I have nagiostat installed & configured, but in its debug log, it appears as though nagiostat is somehow not seeing a few fields (including the check's output). The Nagios GUI definitely DOES show the check's output, so I don't understand why nagiostat is not able to see it. Since perf-data and output are both missing, nagiostat has nothing to record.

There must be something simple that I'm missing, but I'm having a hard time pinning it down. Does anyone have any ideas about what might be happening here?
