    while(1){
Get-WmiObject -class Win32_PerfFormattedData_Tcpip_NetworkInterface |select name , BytesTotalPersec | Out-File -FilePath "c:\vm\value.txt" 
$out = Get-Content -Path "C:\temp\vm\value.txt"
}
$out | Out-GridView
    I am trying to display the out value in real time in a popup. Above mentioned code doesn't bring any error , but I believe it is stuck in loop. It doesn't display the Grid popup with output. Any ideas would be appreciated!

    & {
      while(1){
        Get-WmiObject Win32_PerfFormattedData_Tcpip_NetworkInterface |
        select name, BytesTotalPersec
        sleep 1
      } 
    } | out-gridview

    While doesn't stream, but a scriptblock with a call operator does (or a function).

    What do you mean by "real time".  PowerShell is not a "real time" system.

    Do you mean you want to open in the pipeline?

    This is as close as you will get.

    1..100 | ForEach-Object {
        Get-WmiObject Win32_PerfFormattedData_Tcpip_NetworkInterface
    } |
    Select-Object name, BytesTotalPersec | 
    Out-GridView

    You can do this in the console:

    get-content -wait C:\temp\vm\value.txt

    If you use Get-Counter it can display at defined intervals. There are also other system utilities that can track network TX/RX numbers ina GUI.

    "PerfMon" is about the best diagnostic and performance monitoring tool available on WIndows.

    At any prompt type "perfmon" and select the menu item "Perfomance Monitoring". 

    This is a GUI that display exactly what you are trying to display and it is updated dynamically on any interval you choose.

    See this for complete instructions from MS, https://techcommunity.microsoft.com/t5/Ask-The-Performance-Team/Windows-Performance-Monitor-Overview/ba-p/375481

    How about this?

    While ($true){
    Get-WmiObject -class Win32_PerfFormattedData_Tcpip_NetworkInterface |select name , BytesTotalPersec | 
        convertto-html -Head '<title>HTML TABLE</title><META HTTP-EQUIV="refresh" CONTENT="1">'| 
            Out-File c:\temp\test.html
         Sleep 0.9 # or whatever you think is appropriate -- or just omit it altogether
}

    Launch a browser and open the HTML file. It'll refresh once every second.
