'''[[Web log]] analysis software''' (also called a '''web log analyzer''') is a kind of [[web analytics]] software that parses a [[Server log|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. Reports are usually generated immediately, but data extracted from the log files can alternatively be stored in a database, allowing various reports to be generated on demand.
Features supported by log analysis packages may include "hit filters", which use pattern matching to examine selected log data.{{Citation needed|date=October 2010}}
