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

Question

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，如何创建标准测试？现在，我通过使用resource "azurerm_resource_group_template_deployment" …来创建资源。 ;请参阅gist.github.com/alexs77/0b2bd07aae7fbf22bd3c145132475e7d具体如何操作。

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？我对这部分感到困惑:

# …
resource "azurerm_monitor_metric_alert" "example" {
  # …
  criteria {
    metric_name      = "???"
    metric_namespace = "???"
    # …
  }
# …

那里使用的正确值是什么？

我知道这篇古老的博客文章 Creating an Application Insights Web Test and Alert Programmatically从 2015 年到 6 年前。它会让您转到Azure Resource Explorer :

In Resource Explorer, open your subscription and resource group, then providers, Microsoft Insights. There you’ll see two folders that will be important to us today: webtests and alertrules.

当我转到“microsoft.insights”时，“文件夹”alertrules不存在吗。

Answer 1

I'm trying to create an Alert Rule for an Application Insights →Availability → Standard (preview) test. First off, how do you create astandard test?

由于Standard测试是预览功能，目前尚未添加到terraform-azurerm-provider中。目前只能从ARM 模板进行部署。目前只能从 Terraform 部署 Classic 测试。

But even if it were a azurerm_application_insights_web_test, how wouldan Alert Rule (ie. azurerm_monitor_metric_alert - right?) look like?

您不必使用条件/动态条件，而应该使用application_insights_web_test_location_availability_criteria。因此，不需要 metric_name 和 metric_namespace 。使用该代码进行带有警报规则的经典 Web 测试将如下所示:

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

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
  }
}
