appsettings.json 中的 Serilog 过滤器不起作用

Question

我正在尝试在我的应用程序设置中使用 serilog 表达式实现日志过滤器，过滤所有“健康”相关日志。 这是我到目前为止的配置：

"Serilog": {
  "Using": [ "Serilog.Sinks.MSSqlServer" ],
  "MinimumLevel": "Debug",
  "WriteTo": [
    {
      "Name": "MSSqlServer",
      "Args": {
        "connectionString": "Data Source=XXX; Database=YYY; Integrated Security=True; TrustServerCertificate=true;",
        "sinkOptionsSection": {
          "tableName": "Logging",
          "autoCreateSqlDatabase": false,
          "autoCreateSqlTable": true
        },
        "columnOptionsSection": {
          "additionalColumns": [
            {
              "columnName": "RequestMethod",
              "dataLength": "8"
            },
            {
              "columnName": "StatusCode",
              "dataType": "Int"
            }
          ]
        },
        "Filter": [
          {
            "Name": "ByExcluding",
            "Args": {
              "expression": "RequestPath like '%/health%'"
            }
          }
        ]
      }
    }
  ],
  "Enrich": [ "FromLogContext", "WithMachineName", "WithThreadId" ],
  "Destructure": [
    {
      "Name": "ToMaximumDepth",
      "Args": { "maximumDestructuringDepth": 4 }
    },
    {
      "Name": "ToMaximumStringLength",
      "Args": { "maximumStringLength": 100 }
    },
    {
      "Name": "ToMaximumCollectionCount",
      "Args": { "maximumCollectionCount": 10 }
    }
  ],
  "Properties": {
    "Application": "Api"
  }
},

但是，与 HealthChecks 相关的消息继续记录在我的数据库中。

如何编写一个配置，通过仅包含、排除进行过滤或检查 Loggin 表中的列是否具有特定值？

谢谢

我阅读了关于 Serilog 表达式的 文档 ，但不太了解过滤器的工作原理：我可以使用哪些属性来过滤？我在哪里可以找到它们？它们是 MessageTemplate 列中的 {KEYS} 中的变量吗？我的自定义列怎么样：我可以过滤它们吗？

例如：MessageTemplate 'HTTP {RequestMethod} {RequestPath} 在 {Elapsed:0.0000} ms 中响应 {StatusCode} 中的消息为我提供了 {RequestPath} 变量，但是当我尝试在过滤器中使用它时（“表达式”： “RequestPath like '%/health%'”），没有任何反应。

Filter 部分位于 WriteTo 标记内的错误位置。 将其放在“Serilog”内部解决了问题。

  "Serilog": {
    "Using": [ "Serilog.Sinks.MSSqlServer" ],
