“Change,” when the packet presence changes from being present to
not present or vice versa, and “DataChange,” which triggers when the
packet presence remains the same, but the data within the packet has
changed. The events are evaluated on a per–field basis. After select-

General Alarms category that can be used to get an overview of possible
