**セットアップ [#a8c75994]
-NuGet で [[NLog.Web.AspNetCore:https://www.nuget.org/packages/NLog.Web.AspNetCore]] をインストール
-プロジェクト直下に「nlog.config」を作成
<?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="Warn"
internalLogFile="c:\temp\internal-nlog.txt">
<!-- Load the ASP.NET Core plugin -->
<extensions>
<add assembly="NLog.Web.AspNetCore"/>
</extensions>
<!-- the targets to write to -->
<targets>
<!-- write logs to file -->
<target xsi:type="File" name="allfile" fileName="c:\var\log\nlog-all-${shortdate}.log"
layout="${longdate}|${event-properties:item=EventId.Id}|${logger}|${uppercase:${level}}|${message} ${exception}" />
<!-- another file log, only own logs. Uses some ASP.NET core renderers -->
<target xsi:type="File" name="ownFile-web" fileName="c:\var\log\nlog-own-${shortdate}.log"
layout="${longdate}|${event-properties:item=EventId.Id}|${logger}|${uppercase:${level}}| ${message} ${exception}|url: ${aspnet-request-url}|action: ${aspnet-mvc-action}" />
<!-- write to the void aka just remove -->
<target xsi:type="Null" name="blackhole" />
</targets>
<!-- rules to map from logger name to target -->
<rules>
<!--All logs, including from Microsoft-->
<logger name="*" minlevel="Trace" writeTo="allfile" />
<!--Skip Microsoft logs and so log only own logs-->
<logger name="Microsoft.*" minlevel="Trace" writeTo="blackhole" final="true" />
<logger name="*" minlevel="Trace" writeTo="ownFile-web" />
</rules>
</nlog>
-nlog.config のプロパティを開き、直接出力を「常に出力」にする
-Startup.cs を変更
public Startup(IConfiguration configuration, IHostingEnvironment env)
{
Configuration = configuration;
env.ConfigureNLog("nlog.config");
}
public void ConfigureServices(IServiceCollection Services)
{
//call this in case you need aspnet-user-authtype/aspnet-user-identity
services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();
}
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
//add NLog to ASP.NET Core
loggerFactory.AddNLog();
//add NLog.Web
app.AddNLogWeb();
-ログ出力
public class HomeController : Controller
{
private readonly ILogger<HomeController> _logger;
public HomeController(ILogger<HomeController> logger)
{
_logger = logger;
}
public IActionResult Index()
{
_logger.Fatal("致命的レベル");
_logger.Error("エラーレベル");
_logger.Warn("警告レベル");
_logger.Info("情報レベル");
_logger.Debug("デバッグレベル");
_logger.Trace("トレースレベル");
return View();
}
-ログ確認
