Specifying Rules for an Alert Definition

Rules are the conditions that alerts check for in order to determine when to issue messages. These are similar to the rules used in entry/exit systems except that there is only one set of rules.

 

An alert is generated based on a list of one or more rules. The rules are formulas which return non-zero values when a condition is true and zero when a condition is not true. To specify how these rules should be combined, use the Generate this alert combo box, which has the following values.

·      When all of these rules are true.

This value indicates that this alert should be generated only when all of the rules in the list return a non-zero value.

·      When any of these rules are true.

This value indicates that this alert should be generated when one or more of the rules in the list return a non-zero value.

·      When any of these rules are not true.

This value indicates that this alert should be generated when one or more of the rules in the list return zero.

·      When none of these rules are true.

This value indicates that this alert should be generated only when all of the rules in the list return zero.

Adding New Rules

To add a new rule for when to generate a signal, press the Add… button. This will display the Modify Rule Dialog where you can enter the formula for the rule.

Ä    Note: Typically, a rule should return a non-zero value in order for a signal to be generated. This can be modified by changing the value for when to generate this signal.

Modifying Existing Rules

To modify an existing rule, select the rule from the rule list, then press the Edit… button. This will display the Modify Rule Dialog where you can modify the selected rule.

 

To remove an existing rule, select the rule from the rule list, then press the Remove button. Your action will be confirmed and the rule will be removed.

What Do I Do Next?

If you are creating a new alert definition, press the Next button to continue on to the Enter Message page. If you would like to exit the wizard without creating a new alert definition, press the Cancel button. If you would like to change the name of the alert, press the Back button to return to the Basic Information page.

 

If you are finished updating the rules of a previously created alert definition, press the OK button to save your changes or select another property page. If you would like to exit from this dialog without performing any changes, press the Cancel button.

Ä    Note: Alert definitions require at least one value rule before they can be saved.
