Thethreshold-value1 argument ranges from 0 to 2,147,483,647.event-entry1: Index of the event entry corresponding to the upper threshold, in therange of 1 to 65,535.falling_threshold threshold-value2: Specifies the lower threshold. Thethreshold-value2 argument ranges from 0 to 2,147,483,647.event-entry2: Index of the event entry corresponding to the lower threshold, in therange of 1 to 65,535.owner text: Specifies the owner of the entry.
