This application contains dashboards for self-service analysis of network logs. The application is meant to be installed on the Splunk search heads where you want to use the network dashboards. The dashboards utilizes the Network Traffic datamodel and macro from the Splunk Common Information Model (CIM), so installing and configuring the CIM application is a good idea, including defining the macro for the Network Traffic datamodel. Some of the panels also use the Splunk Sankey Diagram, so that should be installed as well.
