Two host_name directives in one service definition

I'm trying to remove a single host (host4.school.edu in the snippet below) from a service that's applied to a host group that host is a member of. In CCM, I navigated to the Service Management page for the service, clicked on "Manage Hosts", and added host4.school.edu with the "!" box checked.
When the config is generated, the host is in the service definition as a negation but there's a second host_name line further down that is overriding it. The three excluded hosts in the second host_name line shown below are not listed in the "Manage Hosts" window where I added host4, but clearly they're defined as exclusions
somewhere. Where else in CCM should I be looking?
Code: Select all
define service {
host_name !host4.school.edu
service_description Drive Space - /boot
use service-server-standard
hostgroup_name linux-server-critical,linux-server-standard,nac-appliance-standard
servicegroups linux-server-standard
check_command check_snmp_disk!/boot!-C $USER23$!!!!!!
host_name !host1.school.edu,!host2.school.edu,!host3.school.edu
register 1
}
The server is running RHEL 6.9 64 bit with a manual install of NXI 5.7.1 and no special configurations to speak of.

You may want to start by upgrading to
5.7.2.
Code: Select all
cd /tmp
rm -rf nagiosxi xi*.tar.gz
wget http://assets.nagios.com/downloads/nagiosxi/xi-latest.tar.gz
tar xzf xi-latest.tar.gz
cd nagiosxi
./upgrade
There was a recent issue in
5.7.1 with hosts being duplicated instead of renamed.
Fixed NDO issue where renaming hosts and services with uppercase/lowercase letters caused inconsistencies

If, for some reason, you can't see what's causing this in the GUI, you may want to look at the configuration files directly in the following directory location.

I have upgraded to 5.7.2 and still have the same problem. The config snippet from my original post is from one of the files in /usr/local/nagios/etc/. It is still being generated with two separate host_name lines, causing the first to be ignored and overridden by the second.

You may want to try repairing the database. Please run these two scripts. Best to have a backup just in case!
Code: Select all
/usr/local/nagiosxi/scripts/backup_xi.sh
/usr/local/nagiosxi/scripts/repair_databases.sh
Have you already tried rewriting the configuration files with the
Config File Management tool in the
Core Config Manager?

I have run the database repair and regenerated the config file. It still generates the same way, with two host_name declarations:
Code: Select all
define service {
host_name !host4.school.edu
service_description Drive Space - /boot
use service-server-standard
hostgroup_name linux-server-critical,linux-server-standard,nac-appliance-standard
servicegroups linux-server-standard
check_command check_snmp_disk!/boot!-C $USER23$!!!!!!
host_name !host1.school.edu,!host2.school.edu,!host3.school.edu
register 1
}

Do you have a free variable that holds the following values by any chance?
Code: Select all
!host1.school.edu,!host2.school.edu,!host3.school.edu
Navigate to the
Configure section of
XI using the top bar > click
Core Config Manager under
Advanced Configuration on the left pane > click on the name of the problematic service > select the
Misc Settings tab > click on the
Manage Free Variables button > and make sure there isn't a host_name free variable. That could be where that is coming from.

Yes. Yes we did. Removing that free variable and adding those hosts via the host selection window took care of the problem.
Thank you!
