Network Statistics

Home > Quickstart > Network Statistics

The MaaTec Network Analyzer offers two different network statistics views. The standard Statistics View is described here. It displays the current network load as well as the cumulated data volume and maximum network load per address, network card, protocol, connection, or a combination of these. This information is presented in a table based view as text, numerical values, or as horizontal bar graph.

The Pro version of the Network Analyzer does also offer a Network Load over Time Statistics View. It presents the network load per address, protocol, etc. as line or bar chart with a history over a configurable period of time. The Load over Time Statistics are described in detail on the next page.

You can use the Statistics View to view at different aspects of the data traffic in your network. Use the New Statistics toolbar button , the File > New Statistics menu command or press Ctrl+T on the keyboard to open the Settings dialog for the Statistics View. To change the settings for an open statistics view use the Collect > Capture Settings menu command.

Open the Statistics page of the Settings dialog. You can use the other pages in the dialog to configure filters that will restrict the packets that are evaluated for the statistics display. This works in the same way as the capture filter for collecting packets and is described in detail later on.

On the Statistics page you can choose between different statistics modules to analyze your network traffic. A detailed description of the different modules can be found on the Statistics Modules page. Select the statistics module 'Internet Traffic per System and Protocol' in group E) (if you switched off the Easy Statistics Mode in the Tools menu the module is called 'L3 Addr Higher Protocol Statistics'). This will fill the list on the left with the available display values (columns) for this module. The table on the right contains the chosen display values with some additional properties. Each of these values will be displayed in its own column in the Statistics View. This connection is shown in the image below.

To add more values, select one or more elements in the value list and click the Add button. The new values will be added to the column list right after the currently selected item in this list. To remove items from the column list, select them and click the Remove button. To change the sequence of items in the column list, select one and use the Up and Down buttons to move the item up and down.

To get useful traffic graphs, you may need to modify the Max values of columns that are set to a graphic format (e.g. Bar). If you want to analyze a 10 MBit network, choose values that use MBit/s units and set the Max value to 10. If you want to look at traffic on a DSL connection, choose columns that use KBit/s units and set the Max value according to your connection speed (e.g. 768 for sent and received, and 896 for total data rates).

When your column list contains at least one address, one protocol, and one value column, click OK. This will create a new Statistics View that contains all selected columns.

The Network Analyzer will usually start to collect data now. If the Auto-Start Collection option in the Tools Menu was disabled, you need to click the Start button in the toolbar, use the Collect > Start menu command, or press F8 on the keyboard. If there is any traffic on your network, new data rows will be added to the view, displaying which address causes how much traffic using which protocol. You can sort the data by clicking on any column header. Clicking once will sort text columns in ascending order and numeric columns in descending order. If you click the header of a sorted column again the sorting order will be reversed.

You can use the Window > New Window menu command to open additional windows that contain the same statistics. Each of these views can be sorted by a different column. So you can open two Statistics Views, use the Window > Tile command to display one above the other, and then sort one of them for received and the other for sent data.

If you want to use the data in some other application, you can copy the content of the table as tab separated value list to the clipboard. Therefore click the copy button , use the Edit > Copy menu command, or press Ctrl+C or Ctrl+Insert on the keyboard. Most spreadsheet applications (e.g. Microsoft Excel) will correctly insert this format into a table when you paste it.

You can at any time click the Empty Buffer button or use the Collect > Empty Buffer menu command to reset the statistics view and delete all data rows.

Click the Stop button , use the Collect > Stop menu command, or press Ctrl+F8 on the keyboard to freeze the current statistics display.
