Software Defined Networking (SDN) makes Internet network configuration easier by separating the control plane and data plane. The control plane on the controller has information on network devices in the data plane and centrally control these devices. One of the controllers in SDN being developed is the Open Network Operating System (ONOS). ONOS provides interfaces such as Representational State Transfer (REST) Application Programming Interface (API). The ONOS core REST API provides some information from the network connected to it, such as devices, statistics, and the information is still JSON file. Based on the previous description, the problems that are the basis of this research can be detailed, namely the unavailability of graphic visualization for the southbound interface on the ONOS controller, the data available on the ONOS controller is still in JSON form, and the visualization of the southbound interface graphic will make it easier for users to see. This study aims to create an interface that facilitates statistical monitoring by displaying it in graphical form, testing the visualization with several tolopogies, and comparing the visualization results of the topology. Interface creation is done by displaying statistical data in the form of a JSON file from the ONOS controller via the REST API to the web interface in graphical form. The visualization performed produces a graph that is in accordance with the statistics of each topology, the statistics displayed are in the form of devices and its ports, and other parameters such as packet sent, packet received, bytes sent, and byte received. The statistical visualization results of the topology are in accordance with the number of connections. The more connection the device has, the greater the statistical indicators recorded on the ONOS controller, and displayed on the web interface.
