nagios host limits

[Conor Shovlin]

Hi Marc,



Here is the config we are adding. These lines cause a perfectly working config (see before) to causing errors(see after).



define host{

        use                     windows-server  ; Inherit default values from a template

        host_name               DCFP01        ; The name we're giving to this host

        alias                   DCFP01        ; A longer name associated with the host

        address                 172.x.x.x    ; IP address of the host

        hostgroups              Dxxx

        parents                 Axxx

        notification_interval   0

        notification_options    d

        }





As you can see there it is a simple host that we are adding but it starts throwing errors. As soon as we remove the host all errors clear and we have no issue. If I remove another host it works.

     Check your configuration file(s) to ensure that they contain valid

     directives and data defintions.  If you are upgrading from a previous

     version of Nagios, you should be aware that some variables/definitions

     may have been removed or modified in this version.  Make sure to read

     the HTML documentation regarding the config files, as well as the

     'Whats New' section to find out what has changed.

No. Several of us are monitoring (10's of) thousands of hosts and

services. You certainly have a real configuration error. If you need

help, post the error and corresponding host and service definitions

and anything else that might seem relevant based on the error.
