[ http://jira.qos.ch/browse/LBCLASSIC-185?page=com.atlassian.jira.plugin.syste... ] Ceki Gulcu commented on LBCLASSIC-185: -------------------------------------- Useful stuff. Personally, I would also add the client's host name as well as the "X-Forwarded-For" field found in the http header. More generally though, the complete set of fields as defined in logback-access' PatternLayout would be of interest. See "Logback access" in [1]. The important point is that the fields you have defined, e.g. context path, user name etc. are highly useful for various purposes. BTW, since this is a relatively significant contribution, I would appreciate if you could sign the Contributor License Agreement [2[.

Servlet filter which puts servlet-specific data into MDC --------------------------------------------------------
Key: LBCLASSIC-185 URL: http://jira.qos.ch/browse/LBCLASSIC-185 Project: logback-classic Issue Type: New Feature Components: Other Affects Versions: 0.9.18 Reporter: Torsten Juergeleit Assignee: Logback dev list Attachments: logback-test.xml, RequestLogFilter.java, RequestLogFilterTest.java
Attached you can find a servlet filter which implements a strategy to put servlet-specific data into the SL4F MDC using the following keys: * {{slf4j.servlet.requestId}} - Unique ID of the single HTTP request handled by this filter * {{slf4j.servlet.sessionId}} - ID of the HTTP session this HTTP request is associated with or "" if no HTTP session was created yet * {{slf4j.servlet.contextPath}} - Web apps context path * {{slf4j.servlet.userName}} - Name of authenticated user or "" if no user is authenticated This data is removed after the request is processed. The following configuration parameters are supported by this filter: * {{maxSessionIdLength}} - limiting the HTTP session id length to a certain value, e.g. for WebLogic this could be 52 (default: -1 [unlimited]) To use this filter add the following lines to the {{web.xml file}}: <code> <filter> <filter-name>RequestLogFilter</filter-name> <filter-class>ch.qos.logback.classic.RequestLogFilter</filter-class> <init-param> <param-name>maxSessionIdLength</param-name> <param-value>52</param-value> </init-param> </filter><br> : <filter-mapping> <filter-name>RequestLogFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <code> An SLF4 Logger named {{ch.qos.logback.classic.RequestLogFilter}} is used to log the start end end of calling the filter chain. This information should go into a separate log file.
