Trend Reports
Cisco PVM provides dynamic performance reporting capability within the Reports GUI by displaying a
link to a Trend Report on each report pane. The report displays raw data for the selected network
component (such as protocol, host, or interface) with a superimposed line showing the data trend over
time, offering a magnified view of the data flow for analysis of abnormal or problematic patterns.
To see different statistics for the same report displayed as a Trend report, simply click a different metric
within the report display (such as PACKETS or BYTES) and the chart automatically refreshes.
