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?
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>
