I installed a fresh copy of Nagios XI but the web transaction didn’t work very well. I made some changes to fix the problems
The first status information error I had was: (null)
To fix this I installed perl-suidperl
yum install perl-suidperl
After that I get I new error: Return code of 255 is out of bounds
To fix this I changed the permissions of the webinject folder and its files:
chown nagios:nagios /usr/local/nagiosxi/etc/components/webinject/ chown nagios:nagios /usr/local/nagiosxi/etc/components/webinject/*
Did was the trick.
