I like that it allows you to see where there are issues in your network, as well if they're affecting performance or availability of services for end users -- this is really useful information! It's also pretty self-explanatory; all necessary settings can be set up easily without needing any help from an IT professional (I've never had problems using their "step by step" tutorial). There could always have been more options available - but overall we haven't found anything too bad about netflow optimzer so far either!! We use flow visibility extensively throughout our business operations here at work, which helps us track down networking bottlenecks quickly when needed most urgently during busy times such as Black Friday etc., allowing me/us time back into working with other important matters rather than troubleshooting ongoing outages caused mostly due technical reasons relating specifically towards infrastructure limitations within networks & data centers across multiple locations worldwide.
