NLog for asp.net core is not filtering Microsoft logs

I have the following nlog.config file in ASP.NET Core 2.1 project. However, it's logging messages from every logger (including Microsoft logger) to console.

<?xml version="1.0" encoding="utf-8" ?>

<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"

      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

      autoReload="true"

      internalLogLevel="Error"

      internalLogFile="${specialfolder:folder=UserProfile}nloginternal-nlog.txt">



  <variable name="fullLayout" value="${shortdate}  [${uppercase:${level}}]  ${logger}: ${message}  ${exception:format=tostring}  url: ${aspnet-request-url}" />



  <!-- enable asp.net core layout renderers -->

  <extensions>

    <add assembly="NLog.Web.AspNetCore"/>

  </extensions>



  <!-- the targets to write to -->

  <targets>

    <!-- write to console -->

    <target name="console" xsi:type="ColoredConsole" layout="${fullLayout}" />



    <!-- write to file -->

    <target xsi:type="File"

            name="allfile"

            fileName="${defaultDirectory}/test-api-all.log"

            archiveEvery="Day"

            archiveFileName="${defaultDirectory}/test-api-all-${#}.log"

            archiveNumbering="Date"

            archiveDateFormat="yyyy-MM-dd"

            maxArchiveFiles="5"

            layout="${fullLayout}" />



    <!-- another file log, only own logs. Uses some ASP.NET core renderers -->

    <target xsi:type="File"

            name="ownFile-web"

            fileName="${defaultDirectory}/test-api-app.log"

            archiveEvery="Day"

            archiveFileName="${defaultDirectory}/test-api-app-${#}.log"

            archiveNumbering="Date"

            archiveDateFormat="yyyy-MM-dd"

            maxArchiveFiles="5"

            layout="${fullLayout}" />

  </targets>



  <!-- rules to map from logger name to target -->

  <rules>

    <!--All logs, including from Microsoft-->

    <logger name="*" minlevel="Trace" writeTo="console" />



    <!--Skip non-critical Microsoft logs and so log only own logs-->

    <logger name="Microsoft.*" maxLevel="Info" final="true" />

    <logger name="*" minlevel="Trace" writeTo="ownFile-web" />

  </rules>

</nlog>

I do not have any logging settings in appsettings.json files. All logger configuration in in nlog.config. In the Program.cs, I'm registering NLog like:

public static IWebHost BuildWebHost(string args) =>

            WebHost.CreateDefaultBuilder(args)

                .UseStartup<Startup>()

                .ConfigureLogging(logging => logging.ClearProviders())

                .UseNLog()

                .Build();

How can I filter out Microsoft logs?

EDIT:

Above configuration started working without a problem the next day without me making any changes :O

Maybe this will work:

  <!-- rules to map from logger name to target -->

  <rules>

    <!--Skip non-critical Microsoft logs and so log only own logs-->

    <logger name="Microsoft.*" maxLevel="Info" final="true" />



    <logger name="*" minlevel="Trace" writeTo="console" />



    <logger name="*" minlevel="Trace" writeTo="ownFile-web" />

  </rules>

The order of the logging rules are important, as the rules are matched from the top. See also https://github.com/NLog/NLog/wiki/Configuration-file#rules

The order of your logging rules seems to be correct. I suggest trying to double check if your updated nlog.config file is being copied to the build directory (e.g. binDebugnetcoreapp2.1nlog.config)

I kind of encountered the same issue, but found out that debugging using Visual Studio, it sometimes doesn't really copy the nlog.config file to your build directory. So the solution is to Clean the project first, then Build, and finally Debug.

Maybe this will work:

  <!-- rules to map from logger name to target -->

  <rules>

    <!--Skip non-critical Microsoft logs and so log only own logs-->

    <logger name="Microsoft.*" maxLevel="Info" final="true" />



    <logger name="*" minlevel="Trace" writeTo="console" />



    <logger name="*" minlevel="Trace" writeTo="ownFile-web" />

  </rules>
