I’m trying to log only Errors into the Windows syslog (events viewer), I tried many solutions but none of them run as expected. I still see warning messages in the Windows syslog.

It’s an Asp.Net Core project (nuget 2.2.0) with NLog 5.2.8.
I don’t have any a content related to log configuration in my appsettings.json file and here is the content of my nglog.config file.

What am I missing?

<?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">
   <extensions>
      <add assembly="NLog.Web.AspNetCore"/>
      <add assembly="NLog.WindowsEventLog"/>
   </extensions>

   <targets>
      <target xsi:type="File" name="allfile" fileName="Backoffice_template.log" layout="${longdate}|${event-properties:item=EventId_Id}|${uppercase:${level}}|${logger}|${message} ${exception:format=tostring} |action: ${aspnet-mvc-action} |user: ${aspnet-user-identity}" archiveEvery="Day" encoding="utf-8"
                   archiveNumbering = "Date"
                   archiveDateFormat = "yyyyMMdd_HHmmss" archiveOldFileOnStartup="false" maxArchiveDays="30" />
      <target name="EventLog" xsi:type="EventLog">
         <logLevel>Error</logLevel>
      </target>
      <target xsi:type="Console" name="lifetimeConsole" layout="${MicrosoftConsoleLayout}" />
   </targets>

   <rules>
      <logger name="*" minlevel="Trace" maxLevel="Warning" writeTo="allfile" />
      <logger name="Microsoft.*" maxLevel="Warning" final="true" />
      <logger name="System.Net.Http.*" maxlevel="Info" />
      <logger name="Microsoft.Hosting.Lifetime" minlevel="Info" writeTo="lifetimeConsole, ownFile-web" final="true" />
      <logger name="*" minlevel="Error" writeTo="EventLog" final="true" />
   </rules>
</nlog>

Logger is created like this:

var logger = LogManager.Setup().GetCurrentClassLogger();
