linux client disk warning levels

I've got some linux clients set up and I'd like to adjust the disk warning levels, but I can't seem to get any custom settings to work.  There's settings in the /etc/xymon/localclient.cfg file, but editing the defaults does nothing.  In that file it specifies that I need to add --local to the xymonclient.sh command found in the /etc/xymon/cllientlaunch.cfg file, but when I do that the client goes purple.  So I looked in the /etc/xymon/localclient.cfg file again and added a HOST= line as well as the custom disk levels I want, but that doesn't change anything.  I should also note that I'm restarting the xymon-client service after each change to make sure it's applying it.

Can someone give me a clue as to how to make this seemingly simple adjustment on my client?  Or is there a way to define the disk levels in my server's hosts file for this client?

Thanks.
