amazon-web-services - 对象列表的 AWS CloudWatchMetricStatistic

问题描述

我有一个 instanceId 列表，我想将其用作 get-cwmetricstatistic 的输入，以便输出汇总的 cloudwatch 指标列表。我有获取instanceIds 列表的代码，并且我有用于拉回单个instanceId 的摘要统计信息的代码。我正在努力在 foreach-object 中构建维度，以便正确传递 instanceID。请参阅下面的示例代码...

我知道这可以获取 InstanceIds：

$instances = Get-EC2Instance -AccessKey $AccessKey -Region us-east-1 -SecretKey $SecretKey -SessionToken $SessionToken | 
Select-Object -ExpandProperty Instances | 
Select-Object InstanceId

而且我知道这可以获取单个 instanceID 的摘要统计信息：

$dimension = New-Object Amazon.CloudWatch.Model.Dimension
$dimension.set_Name("InstanceId")
$dimension.set_Value("i-xxxxxxxxxxxxxx")

$data = Get-CWMetricStatistic -AccessKey $AccessKey -Dimension $dimension -MetricName CPUUtilization -Namespace AWS/EC2 -Period 86400 -Region us-east-1 -SecretKey $SecretKey -SessionToken $SessionToken -Statistic Average -UtcEndTime 2019-09-28T04:00:00Z -UtcStartTime 2019-09-22T04:00:00Z 
 foreach($datapoint in $data.Datapoints){
    Write-Host $dimension.Value $datapoint.Timestamp " " $datapoint.Average 
}

以下是尝试遍历不起作用的 instanceIds 列表的代码：

$instances = Get-EC2Instance -AccessKey $AccessKey -Region us-east-1 -SecretKey $SecretKey -SessionToken $SessionToken | 
Select-Object -ExpandProperty Instances | 
Select-Object InstanceId |

ForEach-Object  {
$dimension = New-Object Amazon.CloudWatch.Model.Dimension
$dimension.set_Name("InstanceId")
$dimension.set_Value($instanceId)

$data = Get-CWMetricStatistic -AccessKey $AccessKey -Dimension $dimension -MetricName CPUUtilization -Namespace AWS/EC2 -Period 86400 -Region us-east-1 -SecretKey $SecretKey -SessionToken $SessionToken -Statistic Average -UtcEndTime 2019-09-28T04:00:00Z -UtcStartTime 2019-09-22T04:00:00Z 
 foreach($datapoint in $data.Datapoints){
    Write-Host $dimension.Value $datapoint.Timestamp " " $datapoint.Average 
}
}

解决方案

解决方案：

$instances = Get-EC2Instance -AccessKey $AccessKey -Region us-east-1 -SecretKey $SecretKey -SessionToken $SessionToken | 
Select-Object -ExpandProperty Instances | 

ForEach-Object  {
$dimension = New-Object Amazon.CloudWatch.Model.Dimension
$dimension.Set_Name("InstanceId")
$dimension.Set_Value($_.InstanceId)

$data = Get-CWMetricStatistic -AccessKey $AccessKey -Dimension $dimension -MetricName CPUUtilization -Namespace AWS/EC2 -Period 86400 -Region us-east-1 -SecretKey $SecretKey -SessionToken $SessionToken -Statistic Average -UtcEndTime 2019-09-28T04:00:00Z -UtcStartTime 2019-09-20T04:00:00Z 

foreach($datapoint in $data.Datapoints){
    Write-Host $dimension.Value $datapoint.Timestamp "CPUUtilization-Average" $datapoint.Average
}
}
