Syntax for obtaining snap delta change rate on all volumes on a 7-mode?

rtriana

Hi Communities, 

 

I am not a programmer ... and do not really have programming skills.   However, I am reaching out to communities because we need the syntax to get the change rate of all volumes on a 7-mode controller pair.    What would be the "for each" syntax so that we can run one command and get all the snap deltas for all the volumes in the HA pair?

 

get-nasnapshotdelta command ..

 

Thank you communities for your help.

Hello Rick,

 

The following script ought to do the trick.

 

$vols = Get-NaVol
Write-Host "Volume`tSnapshot`tConsumedSize`tElapsedTime"
foreach ($vol in $vols) {
	$snaps = Get-NaSnapshot $vol
	foreach ($snap in $snaps) {
		$res = Get-NaSnapshotDelta -TargetName $vol -SnapName1 $snap
		Write-Host $vol `t $snap `t $res.ConsumedSize `t $res.ElapsedTimeTS
	}
}

The output of the script would be

 

PS C:\Users\aparajir> & '..\SnapshotDelta.ps1'
Volume  Snapshot        ConsumedSize    ElapsedTime
