Option Description
rows: K Consider maximum number of events to attribute, excluding events of types specified in ExcludedEventTable, which means assigning attributions to at most K effective events before current impact event.
seconds: K Consider maximum time difference between current impact event and earliest effective event to attribute.
rows: K &seconds: K2 Consider both constraints and comply with stricter one.
