I have the following in alerts.cfg
HOST=%sciv2-ws* 

The problem is that it is picking up a host called

sciv2-wdl2-hqd01
Is it me or the regex ?Has this been fixed  in newer versions ?
Thanks !

It's you.  The "s*" in your regular expression matches zero or more "s" at
that location.  The hostname you give contains zero "s" at that point,
which matches the expression.

Michael,

Perhaps you are thinking “glob” patterns, like the ones used with directory listings. Regular expressions are different. “*” doesn’t mean any sequence of characters, but zero or more of the preceding character. Google “regular expressions”. Xymon uses perl-style regular expressions.
