Nagios Web does not see all hosts


I have Nagios monitoring many hosts and reports on all of them; however, when I open the Web page version 2.10 it only sees three hosts. I made some changes and have restarted nagios and was wondering what could be causing this. When I look at the Web page and click on the configuration tab and check out the hosts, it shows all of the hosts. When I click on the “Hosts Detail” link, it shows only three.

When I run nagiostat I get 31 servers.

Any ideas?


I’m not sure, but did you put your hosts in one (or more) hostgroup(s) ?
if not, try:

define hostgroup{ hostgroup_name NAME alias NAME members list_your_hosts_here,comma_separated }
