Daily Event Rate Report Trending Reports
5-2 Enterasys IPS Analysis and Reporting Guide
Figure 5-1 Daily Event Rate Report
The Columns represent the total events for a time period, typically a day. However, the time
periods shown by the columns at the start and end of the chart are segmented to add up to 24
hours based on the time the report was displayed. For example, in
Figure 5-1 , the column on the
left represents the event count for 10/22/2010 starting at 2:45:53 PM, while the column on the right
represents the event count for 10/29/2010 ending at 2:45:53 PM. At the top of the window, the
generation time for the report is displayed.
Hovering the mouse over a column displays the total event count and the event count change
from the prior time period. The text boxes displaying this information are bordered in green if the
event count increased and in red if the event count decreased.
The teal horizontal line represents the average event count over the period and the vertical blue
line represents the moving average. You can change the number of days used for the moving
average by clicking on the up or down arrows next to the
Days in Moving Average field.
Selecting a Display Type
The Daily Event Rate tab can display data as a Table, Column chart, Bar chart, or Pie chart. You can
interactively change the chart type by clicking on the chart type icons at the top of the windows.
On some charts you can select the Logarithmic button to display the data in Logarithmic scale. The
following graphic illustrates the different chart types.
