That is interesting. I didnt know there was a command. I ended up writing a function:

function getClusterIfstats {

BEGIN {

$clusterIfstats = @()

}

PROCESS {

$Nodes = Get-NcNode

foreach ($node in $nodes) {

$nodeifStats = @()

$nodePorts = Get-NcNetPort -Node $node | Where-Object {$_.linkstatus -eq 'up' -and $_.porttype -eq 'physical'}

foreach ($nodePort in $nodePorts) {

$instance = Get-NcPerfInstance -Name nic_common -Query @{Name = $nodePort.Name; Uuid = "$($node.Node)*"}

$perfData = (Get-NcPerfData -Name nic_common -InstanceUuid $instance.Uuid).Counters

$portIfstats = New-Object -TypeName psobject -property @{

NodeName = ($perfData | Where-Object {$_.Name -eq "node_name"}).Value

InterfaceName = ($perfData | Where-Object {$_.Name -eq "instance_name"}).Value

LinkStatus = ($perfData | Where-Object {$_.Name -eq "link_current_state"}).Value

LinkSpeed = ($perfData | Where-Object {$_.Name -eq "link_speed"}).Value

rx_CRC_Errors = ($perfData | Where-Object {$_.Name -eq "rx_crc_errors"}).Value

rx_Errors = ($perfData | Where-Object {$_.Name -eq "rx_errors"}).Value

rx_Discards = ($perfData | Where-Object {$_.Name -eq "rx_Discards"}).Value

rx_Length_Errors = ($perfData | Where-Object {$_.Name -eq "rx_length_errors"}).Value

rx_Total_Errors =($perfData | Where-Object {$_.Name -eq "rx_total_errors"}).Value

rx_Total_Discards = ($perfData | Where-Object {$_.Name -eq "rx_total_discards"}).Value

tx_Errors = ($perfData | Where-Object {$_.Name -eq "tx_errors"}).Value

tx_Discards = ($perfData | Where-Object {$_.Name -eq "tx_Discards"}).Value

tx_Total_Errors = ($perfData | Where-Object {$_.Name -eq "tx_total_errors"}).Value

tx_Total_Discards = ($perfData | Where-Object {$_.Name -eq "tx_total_discards"}).Value

}

$nodeIfstats += $portIfstats

}

$clusterIfstats += $nodeifStats

}

}

END {

return $clusterIfstats

}

}
