NLog 不记录（Windows 服务）

Question

我有一个 windows 服务，我正在将其从我自己的日志记录转换为 NLog。我在以前的 windows 服务应用程序中使用过 NLog，感觉我知道我在做什么。但它没有记录:(

我有以下 NLog 配置：

<?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"
      xsi:schemaLocation="http://www.nlog-project.org/schemas/NLog.xsd NLog.xsd"
      autoReload="true"
      throwExceptions="false"
      internalLogLevel="On" internalLogFile="c:\temp\nlog-internal.log" >

  <variable name="DebugInfoLayout" value="[${date:format=MM/dd/yyyy h\:mm\:ss tt}] [${gdc:item=location}]  |  ${level}  |  ${message}" />
  <variable name="InfoLayout" value="[${date:format=MM/dd/yyyy h\:mm\:ss tt}] ${gdc:item=SoftwareName} Version ${gdc:item=SoftwareVersion}  -  ${message}" />
  <variable name="LogLayout" value="[${date:format=MM/dd/yyyy h\:mm\:ss tt}] ${message}" />
  <variable name="logDir" value="${basedir}/LogFiles" />
  <variable name="ArchiveDir" value="${basedir}/LogFiles/Archive" />

  <targets async="true">
    <target name="Errors" xsi:type="File" fileName="${logDir}/errors.log" layout="${LogLayout}" keepFileOpen="false" archiveFileName="${ArchiveDir}/errors_${shortdate}.{##}.log" archiveNumbering="Sequence" archiveEvery="Day" maxArchiveFiles="30" archiveOldFileOnStartup="true" />
    <target name="Info" xsi:type="File" fileName="${logDir}/info.log" layout="${InfoLayout}"  keepFileOpen="false" archiveFileName="${ArchiveDir}/info_${shortdate}.{##}.log" archiveNumbering="Sequence" archiveEvery="Day" maxArchiveFiles="30"/>
    <target name="Debug" xsi:type="File" fileName="${logDir}/debug.log" layout="${DebugInfoLayout}"  keepFileOpen="false" archiveFileName="${ArchiveDir}/debug_${shortdate}.{##}.log" archiveNumbering="Sequence" archiveEvery="Day" maxArchiveFiles="30" />  
  </targets>

  <rules>
    <logger name="Errors" minlevel="Trace" maxlevel="Fatal" writeTo="Errors" />
    <logger name="Info" minlevel="Trace" maxlevel="Warn" writeTo="Info" />
    <logger name="Debug" minlevel="Trace" maxlevel="Fatal" writeTo="Debug" />
  </rules>
</nlog>

对我来说，这看起来是正确的。它与我的其他应用程序相同。从代码的角度来看，我的 service.vb 文件中有这个：

'NLog Instances
Dim errorLogger As NLog.Logger = NLog.LogManager.GetLogger("Errors")
Dim infoLogger As NLog.Logger = NLog.LogManager.GetLogger("Info")
Dim debugLogger As NLog.Logger = NLog.LogManager.GetLogger("Debug")

然后在下面的子程序中：

    Try
    Catch ex As Exception
        WritetoNLog(errorlogger, NLog.LogLevel.Error, System.Reflection.MethodInfo.GetCurrentMethod.Name, ex.Message)
        WritetoNLog(errorlogger, NLog.LogLevel.Error, System.Reflection.MethodInfo.GetCurrentMethod.Name, ex.InnerException.ToString)
    End Try

然后是这个简单的例程：

Public Sub WritetoNLog(ByRef logger As NLog.Logger, ByVal nlogtype As NLog.LogLevel, ByVal location As String, message As String)
    NLog.GlobalDiagnosticsContext.Set("location", String.Format("{0,-35}", location))

    Select Case nlogtype
        Case NLog.LogLevel.Trace
            logger.Trace(message)
        Case NLog.LogLevel.Fatal
            logger.Fatal(message)
        Case NLog.LogLevel.Info
            logger.Info(message)
        Case NLog.LogLevel.Debug
            logger.Debug(message)
        Case NLog.LogLevel.Error
            logger.Error(message)
        Case NLog.LogLevel.Warn
            logger.Warn(message)
    End Select

    NLog.LogManager.Flush()

End Sub

Answer 1

这是一个错误 internalLogLevel="On" 应该是 internalLogLevel="Trace"（或类似的）。
