如何在 Azure 上的 VMSS AutoScale 规则中使用自定义 App Insight 指标？

Question

我正在尝试使用命令为我的虚拟机创建缩放规则

az monitor autoscale rule create --resource-group MyGroup --resource "cc-insight" --resource-type "Microsoft.Insights/components" --autoscale-name autoscale --condition "cc-response-time-view > 2000 avg 5m" --scale out 1

但得到

Exception of type 'Microsoft.WindowsAzure.Management.Monitoring.MonitoringServiceException' was thrown.. [Code: "UnsupportedMetric"]

虽然可以通过 App Insights 访问指标

经过一些手动测试，我解决了这个问题。

以下是 Terraform 的自定义指标规则配置。请记住，所有自定义指标名称均以“customMetrics/您的指标名称”

rule {
      metric_trigger {
        metric_name        = "customMetrics/cc-response-time-view"
        metric_resource_id = azurerm_application_insights.insight.id
        time_grain         = "PT1M"
        statistic          = "Average"
        time_window        = "PT5M"
        time_aggregation   = "Average"
        operator           = "LessThan"
        threshold          = 1500
      }

      scale_action {
        direction = "Decrease"
        type      = "ChangeCount"
        value     = "1"
        cooldown  = "PT1M"
      }
    }

对于使用控制台的用户，请不要忘记将命名空间设置为“microsoft.insights/组件/kusto”
