     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.

[root@fibnob-hilversum nagios]#

nu heb ik zo de inhoud van : escalations.cfg

Code:

define serviceescalation{
        host_name                      fibnob-hilversum 
        service_description            SMTP
        first_notification              2
        last_notification              6
        contact_groups              admin
        notification_interval          0
        }

wie kan me helpen ?

ps. ik maak gebruik van deze handleiding: http://wiki.centos.org/HowTos/Nagios
(systeem: CentOS 4.5)

en toon even de definitie van "fibnob-hilversum" (vermoedelijk in hosts.cfg)...

Code:

# Generic host definitions
define host{
        name                            fibnob-hilversum    ; Generic template name
        notifications_enabled           1               ; Host notifications are enabled
        event_handler_enabled           1               ; Host event handler is enabled
        flap_detection_enabled          1               ; Flap detection is enabled
        process_perf_data               1               ; Process performance data
        retain_status_information       1               ; Retain status information across program restarts
        retain_nonstatus_information    1               ; Retain non-status information across program restarts
        register                        0               ; DONT REGISTER THIS DEFINITION - ITS NOT A REAL HOST, JUST A TEMPLATE!
        }

# This creates a generic template that any host can use.
# Notifies never, checks 15 times before showing critical on CGI interface,

define host{
        name                    basic-host
        use                     generic-host
        check_command           check-host-alive
        max_check_attempts      15
        notification_interval   0
        notification_period     none
        notification_options    n
        register                0
        }

# This creates a generic host that your routers can use
# monitors host(s) 24x7, notifies on down and recovery, checks 15 times before going critical,
# notifies the contact_group every 30 minutes

define host{
        name                    your-routers-host
        use                     generic-host
        check_command           check-host-alive
        max_check_attempts      15
        notification_interval   30
        notification_period     24x7
        notification_options    d,r
        register                0
        }

define host{
        use                     basic-host
        host_name               mymachine1
        alias                   mymachine1
        address                 192.168.100.101
        contact_groups          einsteins
#       notification_options    d,r  #overrides the basic-host option
        }

define host{
        use                     your-routers-host
        host_name               router1
        alias                   router1
        address                 192.168.100.100
        contact_groups          einsteins
        }

En lees nu even de volgende lijn

Code:

        register                        0               ; DONT REGISTER THIS DEFINITION - ITS NOT A REAL HOST, JUST A TEMPLATE!

... en ga dan verder met het configureren van nagios.

Denk eraan dat templates handig zijn, dus je kan dit best even goed overdenken.

en wat nu dan ?

file: escalations.cfg

Code:

define serviceescalation{
        host_name                      fibnob-hilversum
        service_description            SMTP

        contact_groups                  admin
        notification_interval          0
        }

wat heb je aangepast?

wat jij zij...

zet dan nog eens je hosts hier neer... de error is duidelijk, de host die jij opgeeft wordt niet gevonden.

Opzich is jou deel wel goed, het probleem zit hem in het feit dat je de hosttemplate de naam van je server hebt gegeven. Doe het als volgt:

Code:

# Generic host definitions
define host{
        name                            basic-host          ; Generic template name
        notifications_enabled           1               ; Host notifications are enabled
        event_handler_enabled           1               ; Host event handler is enabled
        flap_detection_enabled          1               ; Flap detection is enabled
        process_perf_data               1               ; Process performance data
        retain_status_information       1               ; Retain status information across program restarts
        retain_nonstatus_information    1               ; Retain non-status information across program restarts
        max_check_attempts      15
        notification_interval   30
        notification_period     24x7
        notification_options    d,r
        check_command           check-host-alive
        contact_groups                  XXXX
        register                        0               ; DONT REGISTER THIS DEFINITION - ITS NOT A REAL HOST, JUST A TEMPLATE!
        }

define host{
        use                     basic-host
        host_name               fibnob-hilversum
        alias                   fibnob-hilversum
        address                 127.0.0.1
        }

Je maakt dus eerst een algemene template aan met daarin de instellingen die voor al je hosts moeten gelden, daarna maak je de daadwerkelijke hosts (servers) aan en die laat je de template gebruiken.

Code:

define serviceescalation{
        host_name                      fibnob-hilversum
        service_description            SMTP
        first_notification              2
        last_notification              6
        contact_groups                  admin
        notification_interval          0
        }

na het aanpassen wat jij zij krijg ik deze melding;

na het aanpassen wat jij zij krijg ik deze melding;

Kun je het hele bestandje ergens neerzetten? De tekst die hierboven staat is goed, maar waarschijnlijk heb je ergens een fout gemaakt.

Ik laat mijn collega vanmiddag er wel naar kijken.

Dank jullie voor de hulp.

misschien kunnen jullie hier wat basic bestanden plaatsen zo als die er standaard bij ziiten en kijken of dat werkt...
