View source for Monitor your fax queue with Nagios

This is a plugin that can be used with Nagios, a service and host monitoring program. See http://www.nagios.org/ for more info on how to set up Nagios.

This perl script requires the Net::FTP module, but I think this comes standard with perl these days. If not, go to http://search.cpan.org/ and find it there.

Save this file as check_hylafax in your plugins folder (usually /usr/lib/nagios/plugins or /usr/local/nagios/libexec), and make sure it is executable.
