I am using NLog and following the recommended pattern of having a log declare on each class, for the purpose of being able to track which class/method has written to the log. I do find this very useful to have a bit of a top level 'stack trace' with each log write.
My code used to look like this:
class SomeClass { private static readonly Logger logger = LogManager.GetCurrentClassLogger(); void DoStuff() { logger.Debug("stuff"); } }
I recently had the requirement my single project to write to 3 separate log files, and to do this, I added multiple loggers and targets as specified here: https://stackoverflow.com/a/21711838/191206
However, now in my log files, I have lost the class level name. It now just writes the log name that I specified in the NLog.config. I've considered simply adding the method name myself with a call to
System.Reflection.MethodBase.GetCurrentMethod(); // use Name property
or using something else in Reflection like this
However, I'm wondering if NLog has something built into this that I'm missing? The Debug() method I only see the ability to write a string, with parameters & optionally formatted..
Is this built into NLog?
The following types can be configured: Targets - the destinations of a logevent, e.g. file, database, console. Layout - the layout e.g. json, csv, plain-text (default) Layout renderers - the template markers, e.g. ${message}, ${exception}, ${date}
Writing Log Messages With NLog The available methods for logging are (in ascending order): Trace, Debug, Info, Warn, Error, and Fatal. Each of these methods creates a log message with a corresponding log level—an indicator of the message's importance.
There is a built in layout renderer called ${callsite}
that you can use to include the call site information (class name, method name and source information) in your log entries:
<targets> <target name="task1File" xsi:type="File" layout="${callsite} - ${message}" fileName="${basedir}../Data/debugLog1.txt" archiveAboveSize ="5000000" maxArchiveFiles="2"/> <target name="task2File" xsi:type="File" layout="${callsite} - ${message}" fileName="${basedir}../Data/debugLog2.txt" archiveAboveSize ="5000000" maxArchiveFiles="2"/> </targets>
