使用 Terraform 为 Azure 中同一订阅下的所有虚拟机创建警报

Question

**I am trying to deploy below terraform alert for all VMs under my subscription, and subscription id I've kept it in variables file. But its throwing below error.

另外，我如何为下面的模板将类型定义为 MultipleResourceMultipleMetricCriteria，就像在 ARM 模板中一样，我们可以将此类型定义为 odata.type，但是当我在 terraform 中尝试 odata_type 时，它不接受它。还有什么方法可以在运行时使用查询而不是在变量文件中传递订阅 ID 来获取订阅 ID。有没有terraform的quickstart模板站点可以参考

Error: **Can not parse "scopes.0" as a resource id: Cannot parse Azure ID: parse "{subscription_id is getting printed here}":** invalid URI for request**

  on metric.tf line 1, in resource "azurerm_monitor_metric_alert" "example":
   1: resource "azurerm_monitor_metric_alert" "example" {

terraform.tf 文件

resource "azurerm_monitor_metric_alert" "example" {
  name                = "example-metricalert"
  resource_group_name = "MyTemp"
  scopes              = ["${var.subscription_id}"]
  description         = "Action will be triggered when Transactions count is greater than 50."
  target_resource_type = "Microsoft.Compute/virtualMachines"
  
  criteria { 
    metric_namespace = "Microsoft.Compute/virtualMachines"
    metric_name      = "Percentage CPU"
    aggregation      = "Total"
    operator         = "GreaterThan"
    threshold        = 50
  }

  action {
    action_group_id = "/subscriptions/xxxxxxxx/resourceGroups/xxxxx/providers/Microsoft.Insights/actionGroups/xxxxx"
  }
}

您可以使用 Data Source: azurerm_subscription 访问有关现有订阅的信息。

terraform.tf 文件将如下所示：

data "azurerm_subscription" "current" {

  subscription_id  = var.subscription_id
}

resource "azurerm_monitor_metric_alert" "example" {
  name                = "example-metricalert"
  resource_group_name = "MyTemp"
  scopes              = [data.azurerm_subscription.current.id]
  description         = "Action will be triggered when Transactions count is greater than 50."
  target_resource_type = "Microsoft.Compute/virtualMachines"
  
  criteria { 
    metric_namespace = "Microsoft.Compute/virtualMachines"
    metric_name      = "Percentage CPU"
    aggregation      = "Total"
    operator         = "GreaterThan"
    threshold        = 50
  }

  action {
    action_group_id = "/subscriptions/xxxxxxxx/resourceGroups/xxxxx/providers/Microsoft.Insights/actionGroups/xxxxx"
  }
}
