Get snapshot status from CLI

[jakemike]

Hey guys, is there a way to get the current status of a snapshot? Similar to how the GUI shows a percentage.


I'm using the -runasync command to kick off a bunch of snapshots but would like to be able to query them and see what they're up to.


 


Thanks.

When you use the Get-Task cmdlet, the returned Task object has a property called PercentComplete.

Something like this

$task = Get-vm MyVM | Get-Snapshot | Remove-Snapshot -Confirm:$false -RunAsync

while ($Task.State -eq 'Running'){

    $task = Get-Task -Id $task.Id

    $task | Select State,PercentComplete

}

Hi LucD, thanks for that. My PS skills are pretty weak and although I managed to use your code to create and monitor a snapshot, I'm not sure how I could do that for multiples?

At the moment, I'm importing a CSV which contains a list of VMs to snapshot.

Fairly simple stuff:

$vms2snap=import-csv c:\temp\test_snapshot1.csv

foreach ($machine in $vms2snap) {

$vm_to_snap = $($machine.'computer')

get-vm -name $vm_to_snap | new-snapshot -name snaptest -Memory -RunAsync

}

Do you know how I could then go through and check the status of the snapshots? Just not sure how to incorporate your code into it.

Thanks.

Try something like this.

It first starts all the snapshots in background mode, and then in a loop, checks every 5 seconds for the status of the snapshots.

$taskTab = @{}

$vms2snap = Import-Csv c:\temp\test_snapshot1.csv -UseCulture | Select -ExpandProperty Computer

foreach ($machine in $vms2snap) {

    $task = Get-VM -Name $machine | New-Snapshot -Name snaptest -Memory -RunAsync

    $taskTab.Add($task.Id,$machine)

}

while($taskTab.Count -ne 0){

    $keys = @()

    $taskTab.GetEnumerator() | %{

        $newState = Get-Task -Id $_.Key

        if($newState.State -eq 'Running'){

            Write-Output "$($_.Value) - At $($newState.PercentComplete)%"

        }

        else{

            Write-Output "$($_.Value) Finished - $($newState.State)"

            $keys += $_.Key

        }

    }

    $keys | %{

        $taskTab.Remove($_)

    }

    sleep 5

}
