Click on the blue Hosts box:

Do you see the hosts you want to remove there? If so click the red X under
actions.
WARNING: This will remove them and their related items (services)
entirely and permanently.
If you don't see the hosts there then please provide a system profile:
To send us your system profile.

2. Click the "Admin" > "System Profile" Menu
3. Click the "Download Profile" button

Thanks

Hi,
I see 90 hosts and 295 hostgroups when I look at the Core Configuration Manager.
Does that sound like what you are expecting to see?
Thanks

Hi,
On the Nagios XI server please do the following:
Code: Select all
mysql -u root -pnagiosxi nagios
select count(*) from nagios_hosts;
select count(*) from nagios_hosts
where display_name like '';
And let me know what the results are for the two select count(*) commands.
In the second command this: '';
is <single-quote><single-quote><semi-colon>
Thanks

Hi
Go to the Core Config Manager
Tools > Config File Management
Click on Write Configs and Verify Files to check for config errors
If you don't have any errors, click on Delete to remove all host and service configuration files.
Next, apply configuration. The configs will be recreated with whatever is in the database.
Let me know if that solves it.
Thanks
