Re: Excluding one filesystem from a threshold but not all

I don't think you can filter large filesystems.


But you could create threshold configurations which filter against categories. Those should work out of the box.
Just put your nodes into the corresponding category.
But there is one issue: https://issues.opennms.org/browse/NMS-9811
