Top Applications


The Applications tab displays all the applications that pass through a specific interface for a selected period of time. Choose between IN and OUT to display the application-wise distribution of incoming or outgoing traffic respectively. The default view of the application report shows Traffic IN details. The applications, for the ease of monitoring can be grouped as application groups and top-sites.

Applications Report

The report shows application-wise distribution of incoming and outgoing traffic. The list of applications are ordered to show the top applications that contribute to maximum network traffic along with the volume of traffic and the total percentage of network traffic it occupies.  Clicking on the application name will open the detailed report of all the conversations. The conversations detail report lists the number of resources accessed the specific application. It gives the details of the conversation like source, destination, application type, Ports involved, Protocol, DSCP, volume of traffic, and the perecentage of traffic the specific conversation contributes.  The pie-graph below the table gives a quick view about the top applications and the percentage of traffic it occupies in the network.  

 

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.

 

Note 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 Zoom icon above the pie chart lets you see the pie chart enlarged in a new window. From here, you can the export as a PDF, CSV file or email the report by going to the "Actions" button on top and selecting as per your requirement

Applications Group

This report displays different applications that are grouped together for the ease of view. This feature enables you to group the applications as a single entity.

 

Creating an application group:

To create applications group click "applications / QoS maps"

  1. Select Application Group
  2. Click on "add" to create a new application group
  3. Specify the group name, a description about the group and select the applications you want to group together
  4. Click "save" to view the application group.

Now, a new application group has been created.

 

Top Sites

This report displays the applications contributing to the maximum network traffic.

 

top sites

 

Expanding the applications displays name of the website (if the DNS is resolved) and names of top 10 machines in your network (if the DNS is resolved) connecting to that website. It will also give the contribution of traffic in terms of upload & download volume (and % of total traffic) from each IP address to the particular site through that application. You can also view the total traffic percentage across each application. The report gives a detailed view about the traffic in terms of upload & download volume and percentage of total traffic from each IP address to the specific site via the application. Further drill-down to the website name gives you information on the upload or download traffic detail and the specific IP address that accessed that site.

 

Adding a sub application:

 

The "Add Sub App" options allows you to add a sub application to the list of applications under top sites tab. By this way you can add a name to the IP address, range, or network and associate it with an application name. This helps identify the IP network, range or address that has accessed a particular application.

 

 

Viewing Top Protocols

Click on 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.

 

Note

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 Enlarge icon above the pie chart lets you see the pie chart enlarged in a new window. From here, you can the export the report as a PDF, CSV file or email the report by going to the "Actions" button on top and selecting as per your requirement.

 

Support for Internet Protocol Version 6(IPV6)

IP version 6 (IPv6) is a new version of the Internet Protocol, designed as the successor to IP version 4 (IPv4). IPv6 increases the IP address size from 32 bits to 128 bits, to support more levels of addressing hierarchy.

 

NetFlow Analyzer now offers support for IPV6. You can view the raw data records for the last two hours in IPV6 format. since the IPV6 addressing format yet to be adapted by most people worldwide we are offering support for IPV6 format only at raw data level. The raw data collected for top ten applications, source, and destination for the past two hours can be viewed in IPV6 format.

 

You can also view the raw data of Troubleshoot Reports in IPV6 format.
