"nagios doesn't like monitoring hosts without services"?


#1

In /etc/nagios3/conf.d/hostgroups.cfg I see a note stating:

[code] # nagios doesn’t like monitoring hosts without services, so this is

a group for devices that have no other “services” monitorable

(like routers w/out snmp for example)

define hostgroup {
hostgroup_name ping-servers
alias Pingable servers
members gateway
}
[/code]

Is this statement necessary? I have included all non-services hosts (printers and upstream routers, mainly) in this section. The only result of doing this, as far as I can see, is that if one of these hosts goes offline I get TWO alerts (one host alert, one service alert).

Do I really need to include these non-services hosts in this way? What harm could I cause by having only host definitions for these hosts?

nagios SHOULDN’T send service notifications for a host which is down… i have no way of testing this at this time… so i can’t help on this, latest release still has the same problem. :frowning:
