Network ports of a filer are not always in use. Up to now, the NetPort
check would send an alarm for every port that was not marled as up. Of course, this is not useful for ports that have been deactivated on purpose. Previously, these ports could be excluded from being monitored using the switch exclude and --include and their respective names. The problem with this solution is that, should any of these ports be activated at a later stage, they will no longer be monitored - except if the storage admin tells the monitoring admin to adjust the configuration. The switch --ignore_disabled offers a new solution, where the configuration no longer needs to be changed. The check decides on its own, that network interfaces administratively marked as down should be excluded from the monitoring process. This switch will be available in version 3.3.1.
