Nagios Support Forum

Hi
We have an old installation of Nagios 3.0.6 running on Redhat 5 monitoring around 700 servers, and have recently built a new NagiosXI server on Centos 7. Rather then having to set up each server on the new NagiosXI installation is there a way to move the servers and services across ?

https://assets.nagios.com/downloads/nag ... ios-XI.pdf covers migrating from core to XI. Review it and let us know if you have any questions or run into any issues.

Hi

Thanks you for your reply

I have tried this but get an error when I go to apply the changes

Error: Could not find a service matching host name 'XXXX' and description '0' (config file '/usr/local/nagios/etc/serviceextinfo.cfg', starting on line 10264)
Error: Could not expand services specified in extended service info (config file '/usr/local/nagios/etc/serviceextinfo.cfg', starting on line 10264)


/usr/local/nagios/etc/serviceextinfo.cfg does not contain any data so i'm not sure where its getting line 10264 from

more /usr/local/nagios/etc/serviceextinfo.cfg

Any ideas ?

It sounds like there's a service with a config named '0' pointing to a host that doesn't exist. Does the 'XXXX' host exist? Do you see a service with a config name '0' under Configure > Core Config Manager > Monitoring > Services ? If so, edit it to review the config and/or disable it.

Ok I trashed the server and started the import again. This time I'm getting a different issue error.

Apply Configuration
Backend login to the Core Config Manager failed.
An error occurred while attempting to apply your configuration to Nagios Core. Monitoring engine configuration files have been rolled back to their last known good checkpoint.

The show errors box is empty. Having a look on google I saw to look in the /usr/local/nagiosxi/var/cmdsubsys.log log file whilst running the apply configuration is running. Below is the output from this file

Any ideas on this ?

- Importing: /usr/local/nagios/etc/import/extended_service_info_templates.cfg .. ERROR
I would skip trying to import your host/serviceextinfo as it's no longer used.

Remove this file:
Continue repeating the processes (fix, verify, fix, verify) until you have a valid config.

If you need help, go to Configure > Core Config Manager > Tools > Config File Management:
- Click the Delete Files button (don't worry, it's safe, they will be rewritten)
- Then click the Write Configs button
- Once they are done being written (don't do anything in between, don't apply config), run this command and send me the resulting /tmp/NAGIOSBADFILES.zip file:

Thank you

Hi

Thanks you for the response. The advice provided has helped to get the import done. In case anybody else has a similar issue in addition to the file you suggested that I remove, I also removed :-
Thanks for all your help.

Thanks for all your help.

Your welcome. Did you have any other questions or may we close this thread.

There is just one more oddity I have noticed. On all the imported servers, the Linux servers now have nrpe services set up, previously we used check_by_ssh, is there any easy way of removing the nrpe checks an re-enabling the check_by_ssh ?

Thanks

Hello @razah,

Probably, the easiest way is to use the Bulk Modifications tool from the CCM to change the check command on those services. Go to Configure > CCM > Tools > Bulk Modifications Tool.
