If you have a lot of dashboards defined, there is a table in the MYSQL database that may not be large enough to store all of them so that could be the issue.
To increase that table, login as root to the Nagios server and run the following command

Code: Select all

echo "alter table xi_usermeta modify keyvalue LONGTEXT;" | mysql -uroot -pnagiosxi nagiosxi

Restart the processes by running to the changes will take effect.

Code: Select all

service nagios stop
service ndo2db stop
service httpd restart
service ndo2db start
service nagios start

Try that and let us know if it fixes the issue for you.

MariaDB [nagiosxi]> alter table xi_usermeta modify keyvalue LONGTEXT;
Query OK, 0 rows affected (0.01 sec)
Records: 0 Duplicates: 0 Warnings: 0

Nothing changed.

Try changing the owner / group of those files by running the following.

Code: Select all

chown nagios.nagios  /usr/local/nagiosxi/html/dashboards/*

Then restart the nagios and apache process by running this

Code: Select all

service nagios restart
service httpd restart

If you still cannot create a dashboard, run the following command
t

Code: Select all

ail -f /var/log/httpd/*_log

Then try and create a dashboard and post the output of the tail command.
Hopefully it will show the error you are experiencing.

It could be a missing SSL setting on the XI server when the system was setup to be accessed over SSL.
Take a look at this link and verify that the system is setup correctly for SSL.

If you are still having issues, please post the following files

Code: Select all

/etc/httpd/conf.d/nagiosxi.conf
/etc/httpd/conf.d/ssl.conf
/etc/httpd/conf/httpd.conf

Then run the following as root and attach the /tmp/info.txt file to this post.

Code: Select all

ls -lR /usr/local/nagiosxi/html/ >/tmp/info.txt
grep use_https config.inc.php >>/tmp/info.txt

In the /etc/httpd/conf.d/nagiosxi.conf file, the section below has to be removed as it is a duplication if the settings in the top of the file and that section is causing the access issues.
Remove this section

Code: Select all

    <Directory "/usr/local/nagiosxi/html">
       AllowOverride All
       Require all granted
    </Directory>

Then restart the Apache daemon by running

Code: Select all

service httpd restart

Then login to the XI GUI and see if you can edit / create dashboards now.

Hello,

I still have the same problem. all users got it. and so impossible to edit dashboards.

Try resetting the owner / permissions for the dashboards folder by running the following as root on the XI server.

Code: Select all

chown -R nagios.nagios  /usr/local/nagiosxi/html/dashboards
chmod -R 777 /usr/local/nagiosxi/html/dashboards
service httpd restart

Then try creating a dashboard, you you get any errors, look in the /var/log/httpd/ log files for any errors and post them here.
