![]() Once the dashboard is created, you will have graphical representations of specific data for quick analysis of the network traffic and informational awareness. Run any query using the NFA Data Explorer, save your query as a widget, and add it to the dashboard of your choice. NFA supports customized widgets and dashboards with a large selection of sophisticated filters and metrics. Highly flexible reporting options are another key point where NFA excels. With more than two terabytes per second peak processing performance for a single DB query, obtaining even the most complex query results is a matter of seconds for NFA. The performance of the entire ecosystem is important as well. NFA is simple and works right out of the box, automatically detecting devices exporting flows within your network. It usually takes no more than 15 minutes. The first what you notice when you install NFA is how easy and fast the deployment process is. But now, let us brag a little and explain why Noction’s Flow Analyzer is a top product that is very well suited to your long-term business needs. These free products are often limited by the length of the retention period or the supported flow collection rate.Īs we have already pointed out, most of the free versions of NetFlow analyzers essentially become demo versions after a predetermined period of time. However, they are limited in some way, e.g., by the number of supported interfaces or flow exporters, or they no longer support all features such as archive reports or historical flow statistics. After 30 days, they automatically revert to the watered-down version and continue to function. “Free” NetFlow monitoring tools are mostly trial software they are fully functional but only for a certain period of time, e.g., 30 days. There is one more important fact that we should mention. After all, it is in the company’s interest to have its product support these new versions and implementations and thus be more competitive. It should also be mentioned that new NetFlow versions and their implementations are typically added early in commercial NetFlow analyzers. These are the hidden costs associated with maintenance. On the other hand, your investment in maintaining the product is likely to grow in the future. On the one hand, you can easily add new features to the code or fix bugs if needed because the source code is publicly available. At the very least, your IT team will be dealing with numerous security updates to the underlying software on which the open source NetFlow analyzer is built. The first rule of programming, “If it works, don’t touch anything” simply does not work in this case. Therefore, you must rely heavily on a team of experienced administrators to maintain your product. Any update may pose a potential risk that the product will stop working. There may be compatibility issues with existing software or hardware or with future updates. In the case of even the best open-source NetFlow analyzers, you have no guarantee that the software will perform as you wish in your network. You do not wait days or weeks and, in some cases even years, for a fix or patch. You paid for the product, so you are entitled to support. You do not have to browse internet forums for hours and rely on the advice of anonymous volunteers with different levels of knowledge. Have you ever found that a network usage reported by your commercial NetFlow analyzer does not match the actual values or that software contains bugs? No worries, there is a single point of contact for any of these issues. Pricing is based on annual subscriptions and on a one-time license basis and support is extended via email, FAQs and phone.Proprietary versus Open-Source NetFlow Analyzers ![]() NetFlow Traffic Analyzer lets businesses integrate the system with several internal applications including SolarWinds IP Address Manager, SolarWinds Network Configuration Manager and SolarWinds User Device Tracker.
