Description: A table of CODIMA Express History Long Term Segment Database Derived Objects. Based on 15 minute intervals Segment statistics are gathered on the network segment to which the Express is attached. The statistics in this databases are calculated by adding Port 1 statistics and Port 2 statistics together. Port 2 however will only be active if you are using the Express as a dual port analyzer, i.e., monitoring full duplex. The Derived object implements statistics that are derived from other values, e.g., % Utilization, % Error frames. The number of rows in this table is dependant on the value chosen for the Long Term dcTimeSlots object.
