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.
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.
