This is a small hack that will show all hostgroups in a 'treewiev' in the left frame in Nagios web-interface. Installation instructions: 1 Unpack the tarfile in a temp-directory 2 Copy grouplist.cgi to Nagios cgi-bin directory (Usually /usr/local/nagios/sbin) 3 Check that the web-server have permissions to run the script 4 Verify the path to your Nagios-installation at the beginning of the script 5 Make backups of index.html in Nagios html-directory (/usr/local/nagios/share) 6 Copy side1.html, side2.html and index.html to the html-directory 7 Reload Nagios in your web-browser 8 Done /Fredrik Wanglund, fredrik.wanglund@datavis.se
