TCAT-AS-000270 - The first line of request must be logged.
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 "%r" pattern code is included in the pattern element and logs the first line associated with the event, namely the request method, URL path, query string, and protocol ('"' simply specifies a literal double quote). Including the pattern in the log configuration provides useful information about the time of the event which is critical for troubleshooting and forensic investigations.
As a privileged user on the Tomcat server: Edit the $CATALINA_BASE/conf/server.xml file. Modify the <Valve> element(s) nested within the <Host> element(s). Change the AccessLogValve setting to include "%r" in the pattern= statement. EXAMPLE: <Host name='localhost' appBase='webapps' unpackWARs='true' autoDeploy='false'> ... <Valve className='org.apache.catalina.valves.AccessLogValve' directory='logs' prefix='localhost_access_log' suffix='.txt' pattern='%h %l %t %u "%r" %s %b' /> ... </Host> Restart the Tomcat server: sudo systemctl restart tomcat sudo systemctl daemon-reload
