Network Topology

Problem:
From Dashboard-Network Topology-click on any nodes and getting this error “It appears as though you do not have permission to view information for any of the services you requested…
If you believe this is an error, check the HTTP server authentication requirements for accessing this CGI
and check the authorization options in your CGI configuration file.”
Solution:
Edit /omd/sites/xxx/etc/nagios/cgi.cfg, look for below variable and change to * (all authenticated users)
authorized_for_system_information=*
authorized_for_configuration_information=*
authorized_for_system_commands=*
authorized_for_all_services=*
authorized_for_all_hosts=*
authorized_for_all_service_commands=*
authorized_for_all_host_commands=*

Then restart apache
