在 Azure 中使用 Terraform 为应用服务创建自动缩放规则时出错

Question

resource "azurerm_monitor_autoscale_setting" "test" {
  name                = "AutoscaleSetting"
  resource_group_name = "${azurerm_resource_group.main.name}"

  target_resource_id  = "${azurerm_app_service_plan.main.id}"

 profile {

capacity {
  default = 1
  minimum = 1
  maximum = 10

rule {

    metric_name        = "Percentage CPU"

我尝试在 terraform on azure 中设置自动缩放规则。这样做时它抛出了这个错误。请帮忙解决这个问题。这是什么错误，如何解决？

Error : Error creating AutoScale Setting "AutoscaleSetting" (Resource Group "sm-prod-resources"): insights.AutoscaleSettingsClient#CreateOrUpdate: Failure responding to request: StatusCode=400 -- Original Error: autorest/azure: Service returned an error. Status=400 Code="UnsupportedMetric" Message="Exception of type 'Microsoft.WindowsAzure.Management.Monitoring.MonitoringServiceException' was thrown."

Answer 1

错误表明它是一个 UnsupportedMetric。根据Terraform中的文档，是这样描述的：

metric_name - (Required) The name of the metric that defines what the rule monitors, such as Percentage CPU for Virtual Machine Scale Sets and CpuPercentage for App Service Plan.

我认为这只是你犯的一个错误，带有“Percentage CPU”的名称是虚拟机规模集的名称，你需要将其更改为“CpuPercentage "，这是你想要的应用程序服务计划。有关详细信息，请参阅 metric_name。
