[Quoted] There are some serious shortcomings of this product.

  1. The security implications of having to / allowing a Network Interface to operate in promiscuous mode (to grab all packets, regardless of destination).
  2. Possibly having to change your DataLink / Physical (OSI Model) network infrastructure, e.g. throw out your switch(s) and replace them with hubs just to get this poor-substitute-for a-real-DBA tool to work.
  3. Advanced Networking Option would give this package a VERY hard time (i.e. it would stop it in its tracks) because packets are encrypted.

Last but not least; any monitoring package can extract performance data (either by measuring response times or by looking at all the dynamic performance views and so on. That's great. But that doesn't actually help you tune the server does it?. To do that takes never ending practice and book-studying.
