I've been told that the log4jxmlevent layout doesn't prints nothing about the exception. What layout will help me?

thought I would share. Log levels matter You should think carefully about your log levels as you start adding logging to your app. Trace should probably be used sparingly, because when you turn on log level ‘Trace’ that means you’re pretty much logging EVERYTHING. Log level Debug or Info might be a better level to start with. This makes a bit more sense as you think about the types of things you might be logging in production. If you log very large detailed messages – like complete dumps of email messages with attachments – you might want to log just those few large things using the Trace log methods. That way, when you change the log level to Debug in the nlog.config, you won’t log the gigantic messages to your log. Automatic log rotation Nlog can automatically rotate your logs. It can be configured to keep the last ‘n’ number of days and delete the rest automatically. This can be very useful in production, where you don’t want System Operations to worry about rotating logs or deleting old logs. Here is a sample nlog.config that handles log rotation automatically: Programmatically find where the log is You can use the NLog API to find out where the current log is programatically. This can be useful if you want to email the current log for some reason. To get the current log file, you need to know the current log file name in the nlog.config. // Find the correct target var fileTarget = (FileTarget)LogManager.Configuration.FindTargetByName("f"); // Using the target,
