An access log features a record of all of the files which have been requested by the visitors while browsing your Internet site. The list is thorough, so if you have a web page with two embedded images, for example, all of the three files shall be in the log, not only the page. An access log usually includes the date, the OS, the Internet browser and the IP address for each and every file in human-readable form, so you can get an idea about the hottest files on your Internet site. The log, that's also often called "raw data", is an addition to the web data you typically get with a hosting account, not a substitute. An illustration why you may require this type of a log is if you want to use some software on your computer system to prepare a report about the website’s overall performance, but you do not want to use the conventional graphs and tables which come with the server-generated web stats.
