3.3 Using the “Is Not Equal To” Trigger Comparison

When configuring a trigger, you can use the is not equal to trigger comparison to tell a trigger to act only if the new event’s attribute values are not equal to the specified values. For example, the following trigger initiates a work item only if the value of the Business Service Name attribute on the new event is not equal to Email Business Service:

When you use the is not equal to trigger comparison, the trigger ignores empty values in the following event attributes:

  • Business Service ID

  • Business Service Name

  • Business Service Role

  • Computer ID

  • Computer Name

  • Knowledge

  • Resource Group ID

  • Resource Group Name

For example, if the Business Service Name attribute in the previous graphic has an empty value, the trigger ignores the event and does not initiate a work item, even though the empty value is not equal to the specified comparison value.

To configure a trigger to initiate work items for events with empty values that do not equal the specified comparison values, create a named event and associate it with the trigger. The following example specifies a named event that matches AppManager events with Business Service Name values not equal to Email Business Service, including empty values:

Where empty represents any text string you do not use when naming your business services.
