Snapshots report

[antoniogemelli]

Hello, I would like to run a script to get snapshots list (csv) with: Who created (user) When (date) Snapshot name and description, Host and VM name., Space in Gb or Mb, Datacenter/Cluster I use RvTools  but with this tool I can't get who created. Thanks

Have a look on this one Snapshot Management – Who done and When #PowerShell #VMware | CheckYourLogs.Net 

This should cover all your queries.

Please consider marking this answer "correct" or "helpful" if you think your query have been answered correctly.

Do you actually ever read a question completely?

And please, please stop begging for points :smileysad:

[vijayrana968]

I don't know what is the problem here. I read question and somewhere it's response relevant to the query. Someone will give point here only if his/her query has been answered or helpful.

Guys ,I really appreciate yours help, always I can see yours answers and I solved most of my tasks, please don't fight for me :-) vijayrana968 Snapshots Management is quite complex, I would like to run just a script if is possible to get that information's because I need just sometimes to check if there are very old snapshots where some colleague 'forgot' to consolidate/delete and maybe name and description are not clear to understand which change or task refer. Thanks :-)

I am beginner to scripting, don't know its in deep but I try to make some tweaks to get what I want. Goal to being here is gain and share knowledge, not for points.

I used below script, getting most of the things you need except VMHost. I am still checking this further.

$Report = Get-VM |

    Get-Snapshot |

    Select VM,

    Name,

    Description,

    @{Name="User"; Expression = { (Get-VIEvent -Entity $_.VM -Start $_.Created.AddSeconds(-10) | Where {$_.Info.DescriptionId -eq "VirtualMachine.createSnapshot"} | Sort-Object CreatedTime | Select-Object -First 1).UserName}},

    @{Name="SizeGB";Expression={ [math]::Round($_.SizeGB,2) }},

    Created,

    @{Name="Days Old";Expression={ (New-TimeSpan -End (Get-Date) -Start $_.Created).Days }} | Export-Csv C:\Reports\Snapshotreport.csv

The results are like this..

[jonathanmsa]

Function Get-SnapshotCreator {
    Param (
        [string]$VM,
        [datetime]$Created
    )
    (Get-VIEvent -Entity $VM -Types Info -Start $Created.AddSeconds(-10) -Finish $Created.AddSeconds(10) | Where-Object {$_.FullFormattedMessage  -eq 'Task: VirtualMachine.createSnapshot'} | Select -ExpandProperty UserName).Split("\")[-1]
}
$csv =  import-csv  <Location>
foreach($vm in $csv){
    Get-Cluster |Get-VM $vm | Get-Snapshot | select  VM,`
    @{Name="SnapShotName";Expression={ $_.Name}},
    @{Name="CreatedBy";Expression={ Get-SnapshotCreator -VM $_.VM -Created $_.Created }},
    PowerState,
    @{Name="SnapShot Description";Expression={ $_.Description}},  
    @{Name="SizeGB";Expression={ [math]::Round($_.SizeGB,2) }},
    Created,
    @{Name="Cluster";Expression={ Get-Cluster -VM $_.VM | select -ExpandProperty name }}
}

One more line can be added for hosts as anoton need Host infor as well.

@{Name="Host";Expression={ Get-VMHost -VM $_.VM | select -ExpandProperty name }},

Try like this.

You might want to play with 1 minute, before and after, interval in the Get-VIEvent cmdlet.

Depending how busy your vCenter is, there might be a bigger delta between the snapshot timestamp and the event.

Update: fixed an issue with double User names.

This would happen when a snapshot was taken, then deleted and a new snapshot taken, within the time span of 2 minutes

$clusterName = 'MyCluster' 

 

Get-Cluster -Name $clusterName | Get-VM | Get-Snapshot |

select  Name,

    Created,

    @{N='VM';E={$_.VM.Name}},

    @{N='VMHost';E={$_.VM.VMHost.Name}},

    @{N='Cluster';E={$_.VM.VMHost.Parent.Name}},

    @{N='Datacenter';E={

        $p = Get-View -Id $_.VM.VMHost.Parent.ExtensionData.Parent -Property Name,Parent

        while($p -and $p -isnot [VMware.Vim.Datacenter]){

            $p = Get-View -Id $p.Parent -Property Name,Parent

        }

        if($p){

            $p.Name

        }

    }},

    @{N='SizeMB';E={[math]::Round($_.SizeMB,1)}}, 

    @{N='SizeGB';E={[math]::Round($_.SizeGB,1)}},

    @{N='User';E={

        Get-VIEvent -Start $_.Created.AddMinutes(-1) -Finish $_.Created.AddMinutes(1) |

        where{$_ -is [VMware.Vim.TaskEvent] -and $_.Info.DescriptionId -eq 'VirtualMachine.createSnapshot'} |

        select -Last 1 -ExpandProperty UserName

    }} |

Export-Csv snap-report.csv -NoTypeInformation -UseCulture

Hi Luc,

is there anyway that this script could determine snapshot creator if it was awhile back? perhaps like 2-3 months old?

And how this script could call not just a single vcenter but many vcenters to look for snapshot?

Thanks.

[LucD]

If you keep the events in the vCenter for that long, the User field should show the creator of the snapshot.

You can connect to all vCenters, and then use a ForEach loop of all vCenters in $global:defaultVIServers.

And add the Server paramater on the other cmdlets.

This one work great, thank you for sharing!

[antoniogemelli]

Well, I using this one:

it gave me user ad execution is fast,

Get-Snapshot |

    Select VM,

    Name,

    Description,

    @{Name="User"; Expression = { (Get-VIEvent -Entity $_.VM -Start $_.Created.AddSeconds(-10) | Where {$_.Info.DescriptionId -eq "VirtualMachine.createSnapshot"} | Sort-Object CreatedTime | Select-Object -First 1).UserName}},

    @{Name="SizeGB";Expression={ [math]::Round($_.SizeGB,2) }},

    Created,

    @{Name="Days Old";Expression={ (New-TimeSpan -End (Get-Date) -Start $_.Created).Days }} | Export-Csv C:\Users\gemela\Desktop\Snapshotreport.csv

I will try others too and let you know.
