Hi Dirk, The attribute still exists. However, it is now called "IncludeCallerData". SocketAppender has this attribute while JMS(Queue|Topic)Appender don't (although they should). DBAppender always includes called data, since comparatively computing caller data is much faster than inserting into a DB. Does this help? dirk ooms wrote:

Hello,

In log4j LocationInfo was an attribute of several appenders (e.g. Socket, SMTP) to determine whether the 'expensive' location info should be determined. I couldn't find this attribute anymore in logback, what is logback's approach to this? I understand that for e.g. SMTPAppender this info could be derived from its contained Layout, but what about SocketAppender?
