Nagios Core Version 4.1.1 on raspberry

[bdacasc]

Greetings from a Noob

I have followed this guide since I would like to learn some nagios.
It was working then and I could login and see the localhost at the start.
Then I wanted to add another host to be monitored. Another Raspberry pi. I just wanted a simpel ping.

Then I messed up !

What did I do ? I tried to add a jessie.cfg. I wanted to do simpel ping to see if my jessei was alive.

in my nagios.cfg I added
# You can specify individual object config files as shown below:
cfg_file=/usr/local/nagios/etc/objects/commands.cfg
cfg_file=/usr/local/nagios/etc/objects/contacts.cfg
cfg_file=/usr/local/nagios/etc/objects/timeperiods.cfg
cfg_file=/usr/local/nagios/etc/objects/jessie.cfg

this did not work !

When I do

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

Code: Select all

Reading configuration data...
   Read main config file okay...
Error: Template 'generic-contact' specified in contact definition could not be not found (config file '/usr/local/nagios/etc/objects/contacts.cfg', starting on line 29)
   Error processing object config files!

Looking at contacts.cfg :

Code: Select all

# Just one contact defined by default - the Nagios admin (that's you)
# This contact definition inherits a lot of default values from the 'generic-contact'
# template which is defined elsewhere.

define contact{
        contact_name                    nagiosadmin             ; Short name of user
        use                             generic-contact         ; Inherit default values from generic-contact template (defined above)
        alias                           Nagios Admin            ; Full name of user

        email                           @nagios@@localhost      ; <<***** CHANGE THIS TO YOUR EMAIL ADDRESS ******
        }

cat from /usr/local/nagios/var/nagios.log

What have I done wrong?
Command me, dark lords

Hello @bdacasc,

Your contact uses a template called generic-contact and it looks like it cannot locate this.

Error: Template 'generic-contact' specified in contact definition could not be not found (config file '/usr/local/nagios/etc/objects/contacts.cfg', starting on line 29)

Let's verify that you have a templates.cfg in /usr/local/nagios/etc/objects and it contains the generic-contact template.

Code: Select all

define contact{
        name                            generic-contact    	; The name of this contact template
        service_notification_period     24x7			; service notifications can be sent anytime
        host_notification_period        24x7			; host notifications can be sent anytime
        service_notification_options    w,u,c,r,f,s		; send notifications for all service states, flapping events, and scheduled downtime events
        host_notification_options       d,u,r,f,s		; send notifications for all host states, flapping events, and scheduled downtime events
        service_notification_commands   notify-service-by-email	; send service notifications via email
        host_notification_commands      notify-host-by-email	; send host notifications via email
        register                        0       		; DONT REGISTER THIS DEFINITION - ITS NOT A REAL CONTACT, JUST A TEMPLATE!
        }

Next, make sure your nagios.cfg lists the path to the object config file for templates.cfg

Code: Select all

# You can specify individual object config files as shown below:
cfg_file=/usr/local/nagios/etc/objects/commands.cfg
cfg_file=/usr/local/nagios/etc/objects/contacts.cfg
cfg_file=/usr/local/nagios/etc/objects/timeperiods.cfg
cfg_file=/usr/local/nagios/etc/objects/templates.cfg
cfg_file=/usr/local/nagios/etc/objects/jessie.cfg

Run a pre-flight check on your configuration:

Code: Select all

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

If everything checks out, re-start Nagios:

Code: Select all

service nagios restart

Let me know if you get it working.
