This lowers the total number of flow updates per second needed to monitor high-volume networks. Sampling will only use 1 in every N packets, thus skipping many flows. The bigger each individual traffic session is, the higher the bandwidth will be you can monitor with 50,000 flow updates per second.įinally, if you enable sampling in your NetFlow exporters you will be able to monitor much more bandwidth. This answer may vary, however, if you are monitoring a server-centric network in a datacenter, where each flow may be much larger or smaller, depending on content served. Keep in mind that these are very rough estimates. To ensure that you are using the latest features and enhancements, we have decided to sunset LogicMonitor REST API v1 and v2. Since then, all enhancements and fixes are done only to API v3. Meaning 50,000 flow updates per second would equate to monitoring 10Gbps of traffic. In the second half of 2022, we started supporting LogicMonitor REST API version 3 (referred as API v3). In our experience monitoring regular user networks (using google, facebook, etc) an average flow update encompasses roughly 25kbytes of transferred data. However, if you are asking how much bandwidth you can monitor with 50k netflow updates per second, the answer becomes more complex. If you used NetFlow v9 which uses a template based format it might be a bit more, or less, depending on what is included in the template. An add-on to Network Performance Monitor (NPM), NetFlow Traffic Analyzer (NTA) allows you to capture data from continuous streams of network traffic and. This means you'd use about 20Mbps to carry the flow packets. Most applications and appliances list flow volume per second, so you are asking what the bandwidth requirement is to transport 50k netflow updates per second:įor NetFlow v5 each record is 48 bytes each with each packet carrying 20 or so records, with 24 bytes overhead per packet.
