Nagios apply configuration issue

Post by mejokj »

Hi,

We are facing a isssue with the nagios apply configuration.

+++++++++++++++++
Error: Service description missing from list '' (config file '/usr/local/nagios/etc/servicegroups.cfg', starting at line 117)
Error: Could not expand members specified in servicegroup 'UPS - Temp' (config file '/usr/local/nagios/etc/servicegroups.cfg', starting at line 117)
++++++++++++++++++

After we activate the the service name "Internal Temp" of host example.com the issue will be fixed. But the again after some time the service will be disabled automatically and apply configuration failed. This service is parent service under the service there are 28 managed hosts . Why this service Internal Temp is automatically removed.

Hi,

After you activate the service again and it's working, are you making any new configuration changes and are using any type of automation to make those changes?

Try to run through the following steps in Configure > CCM > Tools > Config File Management to clear the error.

1. Delete Files
2. Write Files
3. Verify Files ( if you see any errors follow the message to correct and repeat steps 1-3 until it passes)
4. Restart Nagios Core

Hi Benjaminsmith,

Yes, we have tried removing a few hosts after activating the service and not using any automation to do any changes.

Note: The service gets failed even if we did not do any configuration changes.

Kindly confirm if we perform the above steps, will it remove any data/graph already existing in Nagiosxi?

Thanks

No, this is a safe procedure, it won't affect existing or future performance graphs.

Let me know if you're able to resolve the issue.

Thanks,

Hi,

So the the logs look ok in the profile but I noticed that the database is offloaded in this instance so that was not included. Can you retrieve this from the offload server (db)?

Code: Select all

/var/log/mariadb/mariadb.log
/var/log/mysqld.log
Also, I can test your configurations here with a database dump. If could post the following file, that would be very helpful. Thank you, Benjamin

Code: Select all

mysqldump -uroot -pnagiosxi nagiosxi > nagiosxi.sql

Hi,

I imported your configurations and have been able to apply configuration. I'm able to view the service group UPS - Temp (with 28 services).

However, I did notice some database issues.

Code: Select all

181118 11:45:13 [ERROR] mysqld: Table './nagios/nagios_notifications' is marked as crashed and last (automatic?) repair failed
181118 11:45:13 [ERROR] mysqld: Table './nagios/nagios_notifications' is marked as crashed and last (automatic?) repair failed
181118 11:45:13 [ERROR] mysqld: Table './nagios/nagios_notifications' is marked as crashed and last (automatic?) repair failed
Please log in as root and run the following repair script.

Code: Select all

/usr/local/nagiosxi/scripts/repair_databases.sh
Then try to repeat the steps in Config File management and let me know the results. If it's still failing try to correct the error based on the message. If that's unsuccessful, please dump the nagiosql database and send it over.

Code: Select all

 mysqldump -uroot -pnagiosxi nagiosql > nagiosql.sql
Thank you,
Benjamin
