在AspNetMvc中使用日志面板

示例源碼 : https://github.com/liangshiw/LogDashboard/tree/master/samples/NfxAspNetMvc

使用VisualStudio創建一個AspNetMvc項目,命名為 NfxAspNetMvc

配置Nlog

在程序包管理控制台安裝 Nlog.Web
Install-Pakcage Nlog.Web

將下面的Nlog.config添加到項目中,並且配置復制到目錄

<?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"
      throwExceptions="false"
      internalLogLevel="Off" internalLogFile="c:\temp\nlog-internal.log">

  <!-- optional, add some variables
  https://github.com/nlog/NLog/wiki/Configuration-file#variables
  -->
  <variable name="myvar" value="myvalue"/>

  <!--
  See https://github.com/nlog/nlog/wiki/Configuration-file
  for information on customizing logging rules and outputs.
   -->
  <targets>

    <target xsi:type="file" name="File" fileName="${basedir}/logs/${shortdate}.log"
            layout="${longdate}||${level}||${logger}||${message}||${exception:format=ToString:innerFormat=ToString:maxInnerExceptionLevel=10:separator=\r\n}||end" />
    <!--
    Write events to a file with the date in the filename.
    -->
  </targets>

  <rules>
    <logger name="*" minlevel="Debug" writeTo="file" />
    <!-- add your logging rules here -->

    <!--
    Write all events with minimal level of Debug (So Debug, Info, Warn, Error and Fatal, but not Trace)  to "f"
    <logger name="*" minlevel="Debug" writeTo="f" />
    -->
  </rules>
</nlog>

打開WebConfig 將下面的modules節點配置復制到 WebConfig中

<modules runAllManagedModulesForAllRequests="true">
      <remove name="TelemetryCorrelationHttpModule" />
      <add name="TelemetryCorrelationHttpModule" type="Microsoft.AspNet.TelemetryCorrelation.TelemetryCorrelationHttpModule, Microsoft.AspNet.TelemetryCorrelation" preCondition="integratedMode,managedHandler" />
      <add name="NLog" type="NLog.Web.NLogHttpModule, NLog.Web" />
    </modules>

打開 HomtController 使用logger 寫一條日志

public ActionResult Index()
{
    //var logger = logger
    var logger = LogManager.GetCurrentClassLogger();
    logger.Info("HomeController index action");
    return View();
}

安裝LogDashboard

logDashboard在AspNetMvc中依賴Owin中間件,首先我們先安裝 Microsoft.Owin.Host.SystemWeb 包

Install-Package Microsoft.Owin.Host.SystemWeb

下面安裝LogDashboard 因為是預發布版,在安裝的時候需要指定版本

Install-Package LogDashboard -Version 1.1.0-beta

最后我們添加Owin Startup類,在添加時搜索owin會出現該條目,在Startup中配置LogDashboard中間件

public void Configuration(IAppBuilder app)
{
    app.MapLogDashboard(typeof(Startup).Assembly, opt =>
    {
        opt.SetRootPath(AppContext.BaseDirectory);
    });
}

這時運行項目並導航到 /logdashboard 就會看到日志面板,與我們添加的日志消息 HomeController index action
