Choosing the best NetFlow analyzer available depends on the needs of the IT team that is supporting your company's critical business applications, since they know the attributes specific to your software that require monitoring. Although these requirements are often nearly the same across applications, in some cases there are also a few unique metrics that, if monitored correctly, can benefit the support team.

Best NetFlow Analyzer
