+How to get this working on Linux/Apache:
+
+Create a new directory /var/www/monitor and copy all files htdocs/* files there.
+
+Include these lines in /etc/apache2/httpdocs
+---
+<Directory /var/www/monitor>
+    Options +ExecCGI
+</Directory>
+AddHandler cgi-script .cgi
+---
+
+Restart Apache: sudo /etc/init.d/apache2 restart
+
+Check that the perl XML-RPC modules is available  ("sudo apt-get install librcp-xml-perl" on Ubuntu)
+
+Edit /var/www/monitor/monitor.cgi to update the IP addresses for the Grid server (TODO: improve this)
+
+Start OpenSim in grid mode, use a browser to open http://localhost/monitor/monitor.cgi
