As already pointed out it will help if you gave us the input.

In general however I find it very helpful if I start building regular expressions in parts.

So instead of writing it all out maybe you can start with:
my $prefixSysDescr = "system.sysDescr"; if( $input_var =~ /$prefixSysDescr/ ) { print "Match!\n"; }
Once you are sure that that part works you can then start adding more of what you want matched.

That way you get a clearer idea of where your RegEx is failing - Which I believe is the problem here.
