New Install of Nagios XI 2026R1.4 missing hosts

[matson-itops]

Brand new install, I added 3 hosts in CCM . but host status still showing zero hosts
what am I missing?

[matson-itops]

update : service checks work fine, but no hosts and no services show up.

Dumb question but did you apply the changes in ccm?

[laurajames9010]

From my experience, this usually happens if you haven’t applied the configuration yet in CCM, so try clicking Apply Configuration and restarting Nagios to update the host status. basketball stars

yes. several times with several attemps.
applied config is good, I get alerts, etc. just do NOT see it in "host status" or " service status"

Fresh installs of Nagios XI should have localhost as a host already configured. Are you saying you don't see this? This makes me think you likely have a database error. In /usr/local/nagiosxi/scripts, there will be a repair_databases.sh script that you can run that usually fixes issues like these. Repairing the Nagios XI 2024 Databases

Since you're on a new install, if this doesn't solve your problem, I'd recommend starting over as something likely went wrong during the installation process.

thanks for the suggestion. no errors during install.

Looks like ndo3 is required, but it was not installed on a fresh box along
with nagiosXI

is it required? ndo2 is not there either.

NDO3 is required, it is surprising it was not installed. We don't ship NDO2 these days.

Do you have access to install.log? In any case, NDO3 in a NEB module, it should have compiled and loaded when the monitoring engine started.

What version of XI are you coming from?

Hi matson-itops,

Could you show us the broker line from your nagios.cfg ?

Code: Select all

grep "^broker" /usr/local/nagios/etc/nagios.cfg 

And confirm the status of nagios core:

Code: Select all

systemctl status nagios   

Do you see a change in the interface after running the following ?

Code: Select all

/usr/local/nagiosxi/scripts/reconfigure_nagios.sh 

Thanks and best regards
