Nagios 3.x hostgroups member wildcards



Is it possible to have members in hostgroups have wildcards, like router* ? I have just “members " for the group covering everything, but am trying to make a new group just including routers and when I try "members router” there it said it can’t find any matching hosts when the config is verified.

I have the first use regexp option set to 1 in nagios.cfg. Haven’t tried it with true regexp yet.
