Werner is right here - the "%" must be first, it's only mission is to
tell Hobbit to treat this as a regular expression instead of a simple
text string.
For debugging regular expressions, I routinely use the info-page
display (which shows clearly whether a host/test is matched or not),
but also the "pcretest" tool that comes with the pcre library. Like
this:
$ pcretest
PCRE version 4.5 01-December-2003
re> /nyc(app1|dc1|dc2|ex1|ex03|fs1|fs2|time).domain.com/
data> nycdc2.domain.com
0: nycdc2.domain.com
1: dc2
data> nycdc4.domain.com
No match
