The best thing about flowMon is its ability to monitor your application in real-time using different protocols like HTTP, HTTPS etc. And also you can have custom filters on top of that as well. You cannot find something not working with this software so far. If anything goes wrong I would recommend contacting support team at Kemp directly or via their community forum. There are some features which need improvement like filtering by protocol instead of IP address only. This should be made available in future updates. Monitoring web applications over a wide range of protocols.
