Re: [Script / Code sample Request] Get Total Network throughput for given set of ESXi hosts or pNICs

Try it like this

$esx=Get-VMHost
$stat="net.received.average","net.transmitted.average"
$start= (Get-Date).AddMinutes(-30)

Get-Stat-Entity$esx-Stat$stat-Start$start-Realtime|
Group-Object-Property {$_.Entity.Name} |%{
  $record=New-ObjectPSObject-Property@{
    CollectionTime=$_.Group[0].Timestamp
    Host=  $_.Name
  }
  $_.Group|where {$_.Instance-match"vmnic"} |
    Group-Object-PropertyInstance|%{
    $RxValue=$_.group|where {$_.MetricId-eq"net.received.average"} |
      Measure-Object-PropertyValue-Average-Maximum
    $TxValue=$_.group|where {$_.MetricId-eq"net.transmitted.average"} |
      Measure-Object-PropertyValue-Average-Maximum
    Add-Member-InputObject$record-Name ($_.Name+"AvgRx (KBps)") -Value ([math]::Round($RxValue.Average,1)) -MemberTypeNoteProperty
    Add-Member-InputObject$record-Name ($_.Name+"AvgTx (KBps)") -Value ([math]::Round($TxValue.Average,1)) -MemberTypeNoteProperty
    Add-Member-InputObject$record-Name ($_.Name+"MaxRx (KBps)") -Value ([math]::Round($RxValue.Maximum,1)) -MemberTypeNoteProperty
    Add-Member-InputObject$record-Name ($_.Name+"MaxTx (KBps)") -Value ([math]::Round($RxValue.Maximum,1)) -MemberTypeNoteProperty
  }
  $record
}
