[Xymon] Ignoring a Service

[David Baldwin]

All,

It's not a problem preventing functionality in this case, but % patterns
match using regular expressions not wildcards.

The patterns aren't anchored by default (i.e. they match a substring),
so in fact the pattern %(server*|server2*) will match any name which
includes the string "serve" (optionally followed by 0 or more "r"
characters) or "server" (optionally followed by 0 or more "2"
characters) - which is already matched by the first pattern. So for
example "abcserve123" will match.

If you wanted to do anchored matching (i.e. not substrings) then the
following regular expression would be the equivalent for a wildcard pattern:
%(^server.*|^server2.*)
 or more compact:
%^server2?.*

http://www.regular-expressions.info/ is a useful resource
