Nagios XI not working

[ITNO-SGAL]

Hello,

I have Nagios XI 5.8.6 installed.

From today at 9:30 am i cant see anymore nothing on dashboard, or service status.

I only can see nodes at notifications. It looks like something is going wrong with the graphical interface.

Can you suggest me something?

Hello @ITNO-SGAL

Thanks for reaching out, and want to start off by taking a look at running services.

Code: Select all

systemctl status nagios

Code: Select all

systemctl status httpd   #or apache2

Code: Select all

systemctl status mysqld

You can restart the services by substituting 'status' with 'restart' *(example: systemctl restart nagios)

Please send over the System Profile if you find that the issue persists:

Code: Select all

rm -rf /usr/local/nagiosxi/var/components/profile.zip
/usr/local/nagiosxi/scripts/components/getprofile.sh SUPPORT

Then send the resulting /usr/local/nagiosxi/var/components/profile.zip​ file via Private Message.

Thanks,
Perry

Hello again,

All the 3 services are running, i made a restart of them and it is the same thing.

and

The profile.zip is now generated, i am sending you in private message.

Hello @ITNO-SGAL

Thanks for sending over the System Profile, after review we see that on Sun Nov 21 around 08:25:46 things are unable to connect or resolve the host (localhost, hostname). Two examples:

httpd: Could not reliably determine the server's fully qualified domain name....

ndo_handle_host_status(ndo-handlers.c:1036): Unable to bind parameters

Following to check:

• System /var/log/.. Logs
• /etc/hosts file
• Apache configuration updates
• proxy config's
• SELinux Policy
• Firewall Rules
• IPTABLES Rules
• httpd Service Status restart

Please let us know how things look and if you need further assistance.

Thanks,
Perry
