title: How can I configure log4j to not print the exception stacktrace?
body: <p>We use Log4j (and Commons Logging) to log our error messages. Now we want to set up an additional log appender that outputs fatal errors to syslog, but without the exceptionally long Java stacktraces (those will still be available in the full log file).</p>
  
  <p>How would one configure this (using log4j.xml)? Is there a filter available to ignore the stack traces?</p>
