Use
The Test Event widget can be used to trigger, with a single click, an Event previously created in the configuration. This Test Event is intended to alert a Recipient Group according to an Alarm Schedule or to trigger an alarm cascade to test if it runs correctly when the event actually occurs.
The prerequisites for this are created Recipients, a Recipient Group, an Alarm plan, an Event and an Event Category.
