Hi,

I am unable to get the performance details for a VM as getting the below error

$servers=Get-Content ".\servers.txt"

foreach ($server in $servers)

{

    $vm=Get-VM $server

    if($? -eq $false)

    {

        continue

    }

    $fileName=".\$server.csv"

    $diskusageaverage=Get-Stat -entity $vm -MaxSamples 168 -Start (Get-Date).AddDays(-1) -IntervalMins 60 -stat "disk.usage.average" | ? { $_.instance -eq "" } | select Entity,Timestamp,Value |Sort-Object Timestamp

    $memusageaverage=Get-Stat -entity $vm -MaxSamples 168 -Start (Get-Date).AddDays(-1) -IntervalMins 60 -stat "mem.usage.average" | ? { $_.instance -eq "" } | select Entity,Timestamp,Value |Sort-Object Timestamp

    $cpuusageaverage=Get-Stat -entity $vm -MaxSamples 168 -Start (Get-Date).AddDays(-1) -IntervalMins 60 -stat "cpu.usage.average" | ? { $_.instance -eq "" } | select Entity,Timestamp,Value |Sort-Object Timestamp

    Set-Content -Value "ServerName,AVG_CPU_Time,AVG_CPU,AVG_MEM,AVG_disk,AVG_Net" -Path $fileName

    $diskus=0

    for ($i=0;$i -lt $cpuusageaverage.Count ; $i++)

    {

        if (($diskus -lt $diskusageaverage.count) -and ($cpuusageaverage[$i].Timestamp -eq $diskusageaverage[$diskus].Timestamp))

        {

            Add-Content -Value "$($cpuusageaverage[$i].Entity.Name),$($cpuusageaverage[$i].Timestamp),$($cpuusageaverage[$i].Value),$($memusageaverage[$i].Value),$($diskusageaverage[$diskus].Value),$($netusageaverage[$i].value)" -Path $fileName

            $diskus++

        }

        else

        {
