escalating severity: Information, Warning, Error, Critical, or Failure. By default, the Alert 
Severity generated by this threshold will be “Error.”

– Specify the Alert Profile that will be used to determine what alert notification actions will be

A rate of decrease threshold is defined by specifying a maximum acceptable decrease in value for the 
sensor and a period of time value. If the value reported by the sensor falls by more than the specified 
maximum acceptable decrease in less than the specified period of time an alert condition is reported. To 
define a rate of decrease threshold:

1. Start the Camera Pods, Sensor Pods, or Device Crawlers task by double-clicking on the appropriate 

icon.

2. Click Sensors... to open the Sensor Configuration window.

3. Select from the Sensors selection list the sensor for which you will define a threshold. A list of 

thresholds that have been previously defined for the selected sensor, if any, appears in the 
Thresholds selection list.

4. Click Add... to open the Select Threshold window. Select Rate of Decrease Threshold and then 

click OK to close the Select Threshold window.

6. Specify Basic threshold settings. From the Basic tab in the Thresholds pane:

a. Type in the Maximum Decrease field (or use the arrows in the field to specify) the highest 

acceptable change value for the selected sensor. If the value reported by the sensor decreases by 
more than the Maximum Decrease value in a period of time that is equal to or less than the 
number of seconds specified in the Time Period field, an alert condition results.

b. Type in the Time Period field (or use the arrows in the field to specify) the number of seconds 

that defines the unacceptable change period. If the value reported by the sensor decreases by 

The Alert Profile drop box will appear in the Advanced tab only if additional 
Alert Profiles have been created. For more information see “Creating an Alert 
Profile” on page 63.
