tomcat access log 남기기
2022-02-18
아래와 같은 설정을 보고, pattern 에 사용된 것들이 어떻게 세팅될지 궁금해하고있었는데…
<Host name="localhost" ...>
<Valve
className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="localhost_access_log" suffix=".txt"
pattern='%{X-MY-NAME}i %t "%A" "%{PARAM-YOUR-NAME}r" "%r" "%s" "%T" %b "%{User-Agent}i" "%{Referer}i"' />
</Host>
이렇게 쉬운거였다니..
- %a - Remote IP address
- %A - Local IP address
- %b - Bytes sent, excluding HTTP headers, or ‘-‘ if zero
- %B - Bytes sent, excluding HTTP headers
- %h - Remote host name (or IP address if enableLookups for the connector is false)
- %H - Request protocol
- %l - Remote logical username from identd (always returns ‘-‘)
- %m - Request method (GET, POST, etc.)
- %p - Local port on which this request was received. See also %{xxx}p below.
- %q - Query string (prepended with a ‘?’ if it exists)
- %r - First line of the request (method and request URI)
- %s - HTTP status code of the response
- %S - User session ID
- %t - Date and time, in Common Log Format
- %u - Remote user that was authenticated (if any), else ‘-‘
- %U - Requested URL path
- %v - Local server name
- %D - Time taken to process the request in millis. Note: In httpd %D is microseconds. Behaviour will be aligned to httpd in Tomcat 10 onwards.
- %T - Time taken to process the request, in seconds. Note: This value has millisecond resolution whereas in httpd it has second resolution. Behaviour * will be align to httpd in Tomcat 10 onwards.
- %F - Time taken to commit the response, in millis
-
%I - Current request thread name (can compare later with stacktraces)
- %{xxx}i write value of incoming header with name xxx
- %{xxx}o write value of outgoing header with name xxx
- %{xxx}c write value of cookie with name xxx
- %{xxx}r write value of ServletRequest attribute with name xxx
- %{xxx}s write value of HttpSession attribute with name xxx
- %{xxx}p write local (server) port (xxx==local) or remote (client) port (xxx=remote)
- %{xxx}t write timestamp at the end of the request formatted using the enhanced SimpleDateFormat pattern xxx
