I’ve recently upgraded from version 3.0.3 to 3.4.1. After the upgrade, I’ve found a serious problem that I haven’t completely solved yet.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>When using the OCP_daemon, you configure Nagios to forward passive check results by having it write performance data to a named pipe. While on version 3.0.3, all passive check results where being where being written to the perf data named pipe regardless of whether there was performance data or not. Since the upgrade to 3.4.1, check data only gets written to the pipe if the plugin generates perf data. I need all check results, regardless of state to be written to the pipe and forwarded on to the master.
