The statistics for the last day are already aggregated for a 5-minute interval.
That would make it hard to get values for a 1-minute interval.
The following will give you the value (ms and percentage) over the 5-minute interval.
$clusterName = 'MyCluster'
$interval = 5
$stat = 'cpu.ready.summation'
$finish = Get-Date
$start = ($finish).AddHours(- $interval)
$entity = Get-Cluster -Name $clusterName | Get-VM
Get-Stat -Entity $entity -Stat $stat -Start $start -Finish $finish |
Group-Object -Property {$_.Entity.Name} | %{
$_.Group | %{
New-Object PSObject -Property @{
VM = $_.Entity.Name
Date = $_.Timestamp
ReadyMs = $_.Value
ReadyPerc = "{0:P2}" -f ($_.Value/($_.Intervalsecs*1000))
}
}
}
