I can seem to get the hang of this.

HOST=* EXHOST=iadccmp1,iadccmp2,apaccmp1,apaccmp2,%stn380esx.*

Doesn't work.  Does the % have to be at the beginning? Does EXHOST not work for it? Of course, what I really want is:

HOST=* EXHOST=%(iad|apa)ccmp.*,%stn380esx.*

That didn't work either.

If you are going to do a regx, you have to use %.   I see you are 
missing it for your HOST
Try:

HOST=%* EXHOST=%(iadjapa)ccmp.*,%stn380esx.*

I think it's all or nothing with regexp.

Try:

HOST=* EXHOST=%(iadccmp1|iadccmp2|apaccmp1|apaccmp2|stn380esx.*)

Yes, this.  Paraphrasing the man page for analysis.cfg, the target string
is exactly one of:
(a) comma-separated list of hostnames
(b) "*" to indicate "all hosts"
(c) a Perl-compatible regular expression

Pick one.  You're trying to mix these and it won't work.
HOST=%* EXHOST=%(iadjapa)ccmp.*,%stn380esx.*
This won't work because "*" is not a valid regular expression in the HOST=
part.  But the "%" should not be needed there because HOST=* matches item
(b).

David's example should work for you because it's one single regular
expression - item (c).
