我的ASP.NET Core 2.1应用程序记录到Serilog文件汇，包括所有“通常的东西”——例如与应用程序相关的调试、监控、性能等。
但是，我们还需要将其他数据记录到单独的文件中。不是与应用程序相关的客户相关数据，这些数据应该存储到数据库中。但由于遗留原因，该系统上没有数据库，因此必须将这些数据保存到文件中。显然，它不能写入同一日志文件。
我可以简单地写入FileStream。但我更喜欢使用Serilog进行结构化日志记录。
那么是否有同时拥有两个记录器的方法？以便将不同的数据记录到不同的文件汇中。
(如果有的话，如何将它们注入到我的类中-现在我只注入ILogger<ClassName>。)
Serilog.Sinks.RollingFile NuGet包。根据需要可以使用其他Sinks。我使用asp.net Core 2.1。using Serilog;
using Serilog.Core;
public interface ICustomLogger
{
ILogger Log { get; }
}
public class CustomLogger : ICustomLogger
{
private readonly Logger _logger;
public ILogger Log { get { return _logger; } }
public CustomLogger( Logger logger )
{
_logger = logger;
}
}
using Serilog;
...
public void ConfigureServices( IServiceCollection services )
{
...
ICustomLogger customLogger = new CustomLogger( new LoggerConfiguration()
.MinimumLevel.Debug()
.WriteTo.RollingFile( @"Logs\CustomLog.{Date}.log", retainedFileCountLimit: 7 )
.CreateLogger() );
services.AddSingleton( customLogger );
...
}
using Serilog;
...
...
ICustomLogger customLogger = new CustomLogger( new LoggerConfiguration()
.MinimumLevel.Debug()
.WriteTo.RollingFile( @"Logs\CustomLog.{Date}.log", retainedFileCountLimit: 7 )
.CreateLogger() );
builder.Services.AddSingleton( customLogger );
...
public class MyTestController : Controller
{
private readonly ICustomLogger _customLogger;
public MyTestController( ICustomLogger customLogger )
{
_customLogger = customLogger;
}
public IActionResult Index()
{
...
_customLogger.Log.Debug( "Serving Index" );
...
}
}
Serilog.Sinks.Map可以实现这一点，并包括一个文件记录的示例：
Log.Logger = new LoggerConfiguration()
.WriteTo.Map("EventId", "Other", (name, wt) => wt.File($"./logs/log-{name}.txt"))
.CreateLogger();
You need to import package Serilog.Sinks.File
Then you have to configure Serilog.
In program.cs do following thing.
Log.Logger = new LoggerConfiguration()
.MinimumLevel.Debug()
.MinimumLevel.Override("Microsoft", LogEventLevel.Information)
.Enrich.FromLogContext()
.WriteTo.File(
@"<<your log file path>>",
fileSizeLimitBytes: 10000000,
rollOnFileSizeLimit: true,
shared: true,
flushToDiskInterval: TimeSpan.FromSeconds(1))
.CreateLogger();
public static IWebHost BuildWebHost(string[] args) =>
WebHost.CreateDefaultBuilder(args)
.UseStartup<Startup>()
.UseSerilog() // <-- Add this line
.Build();

我使用了EventId属性。这只是演示如何根据eventId使用不同的文件，但对于您的需求，您需要自己实现其他内容。
Program.cs
public class Program
{
public static void Main(string[] args)
{
Log.Logger = new LoggerConfiguration()
.WriteTo.Logger(cc => cc.Filter.ByIncludingOnly(WithProperty("EventId",1001)).WriteTo.File("Test1001.txt",flushToDiskInterval: TimeSpan.FromSeconds(1)))
.WriteTo.Logger(cc => cc.Filter.ByIncludingOnly(WithProperty("EventId", 2001)).WriteTo.File("Test2001.txt", flushToDiskInterval: TimeSpan.FromSeconds(1)))
.CreateLogger();
CreateWebHostBuilder(args).Build().Run();
}
public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
WebHost.CreateDefaultBuilder(args).UseSerilog()
.UseStartup<Startup>();
public static Func<LogEvent, bool> WithProperty(string propertyName, object scalarValue)
{
if (propertyName == null) throw new ArgumentNullException("propertyName");
ScalarValue scalar = new ScalarValue(scalarValue);
return e=>
{
LogEventPropertyValue propertyValue;
if (e.Properties.TryGetValue(propertyName, out propertyValue))
{
var stValue = propertyValue as StructureValue;
if (stValue != null)
{
var value = stValue.Properties.Where(cc => cc.Name == "Id").FirstOrDefault();
bool result = scalar.Equals(value.Value);
return result;
}
}
return false;
};
}
}
我的 HomeController.cs
public class HomeController : Controller
{
ILogger<HomeController> logger;
public HomeController(ILogger<HomeController> logger)
{
this.logger = logger;
}
public IActionResult Index()
{
logger.Log(LogLevel.Information,new EventId(1001), "This is test 1");
logger.Log(LogLevel.Information, new EventId(2001), "This is test 2");
return View();
}
}
注意：最重要的是您必须使用某种类型的过滤器。
