How can I configure logging levels in ASP.NET MVC using NLog?

To configure logging levels in ASP.NET MVC using NLog, you need to set up the NLog.config file. You can define different logging levels like Trace, Debug, Info, Warn, Error, and Fatal.

Can you show me an example of the NLog.config file?

Sure! Here's a simple example:

<nlog>
  <targets>
    <target name="logfile" xsi:type="File" fileName="logs/app.log" />
  </targets>
  <rules>
    <logger name="*" minlevel="Debug" writeTo="logfile" />
  </rules>
</nlog>

What if I want to log only errors?

You can change the minlevel attribute in the rules section to Error like this:

<logger name="*" minlevel="Error" writeTo="logfile" />

Is it possible to log to multiple targets?

Yes, you can define multiple targets in the <targets> section and specify them in the <rules> section. For example, you can log to both a file and the console.
