Change Nagios' Default Home Page

My last install of Nagios on CentOS went all fine except the home page of Nagios was not loading the main container with welcome page. It was blank. I had to change default home page to something meaningful. I changed it to "tactical overview" page.

In /usr/local/nagios/share/index.php or /usr/share/nagios/htdocs/index.php file, change this line

$corewindow="main.php";

to:

$corewindow="cgi-bin/tac.cgi";

If you do not find your index.php in above two locations, try using this command to locate it on your disc:

locate index.php | grep nagios

Here are a couple of paths that you may be interested in
