You can use the Get-Stat cmdlet with the Realtime switch, but be aware that the values returned are averages over a 20 second interval.
Something like this
$esxName = 'MyEsx'
$esx = Get-VMHost -Name $esxName
Get-VirtualSwitch -VMHost $esx -Standard -PipelineVariable vss |
ForEach-Object -Process {
$pnic = (Get-VMHostNetworkAdapter -VMHost $esx -VirtualSwitch $vss).Name
Get-Stat -Entity $esx -Stat 'net.transmitted.average', 'net.received.average' -Realtime -MaxSamples 1 |
Where-Object { $_.Instance -in $pnic } |
Group-Object -Property Instance |
ForEach-Object -Process {
New-Object -TypeName PSObject -Property ([ordered]@{
VMHost = $esx.Name
VSS = $vss.Name
PNic = $_.Name
ReceivedKBps = $_.Group.Where{ $_.MetricId -eq 'net.received.average' }.Value
TransmittedKBps = $_.Group.Where{ $_.MetricId -eq 'net.transmitted.average' }.Value
})
}
}
You can also use the Get-EsxTop cmdlet, which will give you values over a 5 second interval, similar to what esxtop is showing.
$esxName = 'MyEsx'
$esx = Get-VMHost -Name $esxName
Get-VirtualSwitch -VMHost $esx -Standard -PipelineVariable vss |
ForEach-Object -Process {
$pnic = (Get-VMHostNetworkAdapter -VMHost $esx -VirtualSwitch $vss -Server esx1.local.lab).Name
$ports = (Get-EsxTop -CounterName PNIC -Server esx1.local.lab | where{$_.PNICName -in $pnic}).UplinkPort
Get-EsxTop -CounterName NetPort -Server esx1.local.lab | where{$_.PortId -in $ports} |
ForEach-Object -Process {
New-Object -TypeName PSObject -Property ([ordered]@{
VMHost = $esx.Name
VSS = $vss.Name
PNic = $_.ClientName
ReceivedMBps = [math]::Round($_.NumOfRecvBytes/1MB/5,0)
TransmittedMBps = [math]::Round($_.NumOfSendBytes / 1MB/5, 0)
})
}
}
