Web server
Statistics about web pages served by the built-in web server since power-on. Only pages/files fetched from the USB memory are counted - configuration page accesses are not counted.

Users - Number of users served.
Web pages - Number of web pages (.html) served.
Files - Number of files served. Usually there is one file request for the web page itself and one extra for each picture on the web page. Thus one web page access can result in several file accesses.
