Can you list the number of reverts per snapshot pe...

VM Name Snapshot Name Times Reverted (30 days)

vm001 Base install 4

Thanks.

I am not able to get the number of snapshot reverts per snapshot per vm. But I am able to get the number of snapshot reverts per virtual machine. I hope this will help a little.

Get-VIEvent -Start (Get-Date).AddDays(-30) -Types Info | `
Where-Object {$_.FullFormattedMessage -like "Task: Revert*"} | `
Select-Object -ExpandProperty Vm | `
Select-Object -Property Name | `
Group-Object -Property Name | `
Select-Object -Property Name,Count

Regards, Robert

The Where-Object line in the script changed because of Luc's remark about missing some events.

You can find the snapshot reverts in the TaskEvent entries.

But it looks as if these events do not contain the name of the snapshot to which the guest was reverted.

$report = @()

Get-VIEvent -Start (Get-Date).AddDays(-1) | `
    where {$_.GetType().Name -eq "TaskEvent" -and $_.FullFormattedMessage -like "Task: Revert*"} | %{
        $row = "" | Select VM,Date
        $row.VM = $_.Vm.Name
        $row.Date = $_.CreatedTime
        $report += $row}
$report

The message can also say "Task: Revert to current snapshot".

You will be missing those I'\m afraid.

This returned zero results, but I know that is not correct.

RvdNieuwendijk · ‎12-15-2010

It looks like you have put the line beginning with Get-VIEvent and the line beginning with Where on one line. Then you should remove the backquote `. The backquote is used to split a PowerShell command over two lines. If you revert it to one line the backquote should be removed.

The new forum SW seems to have swallowed a CR-LF.

I corrected the code, can you try again ?

The script is running now, but not sure if the data is accurate. This specific vCenter has over 700 VMs and running the script for the past 30 days resulted in two "reverts". Everyone has this access so I can't believe that is it.

I seriously doubt that you can find out the number of reverts in a reliable way other then inspecting ALL old vmware.logs of that VM.

Guessing by the usual naming convention or something like that would be very unreliable

Found the cause, the Get-VIEvent cmdlet even when you use it with the -Start parameter only returns 100 events.

If you add the -MaxSamples parameter with a huge number it will return all your reverts.

$report = @()

Get-VIEvent -Start (Get-Date).AddDays(-30) -MaxSamples 99999  | `
    where {$_.GetType().Name -eq "TaskEvent" -and $_.FullFormattedMessage -like "Task: Revert*"} | %{
        $row = "" | Select VM,Date
        $row.VM = $_.Vm.Name
        $row.Date = $_.CreatedTime
        $report += $row}
$report

Note that the script will run for a long time !

Then something is wrong because it came back in only a few minutes.

LucD · ‎12-15-2010

Did you get more than 2 reverts now ?

You can run the following, that way you are sure that you have at least events for each day.

Get-VIEvent -Start (Get-Date).AddDays(-30) -MaxSamples 99999 | `
    Group-Object -Property {$_.CreatedTime.Date}

And you can do the next script that will show how many Revert tasks you have per day

Get-VIEvent -Start (Get-Date).AddDays(-30) -MaxSamples 99999 | `
    where {$_.GetType().Name -eq "TaskEvent" -and $_.FullFormattedMessage -like "Task: Revert*"} | `
    Group-Object -Property {$_.CreatedTime.Date}

You can of course be running this on a super-fast vCenter 😉

1 - there are a lot more showing up here in the total counted that are not showing up from the original script.

2 - it only went back to 12/8.

Thanks.

1. There are more showing up in the 2nd script ? The one that filters on the eventtype and task name ?

2. My original post had AddDays(-7). That explains the timerange. Changed it to AddDays(-30).

Get-VIEvent -Start (Get-Date).AddDays(-30) -MaxSamples 99999 | where {$_.GetType().Name -eq "TaskEvent" -and $_.FullFormattedMessage -like "Task: Revert*"} | Group-Object -Property {$_.CreatedTime.Date}

results in...
