We are moving a Nagios 1.x setup to Nagios 3.0.6. We have about 550 hosts and some 5000 services. About 3/4 of the way through our migration of config files we noticed that some of our hostgroups are not showing up in the web ui, but I have yet to figure out why. There are certain hostgroups (but not all) that are not displaying and if they are listed in the 'hostgroup_members' directive of another hostgroup it will cause the second hostgroup not to display either. I've tried every combination of member and hostgroup_members that I can think of but so far the only way I can duplicate the problem is use one of the known problem groups. Does anyone know what the logic or rules are that are used to determine if a hostgroup will display in the web ui or not? Any other suggestions on what to try to track this down? Any help is appreciated. Thanks, -greg </BODY> </HTML>
