无法使用Get-AzureRmMetric访问[来宾]指标 [英] Unable to Access [Guest] metrics using Get-AzureRmMetric

问题描述

我为Azure虚拟机启用了访客级指标，并正在尝试使用Get-AzureRMMetric获取 [来宾] \ Memory \ Committed Bytes 属性的历史记录.

I have guest-level metrics enable for an Azure Virtual Machine and am trying to get the history for the [Guest]\Memory\Committed Bytes property using Get-AzureRMMetric.

$endTime = Get-Date
$startTime = $endTime.AddMinutes(-540)
$timeGrain = '00:05:00'
$metricName = '\Memory\Committed Bytes'


$history=(Get-AzureRmMetric -ResourceId $resourceId `
-TimeGrain $timeGrain -StartTime $startTime `
-EndTime $endTime `
-MetricNames $metricName)

$history.data | Format-table -wrap Average,Timestamp,Maxiumim,Minimum,Total

我收到以下错误:

如果我将$metricname更改为任何主机指标(例如，"CPU百分比")，此代码都可以正常工作，但是我需要获取内存信息.

This code works fine if I change the $metricname to any of the host metrics ("Percentage CPU" for example), but I need to get the memory information.

注意:这是在PowerShell 5.1中，我发现我可以在PowerShell v3中使用几乎相同的代码($history.metricvalues而不是$history.data)，并且可以进入 [来宾] 指标，但没有任何主机指标.

Note: This is in PowerShell 5.1, I've found that I can use almost the same code ($history.metricvalues rather than $history.data) in PowerShell v3 and I can get to the [Guest] metrics there, but not any of the host metrics.

推荐答案

目前，Azure PowerShell不支持不使用Get-AzureRmMetric获取memory usage指标.

For now, Azure PowerShell does not support to use Get-AzureRmMetric to get memory usage metrics.

我们可以使用Get-AzureRmMetricDefinition获取受支持的指标:

We can use Get-AzureRmMetricDefinition to get the supported metrics:

以下是Azure VM的指标:

Here are the metrics for Azure VM:

PS D:\testdata> (Get-AzureRmMetricDefinition -ResourceId $id).name

Value                     LocalizedValue
-----                     --------------
Percentage CPU            Percentage CPU
Network In                Network In
Network Out               Network Out
Disk Read Bytes           Disk Read Bytes
Disk Write Bytes          Disk Write Bytes
Disk Read Operations/Sec  Disk Read Operations/Sec
Disk Write Operations/Sec Disk Write Operations/Sec
CPU Credits Remaining     CPU Credits Remaining
CPU Credits Consumed      CPU Credits Consumed

关于Azure VM的支持指标，请参考此官方文章.

About supported metrics of Azure VM, please refer to this official article.

然后我们可以使用该值获取其他指标:

Then we can use the value to get other metrics:

Get-AzureRmMetric -ResourceId $id -TimeGrain 00:01:00 -DetailedOutput -MetricNames "Network in"

这是我的PowerShell输出:

Here is my PowerShell output:

作为一种解决方法，我们可以使用OMS获取内存使用情况，有关在OMS上配置性能计数器的更多信息，请参考此

As a workaround, we can use OMS to get the Memory usage, more information about configuring performance counters on OMS, please refer to this link.

更新:

您是对的，我们可以在Azure PowerShell版本3.4.0上运行此命令，效果很好.

You are right, we can run this command on Azure PowerShell version 3.4.0, it works fine.

在版本3.4.0上运行此命令时，将收到以下警告:

When we run this command on Version 3.4.0, we will get this warning:

警告:不赞成使用API​​:将使用传统指标API 在下一个版本中不再提供.这意味着通话发生了变化 以及此cmdlet的输出. 这是PowerShell的输出:

WARNING: API deprecation: The use of the legacy metrics API will be discontinued in the next release. This implies a change in the call and the output of this cmdlet. Here is the PowerShell output:

作为一种解决方法，我们可以通过REST API导出指标，有关它的更多信息，请参考此

As a workaround, we can via the REST API to export metrics, more information about it, please refer to this link.
