必须定义命名空间才能使用自定义指标

Question

我正在尝试为使用 Terraform 的 VM 部署内存指标，该指标属于 VM 的来宾指标，我已经为我正在使用的指标定义了命名空间，但它抛出了以下错误。

创建或更新指标警报“内存使用警报”时出错（资源组“MyTemp”）：insights.MetricAlertsClient#CreateOrUpdate：响应请求失败：StatusCode=400 -- 原始错误：autorest/azure : 服务返回错误。 Status=400 Code="BadRequest" Message="未找到以下指标名称：Memory\% Committed bytes 正在使用。 请注意，对于自定义指标，必须指定相关的指标命名空间。

resource "azurerm_monitor_metric_alert" "myalert" {
  name                      = "Memory Usage Alert"
  resource_group_name       = var.rg_name //resource name to which you want to deploy this alert
  scopes                    = [var.virtual_machine_id]
  description               = "Action will be triggered when Memory Utilzation count is greater than 85."
  target_resource_type      = "Microsoft.Compute/virtualMachines"
  target_resource_location  = "centralindia"
  frequency                 = "PT30M"
  window_size               = "P1D"
  severity                  = "2"
  enabled                   = "true"

  criteria {
    metric_namespace = "azure.vm.windows.guestmetrics"
    metric_name      = "Memory\% Committed bytes in use"
    aggregation      = "Average"
    operator         = "GreaterThanOrEqual"
    threshold        = 85
  }

  action {
    action_group_id = var.action_name
  }
}

关于这个问题，可以参考下面的脚本

使用 Azure 诊断 VM 扩展将 Azure 来宾 VM 指标发送到 Azure 监视器。详情请参考here and here

请注意，在运行脚本之前，您需要在您的 VM

中启用 Azure MSI 和 boot_diagnostics

创建指标警报

resource "azurerm_monitor_metric_alert" "myalert" {
  name                     = "myalert"
  resource_group_name      = var.resource_group_name
  scopes                   = [var.virtual_machine_id]
  description              = "Action will be triggered when Memory Utilzation count is greater than 85."
  severity                 = "2"
  enabled                  = "true"
  frequency                = "PT1M"
  window_size              = "PT5M",
  target_resource_type     = "Microsoft.Compute/virtualMachines"
  target_resource_location = "japaneast"

  criteria {
    metric_namespace = "azure.vm.windows.guestmetrics"
    metric_name       = "Memory\% Committed bytes in use"
    aggregation       = "Average"
    operator          = "GreaterThanOrEqual"
    threshold         = 85

   
  }

  action {
    action_group_id = var.action_group_name
  }
}

必须定义命名空间才能使用自定义指标

Namespace must be defined to use Custom Metrics
