<span class="diffcontext">In logback 1.0.4 Syslogappender got the <StackTracePattern> property, which we have been using to pass stacktraces to our logserver with a custom prefix for each line.<br><br>This has worked, but we've had a few problems that I finally had some time to look into. My goal has been to achieve a logging behaviour similar to what RollingFileAppender produces.<br><br>I've identified a type of line that does not get sent to syslog. When a stacktrace is logged, RollingFileAppender will log:<br>-the log line<br>-a special line containing IThrowableProxy.getClassName() + IThrowableProxy.getMessage()<br>-the lines of the stacktrace<br>if it is a nested stacktrace, RollingFileAppender will then proceed to log:<br>-a special line containing "Caused by: "+IThrowableProxy.getClassName() + IThrowableProxy.getMessage()<br>-the lines of the nested stacktrace<br><br>Here is an example of a stacktrace produced by RollingFileAppender:<br><br>18.09.2012 18:36:19.312 [INFO] [n.v.w.t.WSTesterServlet] [XXXXIMB.1347986179274.0]: SystemException caused by nullpointer:<br>no.vps.exceptions.SystemException: COM_INVALID_CHAR<br> at no.vps.ws.tester.WSTesterServlet.handleRequest(WSTesterServlet.java:79) [classes/:na]<br> at no.vps.ws.tester.WSTesterServlet.doGet(WSTesterServlet.java:54) [classes/:na]<br> at javax.servlet.http.HttpServlet.service(HttpServlet.java:718) [javax.j2ee.servlet.jar:na]<br> at javax.servlet.http.HttpServlet.service(HttpServlet.java:831) [javax.j2ee.servlet.jar:na]<br> at com.ibm.ws.webcontainer.servlet.ServletWrapper.service(ServletWrapper.java:1657) [com.ibm.ws.webcontainer.jar:na]<br> at com.ibm.ws.webcontainer.servlet.ServletWrapper.service(ServletWrapper.java:1597) [com.ibm.ws.webcontainer.jar:na]<br> at com.ibm.ws.webcontainer.filter.WebAppFilterChain.doFilter(WebAppFilterChain.java:131)</span>
