Azure函数表绑定(bind)产生大量日志记录噪音

Question

刚刚将 azure 函数从 v3 升级到 v4 和 dotnet6。注意到运行时绑定(bind)也需要更新。

我刚刚对其进行了测试，并注意到有很多详细的日志记录来自表绑定(bind)以及我自己的日志记录。我怎样才能排除这个？我应该排除它吗？当观察活原木时，很难从树上看到木材

[FunctionName("Function2")]
        public static async Task<IActionResult> Run(
            [HttpTrigger(AuthorizationLevel.Anonymous, "get", "post", Route = null)] HttpRequest req,
            [Table("Keys", Connection = "TableStorage")] TableClient keysTable,
            ILogger log)
        {
            log.LogInformation("C# HTTP trigger function processed a request.");
         
            if (keysTable != null)
            {
                try
                {
                    var item2 = keysTable.GetEntity<TableEntity>("jon", "test");  
                }
                catch (Exception)
                {
                    log.LogError("key not present");
                }
            }

            log.LogInformation("C# HTTP trigger function completed.");
            return new OkObjectResult(new { });
        }

我原以为只会显示我的日志记录。

我已通读此内容并发现了这一 block 信息

https://learn.microsoft.com/en-us/azure/azure-functions/functions-monitoring#disable-built-in-logging

Dependencies Starting with version 2.x of Functions, Application Insights automatically collects data on dependencies for bindings that use certain client SDKs. Application Insights distributed tracing and dependency tracking aren't currently supported for C# apps running in an isolated worker process. Application Insights collects data on the following dependencies:

Azure Cosmos DB
Azure Event Hubs
Azure Service Bus
Azure Storage services (Blob, Queue, and Table)

没有说明如何禁用它

Host.json 文件

{
  "version": "2.0",
  "logging": {
    "applicationInsights": {
      "samplingSettings": {
        "isEnabled": true,
        "excludedTypes": "Request"
      }
    }
  }
}

Answer 1

更新 host.json 文件以仅包含这些类别的错误日志对我有用。

{
  "version": "2.0",
  "logging": {
    "logLevel": {
      "default": "Information",
      "Azure.Core": "Error",
      "Azure.Messaging.ServiceBus": "Error"
      //others categories you have noise
    }
  }
}
