为什么自动发布后需要手动开启App Insights？

Question

为什么发布后应用洞察没有自动开启？

执行自动发布后，我在导航到门户中的应用程序见解时得到以下信息：

这是我在 ARM 模板中定义的方式：

{
  "type": "microsoft.insights/components",
  "kind": "web",
  "name": "[parameters('webAppName')]",
  "apiVersion": "2015-05-01",
  "location": "[parameters('location')]",
  "tags": {
    "[concat('hidden-link:', resourceGroup().id, '/providers/Microsoft.Web/sites/', parameters('webAppName'))]": "Resource",
    "displayName": "[parameters('webAppName')]"
  },
  "properties": {
    "Application_Type": "web"
  },
  "dependsOn": []
}

我做错了什么？ 为什么应用洞察没有自动开启？

请注意，我添加了以下应用程序设置：

为了让 Azure 门户显示与 Application Insights 的主动集成，您需要设置两个应用程序设置。原因是您还需要配置 Application Insights Agent Extension。

请注意，设置 InstrumentationKey（已弃用）或连接字符串可能足以让您的应用程序将遥测数据发送到 ApplicationInsights，例如如果您使用的是 ASP.NET Core 和相应的 Nuget 包。但您将需要门户的这两种设置才能显示活动集成。

Answer 2

接受的答案已过时。不建议将 APPINSIGHTS_INSTRUMENTATIONKEY 与 APPLICATIONINSIGHTS_CONNECTION_STRING 一起使用。最后提供者获胜。

不推荐使用检测密钥，我们应该改用 APPLICATIONINSIGHTS_CONNECTION_STRING。

否则提供的答案成立。更多信息在这里：

Answer 3

我必须设置 3 个应用程序设置才能自动注册并打开应用程序洞察（在本例中使用二头肌）：

{
  name: 'APPLICATIONINSIGHTS_CONNECTION_STRING'
  value: applicationInsights.properties.ConnectionString
}
{
  name: 'APPINSIGHTS_INSTRUMENTATIONKEY'
  value: applicationInsights.properties.InstrumentationKey
}
{
  name: 'ApplicationInsightsAgent_EXTENSION_VERSION'
  value: '~2'
}
