Types of statistics

The data tables in the statistics dialog boxes list the counters, or categories of statistics being gathered, for the specified object. For example, the categories for ports include Interface, Ethernet Errors, Bridge, and Rmon. Each category can be associated with six types of statistics. Table 10 describes the types of statistics that are available.

Table 10 Types of statistics

Statistic	Description
AbsoluteValue	The total count since the last time counters were reset. A system
	reboot resets all counters.
Cumulative	The total count since the statistics window was first opened. The
	elapsed time for the cumulative counter is displayed at the bottom of
	the graph window.
Average	The cumulative count divided by the cumulative elapsed time.
Minimum	The minimum average for the counter for a given polling interval over
	the cumulative elapsed time.
Maximum	The maximum average for the counter for a given polling interval over
	the cumulative elapsed time.
LastValue	The average for the counter over the last polling interval.

Types of graphs

With Device Manager, you can create line, area, bar, and pie graphs. Figure 10, Figure 11, Figure 12, and Figure 13 illustrate the different graph styles, respectively.
