Problem with import Nagios Core to NagiosQL

[Vihsalles]

Good morning guys.

I'm having some problems with NAGIOSQL for monitoring printers and computers.

I have installed and configured NAGIOS CORE but it is very complicated to manage, especially changing printers that change IP, serial number, etc., so I decided to install NAGIOSQL to help me with this task, after learning a little I managed to get the interface working However, now I'm having some problems that I'll report below:

When trying to import any configuration from NAGIOS CORE the screen crashes and the file is not imported into NAGIOSQL (PHOTO1)

In the Administrations --> Support menu, the following errors appear, which I honestly don't know if is "normal" (PHOTO2)

In the Tools--> Nagios Control menu, the Check configuration files buttons give the following error (PHOTO3)

on the Restart Nagios button another error (PHOTO4).

If anyone can help me in these cases I would be immensely grateful.

Good afternoon everyone, an update, of the 4 items with problems I managed to solve 3, which were basically a configuration of directories in administration --> Config Targets --> Modify.

However, I still have the main problem of not being able to import the files from Nagios Core to NagiosQL , could this be due to the read/write problem in settings.php

I managed to enable the configuration, I discovered that NagiosQL is in opt/nagiosql

However, I have a problem when trying to import the Nagios Core files, the problem remains, I can't import them, when the attempt is made the screen crashes and unfortunately it doesn't generate any error log, can anyone help me?
