Hi,

Is this happening for a single host or service object or is this happening for everything? Please re-produce the error in the user interface, and then immediately download a system profile and send it over in a PM. This will capture any errors in the Apache logs.

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

Additionally, are you seeing any errors on the front end? Open the developer tools in the browsers, and then re-load the page and let me know if you are getting any HTTP error codes.

Hi,

Thank you for the system profile. Is this happening for a single host or service object or is this happening for everything?

Please check the settings and make sure the default backend is set to nagiosxi. Based on the log messages, it's not able to set up a backend connection.

Also, if that's not the issue, please share the following files.

Code: Select all

/usr/local/nagvis/etc/nagvis.ini.php
/etc/httpd/conf.d/nagvis.conf

And the output to the following command. Thanks, Benajmin

Code: Select all

ls -l /usr/local/nagvis/share/server/core/classes/

[trenz.sands.cz]

it is happening for all objects, needed files included in PM.

Hi,

Thank you for those files. We noticed a number of differences between the stock nagvis.ini.php, and the current file.

And seeing these connection errors in the Apache logs.

PHP Fatal error: Declaration of GlobalBackendmerlinmy::__construct() must be compatible with GlobalBackendInterface::__construct($backendId) in /usr/local/nagvis/share/server/core/classes/GlobalBackendmerlinmy.php on line 3

Please make sure the backend settings are set for nagisoxi. You may have to create this if it's not there.

If that doesn't not work, please try removing the following entry from /usr/local/nagvis/etc/nagvis.ini.php.

Code: Select all

backend_merlinmy_1

If that fails, please make a backup of that file and restore the default. Thanks, Benjamin

[trenz.sands.cz]

I have tried backend nagiosxi - there was missing dbhost
I have defined all backend variables from old nagiosxi - same issue
I have created ndomy backend from old nagiosxi - same issue

I have tried defaut file you have posted - it didnt worked

[benjaminsmith]

Hi,

Alright thanks for trying that out, it looks like the issue goes a little deeper than the backend connection.

Let's get an archive of the NagVis install, please send in the /tmp/nagvis.tgz file.

Code: Select all

tar cvfz /tmp/nagvis.tgz /usr/local/nagvis/*

We suspect there is probably is a mismatch between the Object ID's or the names.

Benjamin

I have attached the file in PM - 7.1 MiB
