if you set the log level to `debug' (you need to configure with
--enable-debug to do that), you should see debugging messages as
collectd enters the `handle_putval' function which parses the lines
received by the executed application/script (along with the data that
was actually received).

If you want to report errors from within the application/script, you can
do so by writing to STDERR. (Maybe that's only in 4.5, I'm not sure.)

Does that help?
