An access log features a record of all the files that have been requested by the visitors while exploring your Internet site. The list is comprehensive, so in case you have a webpage with two embedded images, for example, all of the three files shall be in the log, not only the page. An access log normally includes the date, the Operating System, the Internet browser and the IP address for every single file in human-readable form, so you can get a good idea about the most well liked files on your website. The log, which is also frequently referred to as "raw data", is an addition to the web data you commonly get with a hosting account, not a replacement. A good example why you could need this type of a log is if you intend to use some software on your PC to prepare a report about the website’s efficiency, but you do not want to use the conventional graphs and tables that come with the server-generated website statistics.
