Error: (0) Undefined property: CorePDOHandler::$data

Hi,
do you know what's wrong with this? It happens at random and it goes away after a while. Nagvis says it can't connect to the database.

Centos 7
Nagios XI 5.11.2
PHP 7.4.33
mariadb 5.5

Hi AirBank_HD,

Thanks for reaching out! Looks like someone else had a similar issue here. Seems to be a common CentOS 7/8 issue.

Please edit the following file:

Code: Select all

/usr/local/nagvis/share/server/core/classes/ViewManageRoles.php
Change this line from:

Code: Select all

if (count($name) > AUTH_MAX_ROLENAME_LENGTH)
To this:

Code: Select all

if (strlen($name) > AUTH_MAX_ROLENAME_LENGTH)
Let us know if the issue persist or is resolved...

Thanks!
