Web log analysis software
Web log analysis software (also called a web log analyzer) is a kind of web analytics software that parses a server log file from a web server, and based on the values contained in the log file, derives indicators about when, how, and by whom a web server is visited. Usually reports are generated from the log files immediately, but the log files can alternatively be parsed to a database and reports generated on demand.
Features supported by log analysis packages may include "hit filters", which use pattern matching to examine selected log data.[citation needed]
