This component is responsible for loading and executing reports. Because flows aggregate data collected as packets travel across a given port or interface, they can be used as sort of an abbreviation for series of packets travelling between endpoints of interest. Enable NetFlow reporting for traffic from virtual machines connected to a distributed port group or a port. NetFlow Monitor; NTop. This data can be analyzed by specialized applications to extract the source and destination of the traffic, its class of service, and, by extension, the probable causes of many networking issues. It can also display a heat map with the status of the monitored interfaces.

Network administrators who want to monitor the performance of application flows running in their virtualized environment need to enable flow monitoring on a distributed switch. NetFlow is a general networking tool with multiple uses, including network monitoring and profiling, billing, intrusion detection and prevention, networking forensics, and SOX compliance. Developed by Cisco Systems, the NetFlow technology was introduced on their routers to provide the ability to collect data about network traffic as it enters or exits an interface. Those additional tools are included with FlowScan. There are also hardware-specific sensors for switches, routers, and servers. It includes several pie charts with things such as top applications, top protocols or top conversations. But you’re not stuck with built-in reports as the tool also allows administrators to create custom reports to their liking. The NetFlow capability built into the vSphere 5 platform provides visibility into various virtual infrastructure traffic flows such as: The image below shows a distributed switch configured to send NetFlow records to a collector which, in turn, is connected to an external physical network switch. The PRTG Network Monitor from Paessler AG is an all-in-one solution whose primary purpose is monitoring bandwidth utilization. The device preparing flow records normally sends them to the collector when it determines that the flow is finished either through ageing–when there has not been any traffic within a specific timeout–or when it sees a TCP session termination. NetFlow Analyzer determines interface names using SNMP based on Ifindex values, these Ifindex values are assigned to an interface by the device itself. In all, the tool has over 200 different predefined sensors. Network administrators often find that they have either collected too little or too much data.
