1description: > 2 Implement to provide performance loss class sensor thresholds. Objects 3 implementing Sensor.Threshold.PerformanceLoss must be instantiated in the 4 correct hierarchy within the sensors namespace. The following sensor 5 hierarchies are recognized: 6 airflow 7 altitude 8 current 9 energy 10 fan_tach 11 humidity 12 power 13 pressure 14 temperature 15 utilization 16 voltage 17 18 Additionally, any object implementing Sensor.Threshold.PerformanceLoss must 19 also implement Sensor.Value. 20 21properties: 22 - name: PerformanceLossHigh 23 type: double 24 default: NaN 25 description: > 26 The upper bound of the warning threshold. A value of 'NaN' is used to 27 indicate there is no threshold of this type. 28 - name: PerformanceLossLow 29 type: double 30 default: NaN 31 description: > 32 The lower bound of the warning threshold. A value of 'NaN' is used to 33 indicate there is no threshold of this type. 34 - name: PerformanceLossAlarmHigh 35 type: boolean 36 description: > 37 True if the sensor value has exceeded the defined bound. False if the 38 sensor value has not exceeded the defined bound. 39 40 PerformanceLossAlarmHigh may be set to False to clear an alarm 41 condition. The behavior of setting PerformanceLossAlarmHigh to True is 42 undefined. 43 - name: PerformanceLossAlarmLow 44 type: boolean 45 description: > 46 True if the sensor value has exceeded the defined bound. False if the 47 sensor value has not exceeded the defined bound. 48 49 PerformanceLossAlarmLow may be set to False to clear an alarm 50 condition. The behavior of setting PerformanceLossAlarmLow to True is 51 undefined. 52signals: 53 - name: PerformanceLossHighAlarmAsserted 54 description: > 55 The high threshold alarm asserted. 56 properties: 57 - name: SensorValue 58 type: double 59 description: > 60 The sensor value that triggered the alarm change. 61 - name: PerformanceLossHighAlarmDeasserted 62 description: > 63 The high threshold alarm deasserted. 64 properties: 65 - name: SensorValue 66 type: double 67 description: > 68 The sensor value that triggered the alarm change. 69 - name: PerformanceLossLowAlarmAsserted 70 description: > 71 The low threshold alarm asserted. 72 properties: 73 - name: SensorValue 74 type: double 75 description: > 76 The sensor value that triggered the alarm change. 77 - name: PerformanceLossLowAlarmDeasserted 78 description: > 79 The low threshold alarm deasserted. 80 properties: 81 - name: SensorValue 82 type: double 83 description: > 84 The sensor value that triggered the alarm change. 85
