"grep pnsca nagios.log" should produce:
[1222364357] Event broker module '/usr/local/nagios/lib/pnsca.so' initialized successfully.

If you don't have that, decipher the error messages in
the log until you get it.

If you're already getting that, but it doesn't work
anyway, you can try using the shipped send_nsca script
instead of the one on your system. If you change the
third line of it to say "cat > /tmp/pnsca.out", all the
host and service check results the module receives from
Nagios will be dumped to /tmp/pnsca.out (worst case
scenario, you could actually do
  tail -f /tmp/pnsca.out | send_nsca -f send_nsca.cfg
and get pretty much the same benefit, but Nagios will
crash when /tmp/pnsca.out gets larger than 4GB).

It's also a rather good idea to make sure that send_nsca
is always running (use Nagios and check_procs for this).
With pnsca in place, you should always have exactly one
send_nsca process running on your system. If that one dies,
you need to restart Nagios (until I've got time to add some
sort of clever process control in the module, anyways). If
you have too many, something else is going wrong, so you'll
need to check that up manually.

Thanks for testing, and good luck :)
