将 Error 及以上写入 stderr，将 Verbose 及以上写入 stdout

Question

如何设置 NLog 中的配置将错误及以上记录到 stderr 并将详细及以上记录到 stdout?

// Setting error="true" logs all messages to stderr but I want to log only error messages
// How would I configure to log err messages to stderr and others to stdout?
 <target name="console" xsi:type="Console" error="true">
    <layout xsi:type="JsonLayout">
      <attribute name="Level" layout="${level}" />
      <attribute name="Timestamp" layout="${longdate}" />
      <attribute name="Message" layout="${message}" />
    </layout>
  </target>

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

 var logger = LogManager.GetCurrentClassLogger();
 logger.Error("Error Message"); // Writes to stderr
 logger.Verbose("Verbose Message"); // Writes to  stderr but must write to stdout

非常感谢任何帮助。

一个解决方案可以是两个目标：

 <target name="console" xsi:type="Console">
    <layout xsi:type="JsonLayout">
      <attribute name="Level" layout="${level}" />
      <attribute name="Timestamp" layout="${longdate}" />
      <attribute name="Message" layout="${message}" />
    </layout>
 </target>
 <target name="console_error" xsi:type="Console" error="true">
    <layout xsi:type="JsonLayout">
      <attribute name="Level" layout="${level}" />
      <attribute name="Timestamp" layout="${longdate}" />
      <attribute name="Message" layout="${message}" />
      <attribute name="Exception" layout="${exception}" />
    </layout>
 </target>

然后有两条规则：

<logger name="*" minlevel="Warn" writeTo="debug,console_error" />
<logger name="*" maxLevel="Info" writeTo="debug,console" />

将 Error 及以上写入 stderr，将 Verbose 及以上写入 stdout

Write Error and above to stderr and Verbose and above to stdout
