Formatted inputs are simple Perl scripts. That is, MainView Middleware Monitor does not support Perl modules (for example, CPAN installed modules). You cannot directly use the Perl keywords use or require. They do not work in the formatted input for MainView Middleware Monitor.

They are only for parsing incoming text and outputting text in a form suitable for the rest of the event action (execute program, send e-mail, and so on).
