLow may be set to False to clear an alarm |
| condition. The behavior of setting PerformanceLossAlarmLow to True is |
| undefined. |
