Maybe you could just export those data into Excel files (any other format
will do), and provide a download link to those file. Those files could be

Mark, I'm using netstat as follows. You can see the tomcat process listening
on 8443 and all the incoming requests in TIME_WAIT. These connections do get
cleared after the default timeout of 60 seconds, my intention is to refuse
creating them in the first place.

I remember a more or less public discussion some time ago, that the
acceptCount setting is virtually worthless, because modern kernels
simply ignore it.

P.S. By ignore I mean that ServerSocket.accept(100) has no effect.

You'd have to do something pretty strange with symbolic links for an
