Serilog 不使用 Serilog.Sinks.MssqlServer 将日志写入 SQL 服务器

Question

我正在尝试使用 Serilog 设置日志记录机制。 我想将日志写入文件和 SQL 服务器数据库。

目前我可以将日志写入文件系统，但无法写入数据库。 我也做了与 Serilog 文档中相同的简单设置

谢谢你。

public class Program
{
        public static void Main(string[] args)
        {
            var logDB = @"Server=localhost;Initial Catalog=SHARED_NOTE;User ID=sa;Password=sql123;";
            var sinkOpts = new MSSqlServerSinkOptions();
            sinkOpts.TableName = "Logs";
            var columnOpts = new ColumnOptions();
            columnOpts.Store.Remove(StandardColumn.Properties);
            columnOpts.Store.Add(StandardColumn.LogEvent);
            columnOpts.LogEvent.DataLength = 2048;
            columnOpts.TimeStamp.NonClusteredIndex = true;

            Log.Logger = new LoggerConfiguration()
                .WriteTo.File(new CompactJsonFormatter(), "Log.json", rollingInterval: RollingInterval.Day)
                .WriteTo.Console(restrictedToMinimumLevel:Serilog.Events.LogEventLevel.Information)
                .WriteTo.MSSqlServer(
                        connectionString: logDB,
                        sinkOptions: sinkOpts,
                        columnOptions: columnOpts
                 )
                .CreateLogger();

            try
            {
                Log.Information("Application starting up.");

                CreateHostBuilder(args).Build().Run();
            }
            catch (Exception ex)
            {
                Log.Fatal(ex, "The application failed to start up correctly.");
            }
            finally
            {
                Log.CloseAndFlush();
            }
        }

        public static IHostBuilder CreateHostBuilder(string[] args) =>
            Host.CreateDefaultBuilder(args)
                .UseSerilog()
                .ConfigureWebHostDefaults(webBuilder =>
                {
                    webBuilder.UseStartup<Startup>();
                });
    }

我将AddLogging添加到startup.cs ：

services.AddLogging();

所有软件包都为 Web API 项目设置：

<Project Sdk="Microsoft.NET.Sdk.Web">

  <PropertyGroup>
    <TargetFramework>net5.0</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="FluentValidation" Version="10.3.6" />

评论没有足够的声誉，您是否尝试过关注这篇文章？ Serilog 日志到 SQL 。

您尚未添加日志记录表，但我将假设您遵循 Sink 并且它类似于或匹配此表？

TABLE [Log] (

   [Id] int IDENTITY(1,1) NOT NULL,
   [Message] nvarchar(max) NULL,
   [MessageTemplate] nvarchar(max) NULL,
   [Level] nvarchar(128) NULL,
   [TimeStamp] datetimeoffset(7) NOT NULL,
   [Exception] nvarchar(max) NULL,
   [Properties] xml NULL,
   [LogEvent] nvarchar(max) NULL

   CONSTRAINT [PK_Log]
     PRIMARY KEY CLUSTERED ([Id] ASC)

)

此外，在同一篇文章中，您可以在 Logger 设置之后添加以下代码来调试 SQL 连接

Serilog.Debugging.SelfLog.Enable(msg =>
{
    Debug.Print(msg);
    Debugger.Break();
});

所以在你的代码中它会是

Log.Logger = new LoggerConfiguration()
    .WriteTo.File(new CompactJsonFormatter(),
    "Log.json",
    rollingInterval: RollingInterval.Day)
            .WriteTo.Console(restrictedToMinimumLevel:Serilog.Events.LogEventLevel.Information)
            .WriteTo.MSSqlServer(
                    connectionString: logDB,
                    sinkOptions: sinkOpts,
                    columnOptions: columnOpts
             )
            .CreateLogger();

Serilog.Debugging.SelfLog.Enable(msg =>
{
    Debug.Print(msg);
    Debugger.Break();
});
