You must therefor have at least one service defined for each host. It can be as simple as a ping service. Since nagios is primarily service based, host checks are only used to determine if an outage is caused by a service being down (I.e. http) or the entire host.

Hi everybody, I'm several problems with Hosts objects : - hosts checks. When no services are defined, no hosts checks are performed. Result : status is "pending" since 2 days, while host is ok and plugin works "by hand" Result 2 : status is "down" since 2 days, while host is ok (IP address that I defined in first move was not the right one..) When and how hosts checks are performed ? - networks outages My configuration : root : "father" of router1 router1 : "father" of host1, host2, router2 router2 : "father" of host3, host4 when router1 is discovered down, a network outage is flaged. -> on status map, a red line links router1 to its hosts "sons". BUT : 1-"sons" host are said ok, 2-no outages are detected about router2 (it's a router1 son) (logical, in my mind, due to 1- .. but no a good thing !) Normal ? - hosts checks when services are down When a host down, I received services alerts for it, and if the downtime is long enough, i receive the host alert. I beleived that when services checks returned a trouble, a host check was performed and if a host problem was detected, only the host notification was sent.. That's not the case ? Is this a configuration problem ?
