This patch adds the ability for the Observium (http://www.observium.org/) nginx app monitor to get its data directly from PHP, rather than the standard path via SNMP or via the unix-agent (which doesn't work properly on some operating systems)
For the corresponding nginx config, see http://www.observium.org/wiki/Application/nginx (but make it also accessible to the IP address of your Observium host)
Where do we have save this patch?
