Access Log
An access log is a list of all the requests for individual files that people have requested from a Web site. Contents differ depending on the web server, though in each case the log can be analyzed to yield information such as:
-site accessers' IP address and domain name
-date and time of access
-accessed file names
-(in the event the site was accessed via link) the source-link page's URL
-browser and OS information
-download time
-sent and received byte count
-service condition code
-etc.
Every time a site is accessed from a particular server, one line of log data per category (such as those listed above) is added to the corresponding log. Ordinarily site managers do not look at the access log, and analyses of per-category tabulated log entries require a separate log analysis software.
