We’ve compiled this list of some of the very best NetFlow collectors and analyzers that can be used with VMware but also with any networking equipment supporting that technology. NTop is an opensource tool that provide network visibility and by leveraging packet captures and NetFlow information. The ManageEngine NetFlow Analyzer gives the network administrator a detailed view of network bandwidth utilization as well as traffic patterns. The table below gives the features available under each plan. The Netflow Analyzer is a passive application, it listens to incoming flows and captures them for analysis, therefore a NetFlow collector IP address and a listening port must be specified. Consequently, VMware has this to say in the ESX v3.5 documentation: “NetFlow on ESXServer embeds the virtual switch ID into the engineType and engineID fields of the header of each NetFlow export packet. The tool comes with several very useful pre-built reports that are specifically tailored for specific purposes such as troubleshooting, capacity planning or billing. The blue dotted line with an arrow clearly shows that the NetFlow session is established to send flow records for the NetFlow collector for analysis. We’ll assume that if you’re reading this, you already know what VMware is and are familiar with its virtual networking components. SolarWinds is one of the best-known makers of network and system administration tools. NetFlow Analyzer, primarily a bandwidth monitoring tool, has been optimizing thousands of networks across the World by giving holistic view about their network bandwidth and traffic patterns. These features make it a useful tool for network administrators. Analysis can be used for, Intra-host virtual machine traffic (which is virtual machine–to–virtual machine traffic on the same host), Inter-host virtual machine traffic (which is virtual machine–to–virtual machine traffic on different hosts), Virtual machine to physical infrastructure traffic. Except in large, multi-site environments, the flow collectors where the records are sent are also the flow analyzers. 26 Sep 2017 Manish Jha. NetFlow-enabled routers export traffic statistics as NetFlow records which are then collected by a NetFlow collector.

The free version is limited to 10 thousand flows per second and it will only keep raw flow data for 5 hours but it should be more than enough to troubleshoot network issues. 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. Remove All Products Add Product Share. NetFlow Analyzer gives detailed information on network bandwidth utilization pattern for traffic analysis, capacity planning and making policy decisions. This component is responsible for loading and executing reports. Analyze virtual machine IP traffic that flows through a vSphere Distributed Switch by sending reports to a NetFlow collector. One last major component is RRDtool, a popular tool for storing data in round-robin databases and plotting that data on graphs, which is used to store flow information and produce useful graphs. As a bonus, the too has excellent integration with Cisco devices, with support for adjusting traffic shaping and/or QoS policies right from the tool.
