Rate of Increase Threshold

A rate of increase threshold is defined by specifying a maximum acceptable increase in value for selected

sensors and a period of time value. If the value reported by the sensor rises by more than the specified

maximum acceptable increase in less than the specified period of time an alert condition is reported.

To define a rate of increase threshold:

1. Launch the Sensor & Alert Settings task that corresponds to the numeric-based sensor for which

you will define a threshold.

2. Select Rate of Increase Threshold from the Threshold drop box. Any selected devices that have

previously defined rate of increase thresholds will be listed in the Management Devices list.

3. Select the desired threshold operation and targets:

– If you are editing one or more previously defined rate of increase thresholds, select the devices

on which the threshold has been configured from the Management Devices list and then click

Edit.

– If you are defining a new rate of increase threshold click Add. Then, select one or more devices

for which this threshold will be configured, and click Next. Finally, select the sensors on the

selected devices for which this threshold will be configured and then click Next.

4. Type in the Threshold Name field a name for this threshold.

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

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

acceptable change value for the selected sensors. If the value reported by the sensor increases by

more than the Maximum Increase 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 increases by more
