Nagios Core to Nagios XI Migration - Import Error

[maxiz1987]

Hi Folks,

I am having the following issue that I will describe below and I would appreciate any kind of help that you can bring to me!

Scenario:

- Nagios Core
- New Nagios XI 5 Server

Steps:

I followed the steps from the guides:

https://assets.nagios.com/downloads/nag ... ios-XI.pdf


Issue:

- Most of the services are defined as templates since they are common between many of the servers.
- I have followed the order in which all files should have be imported
- All of the services templates are OK
- However when I import the services from a host that uses services templates, the services are not imported, I only see a service with the file template and it is empty.
- How file looks like after using pre import tool:

Code: Select all

define service{
use                             ping
host_name                       srv_metroweb
check_period                    24x7
contact_groups                  sdi, operadores
_sin_dashboard                  1
_sin_service                    INFO
_sin_environ                    INFR
_sin_group                      SDI
}
define service{
use                             generic-nt-process-java
host_name                       srv_metroweb
check_period                    24x7
contact_groups                  sdi
_sin_dashboard                  1
_sin_service                    INFO
_sin_environ                    INFR
_sin_group                      SDI
}
define service{
use                             generic-nt-service-nds
host_name                       srv_metroweb
check_period                    24x7
contact_groups                  sdi
_sin_dashboard                  1
_sin_service                    INFO
_sin_environ                    INFR
_sin_group                      SDI
}
define service{
use                             generic-nt-service-termsrvc
host_name                       srv_metroweb
check_period                    24x7
contact_groups                  sdi
_sin_dashboard                  1
_sin_service                    INFO
_sin_environ                    INFR
_sin_group                      SDI
}
"srv_metroweb.cfg" 40L, 1340C

I have attached many screen shots in order to provide a guide to it.

I don't understand why this is happening... When I import hosts that don't use service templates but they have the check command defined on its file the import is OK.

Can you post your original config file, before you ran the Prep tool so we can view it?
There may be an invalid character, etc that is stripping the required fields when the prep is run against it.

[lmiltchev]

It seems like the "service_description" directive is missing from these service definition... It is mandatory:
https://assets.nagios.com/downloads/nag ... ml#service

I would recommend running the Write Config Files tool after each of the import steps

commands -> timeperiods -> contacttemplates -> contacts -> contactgroups ->
hosttemplates -> hosts -> hostgroups -> servicetemplates -> services -> servicegroups

just to make sure you don't have any config errors before proceeding further.

What is the error you are getting?

Based on the information provided it looks like it's doing it properly, let's use this as an example:

Code: Select all

define service{
use                             ping
host_name                       srv_metroweb
check_period                    24x7
contact_groups                  sdi, operadores
_sin_dashboard                  1
_sin_service                    INFO
_sin_environ                    INFR
_sin_group                      SDI
}

When you import that it will create a service with:
- A blank service description
- The ping service template selected under Manage Templates
- The check_period defined under the Check Settings tab
- The contactgroup defined under the Alert Settings Tab > Manage Contactgroups
- Your _variables in the Misc Settings tab > Manage Variable Definitions

Is that not doing that for you or am I missing something?

Thank you

Hi ssax! Thanks for answering on my post!

As you said when I import it it does the following:

- A blank service description
- The ping service template selected under Manage Templates
- The check_period defined under the Check Settings tab
- The contactgroup defined under the Alert Settings Tab > Manage Contactgroups
- Your _variables in the Misc Settings tab > Manage Variable Definitions

However, I see the ping service templated selected under manage templates but it doesn't load the information from the template.

I would expect that it loads the config name, the check command, the arguments of the commands, etc

Do I explain myself? I just see on manage template the service template but I don't see that this loads the information from the service template.

Hi lmiltchev!

I would expect that the service description were loaded from the command template as in this way works on Nagios Core. Doesn't it works on the same way on Nagios XI?

When you apply configuration it should show the template information on the service, it won't add it to the service definition in Configure > Core Config Manager > Services when importing, it only will apply it at run-time.

Please look at the service definition after applying configuration in /usr/local/nagios/var/objects.cache and you should see them defined.

[maxiz1987]

I have figured out what it is.

service_description is a mandatory field and the service does not inherit it from the template - so if you don't add it, the import tool load an empty service.
