[veeravamsi]

Hi Team,

I have configured two Servers using Wizard on fresh installation of 5.7 Nagios XI. And Monitors are not reflecting on Status Pages ( Host Summary / Service Group Summary , etc ). When i manually run these from CCM and i GOOD Response.

Anything i could check to find out whats causing this behaviour.

Hi Vamsi,

This is a known issue right now impacting certain systems, however, we are making good progress on correcting this and we should have new maintenance release out soon.

If possible it would best to wait for 5.7.2, otherwise, we can provide steps to revert the backend database utility to the previous version.

Let me know how you would like to proceed. Thanks, Benjamin

Also, it would be helpful to review your system profile as well for any other errors.

To send us your system profile.
Login to the Nagios XI GUI using a web browser.
Click the "Admin" > "System Profile" Menu
Click the "Download Profile" button
Save the profile.zip file and share in a private message or upload it to the post/ticket, and then reply to this post to bring it up in the queue.

Thanks Benjamin. Server where this is running is fresh installation so any quick fix or workaround till i get 5.7.2 ?

HI,

Yes, if it's affecting your monitoring and are unable to wait until 5.7.2, then I would recommend downgrading the backend database daemon to the previous versions ( see instructions below).

Code: Select all

systemctl stop nagios
cd /tmp
rm -rf /tmp/nagiosxi
wget https://assets.nagios.com/downloads/nagiosxi/5/xi-5.6.14.tar.gz
tar zxf xi-5.6.14.tar.gz
cd /tmp/nagiosxi/subcomponents/ndoutils
./install
systemctl enable ndo2db

Then edit your /usr/local/nagios/etc/nagios.cfg and make sure this line is uncommented:

Code: Select all

broker_module=/usr/local/nagios/bin/ndomod.o config_file=/usr/local/nagios/etc/ndomod.cfg

Make sure this line is commented:

Code: Select all

#broker_module=/usr/local/nagios/bin/ndo.so /usr/local/nagios/etc/ndo.cfg

Then start the nagios service:

Code: Select all

systemctl start nagios

Let me know if you have any questions. Benjamin

Hi,

That error message suggests it could not initialize a database connection. Do you have the MySQL service running and have you changed any of the default passwords? Also, is the database offloaded?

Can you PM your system profile, so I can check the ndo and Nagios configuration files. Thanks, Benjamin

Yes we have changed default Password . While i get the system profile , any other steps i can do to update/bypass with changed password ?

Hi,

After further review it looks like the mysql-devel package is missing from the system, and that might be why it cannot compile the old version.

What operating system are you using? And what is the output of the following command ( post the full output to the thread)?

Code: Select all

yum list installed

Lastly, please PM your system profile when you have a chance. Thanks, Benjamin

This is resolved after 5.7.2 upgrade. So you can close this thread. Thank you !
