It dawned on me there are regex tools online!

I used above (on PCRE) and came up with this
CLASS=linux EXHOST=%((a|u)*.yyy.xxx)
that seems to be performing as required
I even went back to another grouping and it looks like this is working - using a regexp in HOST and then using the same in EXHOST
HOST=%(as(cop|tpt)hpux[0-9][0-9])
CLASS=hp-ux EXHOST=%(as(cop|tpt)hpux[0-9][0-9])

This seems to be working now.
CLASS=linux EXHOST=%(a*.yyy.xxx)
this did not work EXHOST=%a*.yyy.xxx ... do you need more () when you're using a * ?
I hope EXHOST=%(*.yyy.xxx) works as well because that's what I really need!
If anyone has a good set of RE pattern examples for HOST and EXHOST - or can point me too some - I would be VERY grateful. I have not quite got the hang of it.

In analysis.cfg
I have a CLASS=linux section that works fine. Fine for *our* hosts - the ones we built.
Now I have to monitor a whole datacenter of other linux boxes that do not adhere to *our* standards.
I added the new linux boxes into Xymon with longname ( host.yyy.xxx ) - my hosts are all shortname. Please tell me how I can exclude every linux host ending in yyy.xxx from CLASS=linux.
It is not really practical to list 150 hosts by LONGname in EXHOST.
Fingers crossed that this is possible!
