Hello support team,

Since a recent NagiosXI update, none of our Nagvis maps works.
Here is the error message:

Error: (0) json_encode(): Invalid UTF-8 sequence in argument
URL: /nagvis/server/core/ajax_handler.php?mod=Map&act=getMapObjects&show=GTLD&header_menu=1&hover_menu=1&context_menu=1&zoom=100&_ajaxid=1601368696
File: /usr/local/nagvis/share/server/core/classes/NagVisMap.php
Line: 116

#5 /usr/local/nagvis/share/server/core/ajax_handler.php(59): require('/usr/local/nagv...')

Do you have a lead to help us?

Hi,

Let's add the following option to the database configuration file. Edit the /etc/my.cnf and under the [mysqld] section add this line:

Code: Select all

init-connect='SET NAMES utf8'

Then restart the services and let me know if the issue is resolved.If not, what operating system are you currently using with Nagios XI.

Code: Select all

systemctl stop nagios
systemctl restart mariadb
systemctl start nagios

Regards,
Benjamin
