should trigger an alert if the size is greater than zero and not only if the size is greater than one.
It though also could be viewed as the latter cited documentation is correct (compared to the implementation) and the example is wrong. But that means that the implemented and documented syntax is so utterly inituitive that even the official examples get it wrong.
So please fix this properly by correcting the unintuitive implementation. If that may take a while, please update for the next 4.x.y release at least the example and add a note that despite ">" is written, "?" (or ">=") is meant and that this issue will be fixed in a later release.
P.S.: I ran into this issue with the (security-patched) Xymon 4.3.28 version in Debian 10 Buster (current stable), but was also able to reproduce this on a test machine with Debian Unstable and Xymon 4.3.30 (as packaged by Debian), so the issue still seems to be present.
