The best thing about kali tool it's easy way we can monitor our application easily without any technical knowledge or expertise in networking area. Also there are many plugins that help us monitoring different aspects like network traffic analysis etc., But one problem i am facing when using this software its need more memory so if u want try new features then better use 32 bit only not 64bit version as they have some limitation while running their tools.(For example) If my cpu has 4 cores but still having 8 GB RAM than how will be possible? So always check before downloading anything from internet specially those which require high resources such as java virtual machine(JVM). Network Traffic Analysis & Monitoring:- This feature helped me during development process where ever needed data regarding performance issues were found out quickly through proper documentation.- Easy Way To Monitor Our Application- Very Simple UI.
