Alarms Menu
Right-clicking an alarm lets you select from the following pop-up menu options:

Event Definition Editor on page 334).

Details to open a Details screen for the entity emitting it. (see

that are informational and are more than a week old. Rather than having to clear them all
individually, you can clear them as a group. Before selecting this menu item, you will need to
