Top Applications

The Applications tab shows you the top applications and top protocols for the selected time period. The default view shows the Top ApplicationIN Report. This report shows the distribution of incoming traffic application-wise.

Choose between IN and OUT to display the application-wise distribution of incoming or outgoing traffic respectively.

The Time Period box lets you choose between last hour, last day, last week, last month, and last quarter's traffic graphs. The From and To boxes let you choose custom time periods for the graphs. Use the icon to select the date and time easily. The time period for these graphs is based on the current system time. Once you select the desired date and time, click the Show button to display the appropriate application traffic report.

The table below the graph shows the distribution of traffic per application. You can see what application caused how much traffic, and how much of the total bandwidth was occupied by that application.

The Show Ports Link next to an application name indicates that that application is not identified by NetFlow Analyzer. When you click on Show Ports Link, a window opens up showing the port and protocol details for this application. If it is a valid application you can then add it to the list of applications in the Application Mapping page.

The Show Ports Link will be displayed next to an unknown application only in the Last Hour report.

Click on an application's name to see the Top Conversations that contributed to this application's traffic.

The Show box above this table lets you choose how many applications need to be displayed. You can set the maximum value for this option from the Settings page.

The pie chart below this table shows what percentage of bandwidth is being used by each application. The icon above the pie chart lets you see the pie chart enlarged in a new window. From here, you can click the icon to save the pie chart as a PDF file.

Viewing Top Protocols

Click the icon or the Protocol Distribution link to see the top protocols for the selected interface or IP group, in a new window.

Choose between IN and OUT to display the protocol-wise distribution of incoming or outgoing traffic respectively.

This report sorts traffic based on the protocol used, while the Application IN/OUT Report sorts traffic based on the application, i.e., the combination of port and protocol.

Click on a protocol's name to see the Top Conversations that used this protocol. The Show box above this table lets you choose how many applications need to be displayed. You can set the maximum value for this option from the Settings page.

The pie chart below this table shows what percentage of bandwidth is being used by each protocol. The icon above the pie chart lets you see the pie chart enlarged in a new window. From here, you can click the icon to save the pie chart as a PDF file.
