Filter Alarms Using the Equipment Tree-view

For alarm pages with the equipment tree view pane, you can filter the alarm display list to show alarms belonging to selected parent and child equipment branches. If no equipment is selected in the tree-view then all alarms are displayed.

To select equipment, check the box to the left of the relevant branches. If you select equipment with child branches, then the child equipment will be selected and grayed out.

Note: If the parent equipment branch is checked, child equipment cannot be deselected.

If the parent is not selected, you can change the checked states of the child equipment.

Next to each item in the tree, an alarm count is displayed. The count includes the total number of alarms belonging to the equipment and its child hierarchy. The type of alarms that are counted vary according to the type of alarms that are displayed on the list. For example, on the active alarms page, the count represents the active alarms associated to that equipment, while on the disabled alarms page, the count represents the disabled alarms associated to that equipment. Other points to consider with the equipment count include:

1. The count on the tree node represents the total number of alarms that are associated with that equipment.

2. For alarms that are not associated to equipment, the count is not available due to the nature of the equipment tree view.

3. The counts are not affected by the filter applied to the alarm list.

4. Due to point 2 and 3, the total sum of the counts from the equipment tree does not equal to the alarm count on the alarm banner, and they never mean to be comparable. The alarm count on the banner represents the total number of (unfiltered) unacknowledged alarms in the system (subjected to the viewable areas of the currently logged on user).
