Fast Snapshot Report

We needed a way to identify all machines that had snapshots.  Get-snapshot was far too slow, so I wrote this script to quickly generate a report of all VMs with snapshots more than 2 weeks old.  This script completes in 2.3 seconds when run against 400 VMs.  You will need to insert your own datacenter name.

$datacenter = "**datacenter name**"
$outputFile="snapreport.html"
$SnapReport = @()
Get-View -ViewType VirtualMachine -Property Name,Snapshot -SearchRoot(Get-Datacenter $datacenter | get-view).MoRef `

-Filter @{"Snapshot"="VMware.Vim.VirtualMachineSnapshotInfo"} | foreach-object {
    $vmname = $_.Name
    (Get-View -Id $_.MoRef -Property Snapshot).Snapshot.RootSnapshotList | foreach-object {
        If ($_.CreateTime -lt (get-date).adddays(-14)){
            $row = "" | Select-Object VirtualMachine, SnapshotName, SnapshotCreated
            $row.VirtualMachine = $vmname
            $row.SnapshotName = $_.Name
            $row.SnapshotCreated = $_.CreateTime
            $SnapReport += $row
        }
    }
}
