•Filter by severity (the ShowCriticalPriority, ShowLowPriority, ShowMediumPriority, and ShowHighPriority properties)

•Filter by area (the AreaFilter and SimpleAreaFilter properties)

•Filter by the CustomFilter property

•Filter by the alarm summary, which is equivalent to the expression "Enabled AND (ConditionActive OR (AckRequired AND NOT Acked))"
