Managing hosts

Nagios offers several pages that can be used to view and modify host information. The Nagios web interface offers a view of all defined hosts, their statuses, and basic information. These can be used to determine the statuses of hosts. Hostgroup-related views also show the statuses for services bound to hosts. Host information pages also offer modifying several parameters related to host configuration.
