14.2.2 History List
On this page, one of the history can be selected to show the relate statistics.
The lower part of this page shows the related statistics information: DropEvents RxOctets,
RxPkts, Broadcast, Multicast, CRC AlignErrors, Undersize, Oversize, Fragments, Jabbers,
Collisions and Utilization.
Take history index 1 as an example, from the history control, it is clear that it is sampled every
5 seconds, and 5 items are collected each time, and only the latest are shown.

Sample Type : Sets the type of sampling, the method of sampling the selected variable and
calculating the value to be compared against the thresholds is as follows: If the value of this
object is absoluteValue (1), the value of the selected variable will be compared directly with
