here's a probe you can use to run Nagios/Netsaint-checks via a nimsoft probe.
It is multithreaded and can multiple checks in parallel (not really multithreading but multiforking actually as we don't have multithreading in the nimsoft perl).
Please see the attached manual for info on how to use it.
Also, the probe comes with a sample config and a dummy-script to test it.
Please post all enhancements or -requests here, I will post updated versions of the probe here as well.
