Question

当我在本地调试功能应用程序时，我现在在控制台窗口中收到大量日志消息。

它看起来像这样：

[2020-10-04T20:48:31.130] corehub-control-03: Lease renewal with token 23fb44c2-49e4-4e1f-9ff4-058612d66f1e succeeded

[2020-10-04T20:48:32.771] corehub-control-03: Successfully acquired lease

失败和错误很好，但是租约获取和续订消息似乎很嘈杂。我在读取自己的调试消息时遇到了麻烦，随着应用程序继续运行，它会不断滚动。

有什么办法可以关闭它们？我已经尝试了许多设置，但看起来还是很健谈。

TIA

您可以在host.json中添加部分以过滤日志。

例如，如果您只想查看错误，则host.json应如下所示：

{
    "version": "2.0",
  "logging": {
    "applicationInsights": {
      "samplingExcludedTypes": "Request",
      "samplingSettings": {
        "isEnabled": true
      }
    },
    "logLevel": {
      "Function": "Error",
    }
  }
}

检查过滤器和功能应用程序的日志级别：
