Therefore I've written a small entstat-wrapper-shellscript, which excludes the 2 bad devices from being asked. But xymon isn't using my entstat version, but only the /usr/sbin/entstat. I was debugging with truss, but I was not able to find out, which part of xymon is calling /usr/sbin/entstat [xymond_rrd at the server?].

Client-side tools such as those that pick up the network stats are called from the xymonclient-OSNAME.sh script that is part of the client installation. Since these are shell scripts, it should be trivial to modify as needed.
