First off, please read writeup formatting tips to see how you can make your messages much more readable.

Most of these options look like they're likely candidactes for exisiting network/system management tools, which would imply you would like to be able to start command line tools and maybe process their output.

For running an external program and capturing its output, take a look at system, the section on qx/STRING/ in perlop and perlopentut.

Processing the output can take many forms, but regular expressions are usually a very handy. Also note that the perltoc manpage will list the full table of content for all the standard perl manpages (LOTS!). If you don't have man on your system use "perldoc", as in perldoc perltoc.

Good luck.
