azure - 使用 Terraform（或 ARM 模板）为 Webtest 创建 Azure 警报规则？

Answer 1

我正在尝试为 Application Insights → 可用性 → 标准（预览）测试创建警报规则。首先，您如何创建标准测试？

由于StandardTest 是一个预览功能，它目前没有添加到terraform-azurerm-provider中。到目前为止，它只能从ARM 模板部署。目前只能Classic从Terraform部署测试。

但即使它是 azurerm_application_insights_web_test，警报规则（即 azurerm_monitor_metric_alert - 对吗？）会是什么样子？

您不必使用，criteria / dynamic criteria而是应该使用application_insights_web_test_location_availability_criteria. 所以，metric_name并且metric_namespace不需要。使用带有警报规则的经典 Web 测试代码将如下所示：

provider "azurerm" {
  features{}
}
data "azurerm_application_insights" "example" {
  name="ansumantestapp"
  resource_group_name = "ansbalrg"
}

resource "azurerm_application_insights_web_test" "example" {
  name                    = "tf-test-appinsights-webtest"
  location                = data.azurerm_application_insights.example.location
  resource_group_name     = data.azurerm_application_insights.example.resource_group_name
  application_insights_id = data.azurerm_application_insights.example.id
  kind                    = "ping"
  frequency               = 300
  timeout                 = 60
  enabled                 = true
  geo_locations           = ["us-ca-sjc-azr", "us-va-ash-azr"]

  configuration = <<XML
<WebTest Name="WebTest1" Id="ABD48585-0831-40CB-9069-682EA6BB3583" Enabled="True" CssProjectStructure="" CssIteration="" Timeout="0" WorkItemIds="" xmlns="http://microsoft.com/schemas/VisualStudio/TeamTest/2010" Description="" CredentialUserName="" CredentialPassword="" PreAuthenticate="True" Proxy="default" StopOnError="False" RecordedResultFile="" ResultsLocale="">

}
resource "azurerm_monitor_action_group" "main" {
  name                = "example-actiongroup"
  resource_group_name = data.azurerm_application_insights.example.resource_group_name
  short_name          = "exampleact"
  email_receiver {
    name                    = "sendtoadmin"
    email_address           = "myemailid"
    use_common_alert_schema = true
  }
}

resource "azurerm_monitor_metric_alert" "example" {
  name                = "example-metricalert"
  resource_group_name = data.azurerm_application_insights.example.resource_group_name
  scopes = [azurerm_application_insights_web_test.example.id,data.azurerm_application_insights.example.id]
  description         = "PING test alert"

application_insights_web_test_location_availability_criteria {
  web_test_id = azurerm_application_insights_web_test.example.id
  component_id = data.azurerm_application_insights.example.id
  failed_location_count = 2
}

  action {
    action_group_id = azurerm_monitor_action_group.main.id
  }
}
