Analytics: WAN Insight

Feb 07, 2017

The NetScaler SD-WAN WAN optimization (WO) appliances optimize the delivery of a large number of applications through the WAN, by improving the efficiency of data flow across the network between the datacenter and the branch sites. WAN Insight analytics enable administrators to easily monitor the accelerated and unaccelerated WAN traffic that flows between the datacenter and branch WAN optimization appliances. WAN Insight provides visibility into clients, applications and branches on the network, to help troubleshoot network issues effectively. Live and historical reports enable you to proactively address issues, if any

Enabling analytics on the datacenter WAN optimization appliance enables the NetScaler Management and Analytics System (MAS) to collect data and provide reports and statistics for the datacenter and the branch WAN optimization appliances.

     4.  From the Action drop-down, select Enable Insight.

     5.  Select the following parameters as required:

          *  Geo data collection for HDX Insight: Shares client IP address with the Google Geo API.

          *  AppFlow: Starts collecting data from WAN optimization instances.

               -  TCP and WANOpt: Provides TCP and WANOpt Insight reports.

               -  HDX: Provides HDX Insight reports.

               -  TCP only for HDX: Provides TCP only for HDX Insight reports.

To view WAN Insight reports:

     1.  In a web browser, type the IP address of the NetScaler Management and Analytics System (for example, http://192.168.100.1).

     2.  In the User Name and Password fields, enter the administrator credentials.

     3.  Navigate to Analytics > WAN Insight.

Note

The WAN Insight option is visible only after you add an SD-WAN WO instance to NetScaler MAS.

     You can view the following reports:

          *  Applications - Displays the usage and performance statistics of all the applications for the selected duration.

          *  Branches - Displays the usage and performance statistics of all the WAN optimization branch appliances.

          *  Clients - Displays the usage and performance statistics of all the clients accessing the WAN optimization appliances, in each branch.
