Nagios Startup Errors

[Carroll, Jim P [Contractor]]

I think your config is suffering from recursion.

On the one hand, you've given freelinuxcd.org the name of generic-host, and
2 lines later, you're telling Nagios to refer to the generic-host definition
for the details.

Not related to this issue, your check_command is incorrect.  You're
specifying the command here, when you should be referencing a token in
checkcommands.cfg.

If I may...?  Try this instead:

define host{
        name                            generic-host
        notifications_enabled           1
        event_handler_enabled           1
        flap_detection_enabled          1
        process_perf_data               1
        retain_status_information       1
        retain_nonstatus_information    1
        register                        0
        }

define host{
        use                     generic-host
        host_name               freelinuxcd.org
        alias                   Free Linux CD Project Server
        address                 131.161.247.80
        check_command           check-host-alive
        max_check_attempts      10
        notification_interval   120
        notification_period     24x7
        notification_options    d,u,r
        }

Some notes:

1) You've got low_flap_threshold and high_flap_threshold set... I don't
believe these directives exist in any host/service definition (but I'm sure
someone will correct me if I'm wrong)... however, there are names similar to
these in nagios.cfg, which is where they belong.

2) The address *must* be the IP address, if you're to use it at all.
Extrapolating from your example, I would guess that you're relying on DNS to
do the hostname resolution.  In that case, remove the 'address' line
altogether.  (It also frees you up in case someone renumbers that hostname.
But there are other issues to concern yourself with if you go that route...
for now, just try the above trivial case just to get it working.  You can
fine tune later.)

Anyway, try the above on for size.  If it works, great.  If you're surprised
that it works, go back and read over the documentation to find out why.

HTH.
