Select a Different View

In the Top Ten window ( show screen), you can view a variety of reports, such as a report of network efficiency and bytes saved by compression. You can also change the number of classes displayed.

To select a different view in the Top Ten window:

1. Click the Top Ten tab.

2. In the View top field, enter the number of classes you want to view in the report (default is 10). To view all classes, clear this field so that it's blank.

Note: If you don't want to change the view (the next step), you must click update to see the revised list.

3. Select the desired view:

View Description
Average Rate
The classes with the highest average bandwidth rate in the designated time interval; measured in bits per second (the default report type)
Peak Rate The classes with the highest peak bandwidth rate in the designated time interval; measured in bits per second
Total Bytes The classes with the highest total bandwidth consumed in the designated time interval; measured in bytes
Network Efficiency The classes with the most retransmissions (that is, the lowest network efficiency)
Average Rate, Precompressed with % Bytes Saved The classes with the highest precompression average rate for compressible traffic, along with the percentage of bytes saved from compression. This list is sorted by rate — the classes with the highest precompression average rate appear at the top of the list.
Compression % Bytes Saved The classes with the highest percentage of bytes saved, due to compression, in the designated time interval. The Compression % Bytes Saved value is calculated by subtracting precompression bytes (the size without any compression) and postcompression bytes (the size after compression) and dividing this difference by precompression bytes. Note that only compressible traffic is considered in these calculations.
Compression Bytes Saved

The classes in which compression offered the most bytes savings. For each class, this view lists the number of bytes that didn't have to traverse the link, because compression was used.

4. Make sure the time period is appropriate and change it if necessary. See Select the Time Period.

5. To print the new report, click print.

Getting More Details About Top Classes

The reports on the Top Ten page include a few ways to drill down and get more information about each class.

  • Next to each class name is a graph icon . When you click this icon, a report containing two or three graphs pertaining to the class appears in its own window. For example, if you are viewing the Network Efficiency report and click the graph icon next to the HTTP class, a Class Details report appears with an Average and Peak Rates graph and a Network Efficiency graph of the HTTP class. Note that the graph icon appears to the left of the column heading (Top Ten - Average Rate, for instance) as well. Clicking this icon displays stacked charts of the top ten classes.

  • Each class name is a hyperlink. When you click the class name, the Traffic Class page for that class appears so that you can check settings or make modifications.
