Error in a simple config on Nagios Core 4.4.3

[mpedros]

Hi:

I just installed the version of Nagios Core 4.4.3, make a very simple configuration and I can not find the error ...

Configure 1 single host with only one service:

root@debianNC:/usr/local/nagios/etc/objects# cat oficina.cfg
define host{
use generic-host
host_name FIREWALL
alias Firewall
address 192.168.6.1
}
define service{
use generic-service
host_name FIREWALL
service_description Ping
check_command check_ping!60.0,5%!100.0,10%
}
root@debianNC:/usr/local/nagios/etc/objects#

Add the file "oficina.cfg" to the file "nagios.cfg":

# 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/oficina.cfg

And when verifying it gives me the following errors:

root@debianNC:/usr/local/nagios/etc# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/objects/oficina.cfg

Check your configuration file(s) to ensure that they contain valid
directives and data definitions. 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.

Can someone help me that I can not identify the error?

Thank you very much in advance!

Error: Cannot open config file '/usr/local/nagios/etc/objects/baxo.cfg' for reading: No such file or directory
Error: Invalid max_check_attempts value for host 'FIREWALL'

What is the output of this command:

Code: Select all

ls -l /usr/local/nagios/etc/objects

Try changing it to:

Code: Select all

define host {
use generic-host
host_name FIREWALL
alias Firewall
check_interval 5
max_check_attempts 5
retry_interval 1
address 192.168.6.1
}

Ssax:

I add a test that I did, the same configuration in the Nagios Core of my house works well, the only difference is that I have the version Nagios Core 4.4.0, will there be a problem with version 4.4.3? Attached captures:

Home Config:




Office config:


Thanks,

Martin Pedros

Lets reset the permissions on the config file and make sure there are not any hidden characters in the file.
Run this as root to do that.

Code: Select all

chown nagios.nagios /usr/local/nagios/etc/objects/oficina.cfg
cmmod 664 /usr/local/nagios/etc/objects/oficina.cfg

Install the dos2unix application on the server and run this to clear then out.

Code: Select all

dos2unix /usr/local/nagios/etc/objects/oficina.cfg

See if that helps.

If not, can you get all of the config files from the server, zip them up and upload them to the post so we can view them?
The error may be coming from the template file.

Hi Tgriep:

The commands did not work for me. I attach the requested files.

Thanks in advance!

Martin Pedros

[tgriep]

Thanks for the files.
In the oficina.cfg file you are specifying a template called generic-networking-device but that template does not exist is any of the other templates.

Edit the template.cfg file and add this example to it. Save it and restart nagios to see if it runs now.

Code: Select all

define host {
  name                           generic-networking-device           ; The name of this host template
  use                            generic-host                        ; This template inherits other values from the generic-host template
  check_command                  check-host-alive                    ; Default command to check Linux hosts
  check_interval                 5                                   ; Actively check the host every 5 minutes
  check_period                   24x7
  contact_groups                 admins                              ; Notifications get sent to the admins by default
  max_check_attempts             5
  notification_interval          120                                 ; Resend notifications every 2 hours
  notification_options           d,u,r                               ; Only send notifications for specific host states
  notification_period            24x7
  register                       0                                   ; DONT REGISTER THIS DEFINITION - ITS NOT A REAL HOST, JUST A TEMPLATE!
  retry_interval                 1                                   ; Schedule host check retries at 1 minute intervals
}

Hi Tgriep:

Sorry for the delay. I've tried it and it's the same error. In the next few days I will be a bit complicated to move forward with the tests, if you want to close this case. As soon as I can, I will resume the tests. Thank you very much for all the support.

Regards,

Martin Pedros

One more thing to try.
You have this configuration file in the nagios.cfg

Code: Select all

cfg_file=/usr/local/nagios/etc/objects/baxo.cfg

But the file did not exist in the archive file from your previous post.
Remove that line from the nagios.cfg file and see if that fixes the issue.

Hi Tgriep:

I had already verified that and I still have the same problem. What I do not understand is why I get that null error, and if I commented everything, it gives me the logical error that it is not in my account or host and service.

Code: Select all

root@debianNC:/usr/local/nagios/etc/objects# cat oficina.cfg
define host{
        use generic-networking-device
        host_name FIREWALL
        alias FIREWALL
        address 192.168.6.1
        }

define service{
        use generic-service
        host_name FIREWALL
        service_description Ping
        check_command check_ping!60.0,5%!100.0,10%
        }
root@debianNC:/usr/local/nagios/etc/objects# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
