Numeric alarm thresholds
Numeric alarm thresholds are thresholds defined for sensors that report numeric values.There are nine specific types of numeric thresholds that can be set on numeric sensors.
Numerical threshold options
- The Other Numerical Sensors and Other State Settings options, and for some third-party devices, Voltage, can be used to set threshold settings at a NetBotz device for the full SNMP support devices it monitors.
- All threshold options except Dew Point can be used to define threshold settings the Data Center Expert server will use to monitor its full SNMP support devices.
Threshold | Description |
---|---|
Air Flow | Settings for sensors that measure air movement as feet per minute.
Note
Sensors that use a different measurement, such as cubic feet per minute (CFM) will be displayed under the Other Numeric Sensors option. |
Audio | Settings for sensors that measure the volume of sound. |
Current (Amps) | Settings for sensors that measure current as total amperage (amps). |
Dew Point | Settings for sensors that measure dew point as degrees Fahrenheit (°F) or Celsius (°C). |
Energy (kWh) | Settings for sensors that measure energy consumption as kilowatt hours (kWh). |
Humidity | Settings for sensors that measure relative humidity as a percentage (%). |
Other Numeric Settings | Settings for sensors that measure numeric settings not reported for other Thresholds options. |
Power (VA) | Settings for sensors that measure power as total Volt-amperes (VA) or kiloVolt-amperes (kVA).
Note
Sensors that measure power as a percentage of VA will be displayed under the Other Numeric Sensors option. |
Power (Watts) | Settings for sensors that measure power as total watts (W) or kilowatts (kW). |
Temperature | Settings for sensors that measure temperature as degrees Fahrenheit (°F) or Celsius (°C). |
Voltage | Settings for sensors that measure either AC or DC voltage as total volts (V). |
Numerical threshold types
Setting | Description |
---|---|
Minimum Value Threshold | An alarm occurs when the sensor's value is below the Minimum setting. |
Maximum Value Threshold | An alarm occurs when the sensor's value is above the Maximum setting. |
Range Threshold | An alarm occurs when the sensor's value is outside the range defined by the Minimum and Maximum settings. |
Below Value for Time Threshold | An alarm occurs if the sensor value is below the Minimum setting for longer than the delay in the Time Allowed Below Minimum setting. |
Above Value for Time Threshold | An alarm occurs if the sensor value is above the Maximum setting for longer than the delay in the Time Allowed Above Maximum setting. |
Rate of Increase Threshold | An alarm occurs if the sensor value increases by more than the Maximum Increase setting since the last time the sensor value was sampled. For example, at a sensor that measures amps, 1 would result in an alarm when the amps measured by the sensor increases by one amp. |
Rate of Decrease Threshold | An alarm occurs if the sensor value decreases by more than the Maximum Decrease setting since the last time the sensor value was sampled. For example, at a sensor that measures total watts (W), 100 would result in an alarm when the watts measured by that sensor goes down 100 watts. |
