title: Most useful NLog configurations
body: <p>What are the best or most useful configurations for logging with NLog? (These can be simple or complex, as long as they're useful.) </p>
  
  <p>I'm thinking of examples like automatically rolling over log files at a certain size, changing the layout (log message) whether or not there is an exception, escalating the log level once an error has occurred, etc.</p>
