azure - 本地运行的 Azure 函数 - 无法从“详细”控制台设置日志记录级别充满垃圾

问题描述

github上似乎有很多答案，stackoverflow上有一些答案，但它们都不再有效/工作了。我正在尝试开发一个 azure-functions 节点应用程序并在本地运行它会使控制台充满大量无用的垃圾。我一直在尝试更改函数的日志记录级别但无济于事，我已将它们添加到我的 function.json 和 host.json 以及 local.settings.json 但它们没有任何区别。

大多数地方告诉我将它添加到“host.json”，但 tsling 抛出了“host.json 中不允许的属性 x”，尽管如此我忽略了它并尝试了。

我试过了：

{
  "logger": {
    "categoryFilter": {
      "defaultLevel": "Information",
      "categoryLevels": {
        "Host.Results": "Error",
        "Function": "Error",
        "Host.Aggregator": "Information"
      }
    },
    "aggregator": {
      "batchSize": 1000,
      "flushTimeout": "00:00:30"
    }
  },
  "applicationInsights": {
    "sampling": {
      "isEnabled": true,
      "maxTelemetryItemsPerSecond" : 5
    }
  }
}

也只有“错误”，但没有运气。

有人提到尝试：

{
  "logger": {
    "categoryFilter": {
      "categoryLevels": {
        "Function": "Error"
      }
    }
  }
}

这也没有什么不同。

另外，这里有一小部分无用垃圾淹没了相关日志：

@Ian 的解决方案有效，但仍然会产生一些轻微的垃圾，例如：

[Azure] [1/14/2020 1:03:47 PM] Restarting host.

[Azure] [1/14/2020 1:03:47 PM]     },
[Azure] [1/14/2020 1:03:47 PM]     "console": {

[Azure] [1/14/2020 1:03:47 PM]     }
[Azure] [1/14/2020 1:03:47 PM]   }
[Azure] [1/14/2020 1:03:47 PM] }
[Azure] [1/14/2020 1:03:47 PM] Reading functions metadata
[Azure] [1/14/2020 1:03:47 PM] 1 functions found

还有几行。

能够变得更瘦会很好，但如果不是，它仍然很好。

解决方案

您似乎正在使用带有 Azure Functions 2.0 主机的 Azure Functions 1.0 格式的配置文件。请参阅 AF 2.0 配置文件架构的文档：https ://docs.microsoft.com/en-us/azure/azure-functions/functions-host-json#logging
