Export-csv only generating the output only for single server

Question

Hi Team,
From the below script I'm unable to generate the single output file for all the condition. The script only giving the last server output, It's skipping the all the other servers in the file.
$ScriptBlock = {
    param
        $Server,
        $ExportCSV
$Counters= import-csv "G:\testcounter.csv"
foreach($Counter in $Counters)
$ObjectName=$Counter.ObjectName
$CounterName=$Counter.CounterName
$InstanceName=$Counter.InstanceName
$Result=Get-Counter -Counter "\\$server\$ObjectName($InstanceName)\$CounterName"
    $CounterSamples = $Result | % {$_.CounterSamples}
    $MasterArray = @()
    foreach ($CounterSample in $CounterSamples)
        $TempArray = @()
        $TempArray = "" | Select Server, ObjectName, CounterName, InstanceName, SampleValue, DateTime
        $Split = $CounterSample.Path.Remove(0,2)
        $Split = $Split.Split("\")
        $TempArray.Server = $Split[0]
        $TempArray.ObjectName = $Split[1].Split("(")[0]
        $TempArray.CounterName = $Split[2]
        $TempArray.InstanceName = $CounterSample.InstanceName
        $TempArray.SampleValue = $CounterSample.CookedValue
        $TempArray.DateTime = $CounterSample.TimeStamp.ToString("yyyy-MM-dd HH:mm:ss")
        $MasterArray += $TempArray
    $MasterArray | Export-Csv $ExportCSV -NoType
$Servers = import-csv "G:\testcounter.csv"
foreach ($Server in $Servers)
    $server=$server.server
    If (Test-Connection -quiet -computer $server){
        $ExportCSV = "G:\PerformaneData.csv"
        Start-Job -ScriptBlock $ScriptBlock -ArgumentList @($server, $ExportCSV)

Hi RatheeshAV,
In addition, to export the result to csv file, please also try to wait for all the jobs to complete then retrieve all the data and write it to a file in one step:
$ScriptBlock = {
param ($Server)
#SCRIPT
$MasterArray }
$Servers = import-csv "G:\testcounter.csv"
Get-Job | Remove-Job
$jobs=@()
foreach ($Server in $Servers){
$server=$server.server
If(Test-Connection -quiet -computer $server){
Write-Host $Server -ForegroundColor green
$ExportCSV = "G:\PerformaneData.csv"
$job+=Start-Job -ScriptBlock $ScriptBlock -ArgumentList $server
$jobs | Wait-Job
$jobs | Receive-job | Export-CSV 'd:\temp.csv' -NoTypeInformation
Refer to:
PS3 Export-CSV -Append from
multiple instances to the same csv file
If there is anything else regarding this issue, please feel free to post back.
