Configured server not displayed in web interface

[MxR57]

Greetings,

This is my first time in forum and posting a question, so I apologies in advance if I am not following the forum protocols for posting questions.

Using Nagios Core 4.4.6, once a day we rebuild server_hosts.cfg that includes all the existing operational/active servers. We also rebuild server_hostgroups.cfg based on the properties of the servers in server_hosts.cfg. Finally, we restart Nagios that will use the newly build config files. However, when we bring up the web api, 8 of the newly configured servers are not displayed. They are in both server_hosts.cfg and server_hostgroups.cfg files.

Thanks in advance for helping me solve this.

Hello MxR57,

Can you run

Code: Select all

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

to see if Nagios Core thinks your configuration is good?

You can also check the permissions of your configuration file with ls -l and check /var/log/nagios/nagios.log to see if Nagios Core is running into any errors. It may also contain other diagnostic information that could help.

Thanks for your reply. Here is verifying the nagios.cfg:

sh-4.2$ /usr/sbin/nagios -v /etc/nagios/nagios.cfg

I am not sure what you mean about Nagios running! From GUI API I have:

and I see all the servers in the GUI except the new ones that were added.
