Description
The access logfile format is defined within a Valve that implements the org.apache.catalina.valves.AccessLogValve interface within the /opt/tomcat/server.xml configuration file: The %t pattern code is included in the pattern element and logs the date and time of the event. Including the date pattern in the log configuration provides useful information about the time of the event which is critical for troubleshooting and forensic investigations.
