Question

我想在Serilog文件名中使用UTC DateTime。我在appseting.json文件中将以下配置用于serilog。

"Serilog": {
    "Using": [],
    "MinimumLevel": {
      "Default": "Information",
      "Override": {
        "Microsoft": "Warning",
        "System": "Warning"
      }
    },
    "Enrich": [
      "FromLogContext",
      "WithMachineName",
      "WithProcessId",
      "WithThreadId"
    ],
    "WriteTo": [
      {
        "Name": "Console"
      },
      {
        "Name": "File",
        "Args": {
          "path": "Logs\\log-.json",
          "formatter": "Serilog.Formatting.Compact.CompactJsonFormatter, Serilog.Formatting.Compact",
          "rollingInterval": "Hour",
          "shared": true
        }
      }
    ]
  }

和下面是我用于serilog的program.cs文件代码。

public static void Main(string[] args)
        {

            var configuration = new ConfigurationBuilder()
                .AddJsonFile("appsettings.json").Build();

            Log.Logger = new LoggerConfiguration()
                .ReadFrom.Configuration(configuration)
                .CreateLogger();
            try
            {
                CreateHostBuilder(args).Build().Run();
            }
            catch (Exception e)
            {
                Log.Fatal(e, "The Application failed to start correctly");
            }
            finally
            {
                Log.CloseAndFlush();
            }
        }

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

当前，serilog生成的日志文件名为log-2020091323.json，它不是UTC DateTime。我正在使用asp.net core 3.1。

您可以使用Install-Package Serilog.Sinks.Map nuget软件包并在Serilog设置中对其进行配置，以将其存档，如下面的代码示例所示

Log.Logger = new LoggerConfiguration()
    .MinimumLevel.Information()
    // Ex: UtcDateTime value '202009201010'
    .WriteTo.Map("UtcDateTime", DateTime.UtcNow.ToString("yyyyMMddHHmm")
                    , (UtcDateTime, wt) => wt.File($"logs/log-{UtcDateTime}.txt"))
    .CreateLogger();

Log.Information("Hello, Serilog!");

Log.CloseAndFlush(); // Ex: log file name 'log-202009201010.txt'

如果您需要每小时对其进行配置，则此代码每分钟将日志保存到新文件，请使用DateTime.UtcNow.ToString("yyyyMMddHH")或DateTime.UtcNow.ToString("yyyyMMdd") 天。
