I've tried your sample script and it worked without a problem for me. So
the script output should be fine.

Debugging output is disabled at compiletime, unless you use
``--enable-debug'' when running the configure script. Then you should
get debugging output like this:
-- 8< --
 [2007-11-10 10:33:15] exec plugin: exec_read_one:
   buffer = qcaste01/cpu-0/cpu-idle N:2299388
 [2007-11-10 10:33:15] plugin: plugin_dispatch_values:
   time = 1194687195; interval = 10; host = qcaste01; plugin = cpu;
   plugin_instance = 0; type = cpu; type_instance = idle;
-- >8 --

This sounds very weird and I have no idea what might be the problem
here.. Could you please re-compile with debugging output and then but a
couple of lines (500 or so should be sufficient) on a webserver
somewhere?

Without an output plugin such as `rrdtool' or `csv' nothing will be
written to disk. But since you say that other metrics are getting
written I assume you have one of these loaded, too..
