Top X per Y - Unique Cross Sectional analysis

Top X/Y Reports allow for a unique cross-sectional reporting analysis.

Top X/Y is very flexible and open to your imagination allowing unprecedented visibility of your network traffic. It can be used to provide simple 'birds-eye' view analytics such as "Show the Top 5 applications and Conversations for each ASN Peer" or more granular identification such as "Show the Top 100 Threat (IPs, Categories, Type) and for each Affected IP".

A simple example of a cross-sectional analysis is an analysis of the Top 10 Applications (X) for each hour (Y) over a Day. In this example (see figure1) below each Application is assigned a distinct color so that it can easily be identified within each hour

The X/Y analytics that are available as Multiview Reports can be identified by the "/" in the Report title.

The graphic display of a Top X/Y is always a Stacked Bar Chart. The colors of the elements of the Stacked bar chart are the "X" items in the report. The "X" and "Y" cross-section can be made up of more than 1 field but there are always only two logical "X" and "Y" cross-sections
e.g. X(1,2) / Y(3,4,5,6)
The "X" elements are the granular details of each "Y" items in a report.e.g.
YXValue
Y1X19
X29
X39
Y2X19
The default X/Y reports or your own unique cross-sectional analytics can be accessed via the left menus or the right click menu. Where the right-click menu is used the meter measurement will follow the current meter sort order.

The Filter allows the creation of a Top X/Y for any two or more fields.

Image

The Forensic screens Filter tab (below the graph) also provides access to the Top N control element enabling on the fly changes to Top N detail.

Image

Where more than 1 field is available the Top N control element provides the ability to change the cross-section.

Image

The Count algorithm is supported in Top X/Y where the X fields has 1 uncounted field.

A number of default X/Y analytic templates are available in the Multiview and in the Forensic left menus. Some examples are shown below:
