Serilog 多個文件 appsettings.json

Question

我試圖將 serilog 配置為寫入多個文件，但沒有任何運氣。 使用此配置它只是寫入第二個文件？

{
  "AllowedHosts": "*",
  "Serilog": {
    "Using": [ "Serilog.Sinks.File" ],
    "MinimumLevel": "Debug",
    "WriteTo": [
      {
        "Name": "File",
        "Args": {
          "path": "c:\\temp\\audit-.log",
          "rollingInterval": "Day",
          "restrictedToMinimumLevel": "Information"
        }
      },
      {
        "Name": "File",
        "Args": {
          "path": "c:\\temp\\error-.log",
          "rollingInterval": "Day",
          "restrictedToMinimumLevel": "Error"
        }
      }
    ]
  }
}

或者有什么方法可以將許多記錄器加載到具有來自 appsettings.json 的不同配置的軟件中。 像這樣的東西？

var errorLogConfiguration = new ConfigurationBuilder()
    .SetBasePath(Directory.GetCurrentDirectory())
    .AddJsonFile("appsettings.json", optional: false, reloadOnChange: true)
    .AddJsonFile($"appsettings.{Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT") ?? "Production"}.json", optional: true)
    .AddEnvironmentVariables()
    .Build();

_log = new LoggerConfiguration()
    .ReadFrom
    .Configuration(errorLogConfiguration)
    .CreateLogger();

我找到了解決方案。 為 appsettings.json、ErrorLog 和 AuditLog 創建了單獨的部分。

  "ErrorLog": {
    "Using": [ "Serilog.Sinks.File" ],
    "MinimumLevel": "Debug",
    "WriteTo": [
      {
        "Name": "File",
        "Args": {
          "path": "c:\\temp\\error-.log",
          "rollingInterval": "Day",
          "restrictedToMinimumLevel": "Error"
        }
      }
    ]
  },
  "AuditLog": {
    "Using": [ "Serilog.Sinks.File" ],
    "MinimumLevel": "Debug",
    "WriteTo": [
      {
        "Name": "File",
        "Args": {
          "path": "c:\\temp\\audit-.log",
          "rollingInterval": "Day",
          "restrictedToMinimumLevel": "Information"
        }
      }
    ]
  }

現在我可以創建 2 個單獨的記錄器：

            var errorLogConfiguration = new ConfigurationBuilder()
                .SetBasePath(Directory.GetCurrentDirectory())
                .AddJsonFile("appsettings.json", optional: false, reloadOnChange: true)
                .AddJsonFile($"appsettings.{Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT") ?? "Production"}.json", optional: true)
                .AddEnvironmentVariables()
                .Build();

            var errorSection = errorLogConfiguration.GetSection("ErrorLog");
            var auditSection = errorLogConfiguration.GetSection("AuditLog");

            _log = new LoggerConfiguration()
                .ReadFrom
                .ConfigurationSection(errorSection)
                .CreateLogger();

            _auditLog = new LoggerConfiguration()
                .ReadFrom
                .ConfigurationSection(auditSection)
                .CreateLogger();

哪個更適合我的需要。

由於 Serilog 和任何接收器的簡單文檔而苦苦掙扎了幾天之后，這最終對我有用，而無需創建任何單獨的記錄器：

"Serilog": {
    "Using": [ "Serilog.Sinks.Async" ],
    "MinimumLevel": "Verbose",
    "Enrich": [ "FromLogContext", "WithDemystifiedStackTraces" ],
    "WriteTo:Information": {
        "Name": "Async",
        "Args": {
            "Configure": [
                {
                    "Name": "RollingFile",
                    "Args": {
                        "RestrictedToMinimumLevel": "Information",
                        "Formatter": "FOOINC.API.Configuration.Logging.CustomRenderedCompactJsonFormatter, FOOINC.API.Configuration",
                        "PathFormat": "_logs\\info\\info-log.json"
                    }
                }
            ]
        }
    },
    "WriteTo:Error": {
        "Name": "Async",
        "Args": {
            "Configure": [
                {
                    "Name": "RollingFile",
                    "Args": {
                        "RestrictedToMinimumLevel": "Error",
                        "Formatter": "FOOINC.API.Configuration.Logging.CustomRenderedCompactJsonFormatter, FOOINC.API.Configuration",
                        "PathFormat": "_logs\\errors\\error-log.json"
                    }
                }
            ]
        }
    }
}

希望這可以幫助那里的任何人！！

由於缺乏有關 Serilog 的文檔，我的發現經過一段時間的錯誤，重試並幾乎放棄。 他們在 GitHub 上有所行動： https : //github.com/serilog/serilog-filters-expressions/issues/27 。 幾乎每個線程都得出相同的結論，即您必須創建一個 SUBLOGGER。 這是我的實現。 對於此實現，您需要以下插件：

• 串行過濾器
• 水槽

• 串行日志異步

  "Serilog": { "Using": [ "Serilog.Sinks.File" ], "MinimumLevel": { "Default": "Information", "Override": { "Microsoft": "Warning", "System": "Warning" } }, "WriteTo:Information": { //this name here can be changed "Name": "Logger", //this name here is essential "Args": { "configureLogger": { "Filter": [ { "Name": "ByIncludingOnly", "Args": { "expression": "@Level = 'Information'" } } ], "WriteTo": [ { "Name": "Async", //i use async plugin from serilog "Args": { "configure": [ { "Name": "File", "Args": { "path": "Logs/Log_.txt", "formatter": "Serilog.Formatting.Json.JsonFormatter, Serilog", "rollingInterval": "Day", "retainedFileCountLimit": 7 } } ] } } ] } } },

通過配置文件幾乎沒有關於記錄器設置的文檔。 任何人都可以幫忙 - 只是一個使用記錄器設置的例子。 在示例中 - 所有日志都寫在一個 sample.txt 中。 記錄某個 API / api/health 的調用 - 在一個單獨的文件中，不包含在 sample.txt 中。 還有一個示例廣告 - IMyLogger-寫入單獨的 SampleMy.txt。 您可以添加多個部分，並按不同標准划分日志。 最好將本地日志級別設置為最小，它們將被全局級別覆蓋。 全局過濾器將從所有子記錄器中排除日志（我不使用它）。 PS抱歉英語不好）

我對這個問題做了一些測試。 好消息是您的配置有效。 您的錯誤文件可能未創建，因為沒有記錄錯誤。

當第一條消息登錄到該文件時，Serilog 將創建日志文件。 如果您運行這個簡單的程序並（取消）注釋錯誤記錄，您可以確認這一點。

class Program
{
    static void Main(string[] args)
    {
        var errorLogConfiguration = new ConfigurationBuilder()
            .SetBasePath(Directory.GetCurrentDirectory())
            .AddJsonFile("settings.json", optional: false, reloadOnChange: true)
            .Build();

        var log = new LoggerConfiguration()
            .ReadFrom
            .Configuration(errorLogConfiguration)
            .CreateLogger();
        log.Warning("Warning");
        log.Error("Error");
    }
}
