尝试访问应用服务计划指标时，Get-AzMetric 命令返回错误

Question

这是我的代码： 我检查权限是否正确并检查文档，但我没有找到答案。

$metricParams = @{
    ResourceId = "/subscriptions/$($subscriptionId)/resourceGroups/$($resourceGroup)/providers/Microsoft.Web/serverfarms/$($appServicePlanName)/Metrics"
    MetricName = "CPU Percentage"
    Aggregation = "Average"
    StartTime = (Get-Date).AddHours(-1)  # Inicio de la consulta, por ejemplo, para la última hora
    EndTime = Get-Date  # Fin de la consulta
}

Exception type: ErrorResponseException, Message: Microsoft.Azure.Management.Monitor.Models.ErrorResponseException: Operation returned an invalid status code 'NotFound'

Answer 1

根据这个Document，

Get-AzMetric

命令使用

microsoft.web/sites

资源类型和资源id来获取指标这是Azure Web应用程序的指标并且Azure Web应用程序不包含CPU百分比指标。 CPU 百分比指标包含在应用服务计划中。 对于 Azure 应用程序服务计划指标，您需要参考此 Document2，它使用

Get-AzAppServicePlanMetrics

命令来获取应用程序服务计划的 CPU 百分比指标：-

首先获取资源类型为 microsoft.web/sites 的资源 ID，以便在命令中使用它，如下所示：-

Get-AzResource -ResourceGroupName siliconrg -ResourceType Microsoft.web/sites

输出：-

在 Get-AzMetrics 命令中使用此 ResourceID，如下所示：-

Get-AzMetric -ResourceId "/subscriptions/sub-id/resourceGroups/siliconrg/providers/Microsoft.Web/sites/siliconwebapp096" -TimeGrain 00:01:00 

输出：-

为了获取应用服务计划 CPU 百分比，请参阅此脚本 Document2：-

$currentTime = Get-Date -UFormat "%Y-%m-%dT%H:%M:%SZ"


$endTime = $currentTime

$startTime = (Get-Date).AddHours(-1)


$startTimeFormatted = $startTime.ToUniversalTime().ToString("yyyy-MM-ddTHH:mm:ssZ")


Write-Host "UTC Start Time: $startTimeFormatted"
Write-Host "UTC End Time: $endTime"

Get-AzAppServicePlanMetrics -ResourceGroupName "Resource-group-name" -Name "Appservice-plan-name" -StartTime 2023-09-23T07:21:06Z -EndTime 2023-09-23T13:51:06Z -Granularity PT1M -Metrics ["CPU Percentage"] -Debug
