Folks, I did a fresh nagios 3.0.6 installation on a linux server. Things look okay - No serious problems were detected during the pre-flight check [root@DELL8B81Y11 sbin]# service nagios restart Running configuration check...done. Stopping nagios: /etc/init.d/nagios: line 67: kill: (24483) - No such process done. Starting nagios: done. [root@DELL8B81Y11 sbin]# service nagios status nagios is not running [root@DELL8B81Y11 sbin]# Why am i getting like this. I have a nagios.conf file in /etc/httpd/conf/nagios.conf and the content is ScriptAlias /nagios/cgi-bin/ /usr/local/nagios/sbin/ <Directory ?/usr/local/nagios/sbin/?> AllowOverride AuthConfig Options ExecCGI Allow from all Order allow,deny </Directory> Alias /nagios/ /usr/local/nagios/share/ <Directory ?/usr/local/nagios/share?> Options None AllowOverride AuthConfig Order allow,deny Allow from all </Directory> At the webinterface when i type <a href="http://localhost/nagios/">http://localhost/nagios/</a> i get to see the webinterface but when i click host detail i see this : <pre><!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>500 Internal Server Error</title> </head><body> <h1>Internal Server Error</h1> The server encountered an internal error or misconfiguration and was unable to complete your request.
