Hi Thomas, The conversion specifier %h is logback-access specific and unavailable in logback-classic. For the list of conversion words available in logback-classic see https://logback.qos.ch/manual/layouts.html#conversionWord You should place the remote host address in MDC as you did for xForwaredFor.

I am using logback v1.1.3 with my deployed Weblogic application. I am trying to log client ip address along with the xForwaredFor IP address. I added the MDC filter to the application deployment web.xml file and modified the logback.xml file. The log output correctly displays the xForwardedFor IP address. However, I am getting a PARSER_ERROR for the client ip (IP=%h). Any ideas on logging the request source IP?

Thanks
