Perl and C system programmer - please, see 'Monitorix' at http://www.monitorix.org a pure Perl monitoring solution, see also 'Fiwix' at http://www.fiwix.org a UNIX/Linux-like hobby operating system kernel as a reference. I also work with PHP (Ncurses), Perl and Shell scripting for daily system administration.
