一、配置

以下配置保留100个文件

ps:不加"Enrich": $"FromLogContext"$ 可能会导致程序直接死机

复制代码

  "Serilog": {
    "MinimumLevel": "Debug",
    "Enrich": ["FromLogContext"],
    "WriteTo": [
      {
        "Name": "File",
        "Args": {
          "path": "logs/info-.txt",
          "restrictedToMinimumLevel": "Information",
          "rollingInterval": "Day",
          "fileSizeLimitBytes": "314572800",
          "rollOnFileSizeLimit": "true",
          "retainedFileCountLimit": 100,
          "outputTemplate": "{Timestamp:yyyy-MM-dd HH:mm:ss.fff} [{Level:u3}] {Message:lj}{NewLine}{Exception}"
        }
      },
      {
        "Name": "File",
        "Args": {
          "path": "logs/error-.txt",
          "restrictedToMinimumLevel": "Error",
          "rollingInterval": "Day",
          "fileSizeLimitBytes": "314572800",
          "rollOnFileSizeLimit": "true",
          "retainedFileCountLimit": 100,
          "outputTemplate": "{Timestamp:yyyy-MM-dd HH:mm:ss.fff} [{Level:u3}] {Message:lj}{NewLine}{Exception}"
        }
      },
      {
        "Name": "File",
        "Args": {
          "path": "logs/warn-.txt",
          "restrictedToMinimumLevel": "Warning",
          "rollingInterval": "Day",
          "fileSizeLimitBytes": "314572800",
          "rollOnFileSizeLimit": "true",
          "retainedFileCountLimit": 100,
          "outputTemplate": "{Timestamp:yyyy-MM-dd HH:mm:ss.fff} [{Level:u3}] {Message:lj}{NewLine}{Exception}"
        }
      },
      {
        "Name": "File",
        "Args": {
          "path": "logs/debug-.txt",
          "restrictedToMinimumLevel": "Debug",
          "rollingInterval": "Day",
          "fileSizeLimitBytes": "314572800",
          "rollOnFileSizeLimit": "true",
          "retainedFileCountLimit": 100,
          "outputTemplate": "{Timestamp:yyyy-MM-dd HH:mm:ss.fff} [{Level:u3}] {Message:lj}{NewLine}{Exception}"
        }
      }
    ]
  }

二、使用

复制代码

            Log.Logger = new LoggerConfiguration()
                .ReadFrom.Configuration(builder.Configuration)
                .CreateLogger();
            builder.Host.UseSerilog();
