I agree with the others, the default values are pretty low and may not 
work for your situation.  The absolute best way to determine what works 
for you is to simply run the xymon client for a while (days/weeks/etc.) 
and see where your server(s) tend to operate normally and what happens 
when things aren't going well.   After you gather that data, you will 
have a good idea of what you can use for yellow and red thresholds.
