No Hosts/Services/Contacts error

We have Nagios XI 5.6.10 running on RHEL 7 VMs.

When I attempt to apply a new configuration, I get the following error:

Error: There are no services defined!
Error: There are no hosts defined!
Error: There are no contacts defined!

I can view the hosts/services in the DB, and the configuration files for them are on the server.
I can also see the services in the DB.

However, a bunch of the configuration files are blank on the server

Code: Select all

When I look at the snapshot, these same files are blank.

Every time I try deleting the files from the GUI and writing them, they come back blank.
If I try importing them into the DB from a good snapshot through the GUI, it says it completes, then comes back blank when I delete/write or when I try to apply a new configuration.

I have also attempted to restore from a snapshot, but I still can't write any changes.

Any suggestions would be appreciated.


I have run repair_database and it comes back and says no problems found.
I have tried reconfigure_nagios and it comes back warning that no Contacts/Services/Hosts are found, even though I see them in the GUI and in the Database.

To be honest, this is a DEV server, only used to test adding new servers in and make sure all the monitoring works prior to moving them to PRD. If someone could even tell me how to clear everything out and let me start with a blank slate, that would work also.

You can restore the CCM to a default config by running:

Code: Select all

/usr/local/nagiosxi/scripts/restore_defaults.sh

Unfortunately, that didn't work. Everything still shows present.

Hi Henry,

There should be one host when you revert back to the default CCM settings, so something is off here. Are you able to run any configuration wizards?

Can you send the profile over from this server?

Additionally, please run the following command to dump the configuration database and attach this file as well.

Code: Select all

mysqldump -uroot -pnagiosxi nagiosxi > nagiosxi.sql

Hi Henry,

One thing I noticed looking through the profile is that there are a number of logical volumes set up and the nagios volume is showing full. This is where the configurations are stored, and that's likely why it cannot write the changes.

Code: Select all

/dev/mapper/vgdata-lvnagios                   9.8G  9.3G   60K 100% /usr/local/nagios

Thank you! I have cleaned up the drive of the 6GB of perfdata.

However, I still cannot write any changes. It still gives the same error. Even when I revert to a previous working snapshot, it tells me that there are no contacts/hosts/services. I can see them in the GUI, but I am still not able to apply any changes.

I am able to get into the database and run a repair_database and I am told everything works.


I also attempted to import the configuration files from a working snapshot to see if that helped, and it isn't letting me.


At this point, I am going to restore the server to a previous state to try and fix the issue.

Unfortunately, a system restore to a backup also didn't fix the issue.

Ok, I was able to fix the issue doing the following:

Backup another NagiosXI instance
edit the restore_xi.sh script on this box to force it to use the correct offloaded DB instead of the DB from the server I backed up.
Restore the backup onto the corrupted server
Fix the certificate name as listed in the SSL Nagios documentation https://assets.nagios.com/downloads/nag ... s%20XI.pdf
Edit the configuration files as listed in the instructions for offloading the database https://assets.nagios.com/downloads/nag ... Server.pdf
Edit the configuration files as listed in the change default passwords document https://library.nagios.com/library/prod ... passwords/

That seemed to fix everything.
