Azure Function + Application Insights - 不跟踪 SQL 查询

Question

我们有一个 Http 触发的 Azure 函数 (.NET Core 3.1)。无论出于何种原因，我们无法获得详细的 SQL 依赖性跟踪，我们看到的是：tcp:ourdbserver.database.windows.net,1433 | TestDB.

在本地调试和部署到 Azure 时都不起作用。我们已经安装了最新的 ApplicationInsights nuget 包（见下文）：

并且在 StartUp 中我们选择加入 SQL Microsoft 文档建议的文本收集 here:

任何人都可以阐明我们缺少的东西吗？

更新：

这就是我们在 host.json:

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

下面是在本地调试时输出到调试控制台的内容：

ApplicationInsightsLoggerOptions
{
  "SamplingSettings": {
    "EvaluationInterval": "00:00:15",
    "InitialSamplingPercentage": 100.0,
    "MaxSamplingPercentage": 100.0,
    "MaxTelemetryItemsPerSecond": 20.0,
    "MinSamplingPercentage": 0.1,
    "MovingAverageRatio": 0.25,
    "SamplingPercentageDecreaseTimeout": "00:02:00",
    "SamplingPercentageIncreaseTimeout": "00:15:00"
  },
  "SamplingExcludedTypes": null,
  "SamplingIncludedTypes": null,
  "SnapshotConfiguration": null,
  "EnablePerformanceCountersCollection": true,
  "HttpAutoCollectionOptions": {
    "EnableHttpTriggerExtendedInfoCollection": true,
    "EnableW3CDistributedTracing": true,
    "EnableResponseHeaderInjection": true
  },
  "LiveMetricsInitializationDelay": "00:00:15",
  "EnableLiveMetrics": true,
  "EnableDependencyTracking": true
}

Answer 1

如下更新 host.json 中的日志记录部分以允许 Information 级别的日志（请注意，我在上面发布的现有配置中添加了 logLevel）。如果您不指定，默认情况下它是警告。如注释 here, dependencies are logged with Information level. Also note excludedTypes (not samplingExcludedTypes) should be inside samplingSettings as per documentation.

中所述

{
  "version": "2.0",
  "logging": {
    "applicationInsights": {
        "samplingSettings": {
            "isEnabled": true,
            "excludedTypes": "Dependency;Request"
        }
    },
    "logLevel": {"default": "Information"}
  }
}

Answer 2

您需要在 host.json 文件中配置 dependencyTrackingOptions.enableSqlCommandTextInstrumentation:

{
  "logging": {
    "applicationInsights": {
      "dependencyTrackingOptions": {
        "enableSqlCommandTextInstrumentation": true
      }
    }
  }
}
