The problem I see in what you are trying to do is that there is no way to determine when exactly a disconnect will be taking place.
 If you know exactly when a disconnect will take place then it should be fairly simple to script it but if the disconnects take
place randomly there is no way you'll be able to script it.  You would have to have a program (daemon) running with hooks into the
network stack that reported statistics at the time of the disconnect and I don't think that's easy to do and certainly would require
an in depth knowledge of programming at the driver level to do it.
