Hope it helps and makes it into the next release of check_traffic…. <<<<make_config script>>>> #!/usr/bin/perl # # make-config - Part of check_traffic plugin. # # Copyright (c) 2003 Adrian Wieczorek, <ads (at) irc.pila.pl> # # See README file for more details. $VERSION = "0.90b"; $HOSTNAME = "ENTER YOUR HOSTNAME"; # Hostname of monitoring host.
