Re: Problem with get-stat command and scripting

Ok, I think I see what you want.

Try this version

$midnight=Get-Date-Hour0-Minute0-Second0
$metrics_rp="cpu.usagemhz.average","cpu.usagemhz.maximum"
$rp=Get-Cluster-NameITSDEV|Get-ResourcePool

Get-Stat-Entity$rp-Stat$metrics_rp-Start$midnight.adddays(-1).addminutes(-1) -Finish$midnight.addminutes(-1) |
Group-Object-Property {$_.EntityId} |%{
  $cluster=&{
    $parent=$_.Group[0].Entity.Parent
    while ($parent-and$parent.ExtensionData-isnot [VMware.Vim.ClusterComputeResource]){
      $parent=$parent.Parent
    }
    $parent
  }
  $hourAvg=@()
  $hourMax=@()

  $_.Group|Group-Object-Property {$_.Timestamp.Hour} |%{
    $hourAvg+=$_.Group|Where {$_.MetricId-eq"cpu.usagemhz.average"} |
    Measure-Object-PropertyValue-Average|Select-ExpandPropertyAverage
    $hourMax=$_.Group|Where {$_.MetricId-eq"cpu.usagemhz.maximum"} |
    Measure-Object-PropertyValue-Maximum|Select-ExpandPropertyMaximum
  }
  $report=@()
  $row=""|Select"Interval Start","Resource Pool",Cluster,"CPU MHz Avg","CPU MHz Max"
  $row."Interval Start"=$_.Group|Sort-Object-PropertyTimestamp|
  Select-First1|Select-ExpandPropertyTimestamp
  $row.Cluster=$cluster.Name
  $row."Resource Pool"=$_.Group[0].Entity.Name
  $row."CPU MHz Avg"=$hourAvg|Measure-Object-Average|
    Select-ExpandPropertyAverage
  $row."CPU MHz Max"=$hourMax|  Measure-Object-Maximum|
    Select-ExpandPropertyMaximum
  $report+=$row
  $report|Export-CsvC:\$($cluster.Name)-$($_.Group[0].Entity.Name)_stats.csv
}

Note that there will be 1 CSV file per resourcepool. Is that what you want ?
