To enable lighttpd status and config pages, you need to edit lighttpd.conf

vi /etc/lighttpd/lighttpd.conf

Find

#                                "mod_status",

Replace with

                                "mod_status",

Find

#### status module
#status.status-url          = "/server-status"
#status.config-url          = "/server-config"

Replace with

#### status module
status.status-url          = "/server-status"
status.config-url          = "/server-config"

Restart lighttpd

/etc/init.d/lighttpd restart

Now you can visit urls like

http://your-ip/server-config

and

http://your-ip/server-status

To view lighttpd status and configuration.
