Host & Services Not Displaying

[mkeey]

I’ve been trying to add monitors to the new Europe Server Monitoring XI and have had numerous issues. Missing config files, users not setup correctly, and so on.

I’ve fixed all the issues and got one server added from Scott Dick’s list, host-name. It was added and shows up in Config Manager (see attached screen print) but it does not show up in the Home display (see other attached screen print).

I get no errors but it’s not showing up.

I would like verify that you have applied the configuration. Go got Configure > Quick Tools > Apply Configuration. Next, go to the Home > Monitoring > Hosts and serach for host-name by typing the name in the search box.

Let me know if it shows up. If not, did you get any errors when you applied the configuration ( if so please post a screen shot of the errors).

Thanks.

Yes I did the Apply. No I don't get any errors.

Hello @mkeey,

Please try to stop and re-start restart Nagios, and then check again.

Code: Select all

#RHEL 6 | CentOS 6 | Oracle Linux 6 | Ubuntu 14
service nagios stop
killall nagios
service nagios start

#RHEL 7 | CentOS 7 | Oracle Linux 7 | Debian | Ubuntu 16/18
systemctl stop nagios.service
killall nagios
systemctl start nagios.service

Verify that all system components are up and running from the Admin menu page. If it's still not displaying, please send me a copy of your profile, you can download it from Admin > System Profile > Download Profile and send it over in a private message.

Thanks.

Thought it easier to reboot the server. Did that and everything is displaying correctly now. Is there some sort of caching issue with Nagios that shutting down the application will resolve? Memory leak? Bug or something?

Hi @mkeey,

While your we're at it, we should just check your database logs and make sure you don't have any crashed tables causing issues. Run the following from the command line:

Code: Select all

# MySQL
tail -n 20 /var/log/mysqld.log
# MariaDB
tail -n 20 /var/log/mariadb/mariadb.log

Are there any error logs showing crashed database tables?

We are not aware of any memory leaks in the latest version of Nagios Core.
