There's no direct way to do a != on XMH_* fields (although this is
something that should be added, to be honest), however you can either
check for the contents of the tag itself, or use the old filter pipeline
approach.

Unfortunately, the actual *calculation* of the NOPROP.* effects is done
entirely within xymongen, not xymond, so matching tests, wildcards,
includes and excludes would have to be done by hand.


This one will give you all those with any values there at all:

xymon localhost 'xymondboard color=red XMH_NOPROPRED=.'


This works for any xymon-xmh(5) tag; these can also be used in field
output, so you can also just examine the entire (parsed) config line:

xymon localhost 'xymondboard color=red fields=hostname,test,XMH_RAW' |
grep -i -v noprop
