program: Receiving messages from external applications

The program driver starts an external application and reads messages from the standard output (stdout) of the application. It is mainly useful to receive log messages from daemons that accept incoming messages and convert them to log messages.

The program driver has a single required parameter, specifying the name of the application to start.

Declaration

program(filename);

Example: Using the program() driver

source s_program {
    program("/etc/init.d/mydaemon");
};

NOTE: The program is restarted automatically if it exits.
