Get-Snapshot missed snapshot for 4 days

[sjesse]

Any idea why the below code wouldn't report a snapshot for a few days

Get-VM | Get-Snapshot | Where {$_.Created -lt (Get-Date).AddDays(-4)} | Select-Object VM, Description, Created

basically, I count the results,  and if its zero I send an email saying there is none, and if there are some I send a table with some. I have a snapshot that was created May 4, but wasn't reported till May 12, which is much more than the 4 days. I went through the events of the vm and I don't see any restores, I can see when the snapshot was taken and when they were deleted, but no explanation of why I didn't know till much later than I like.

That line looks perfectly ok to report snapshots older than 4 days.

Could it be something went wrong in the further handling of the result?
Or the email could perhaps have ended up in a Spam/Junk folder?

I've been getting an email every day, just not one with snapshots. I count the size array and if its less then 1 I get an email saying no snapshots found. The email I got on the 12th did have valid snapshots listed,plus these extra snapshots should have been related.

I would need to see the code where you test and send the email to further analyse.

Is this running through a Scheduled Task?
Does the Scheduled Task history confirm that it ran every day? Without error?
You could also have a look at the smtp log on your mail server.

I tried to keep it as close as possible with removing things.

$vcUser=""

$vcPassword=""

Connect-VIServer vcenter.fqdn -User $vcUser -Password $vcPassword

$smtpServer = smtp.fqdn

$smtpFrom = "noreply@fqdn"

$smtpTo = @(list of emails)

$smtpToTest = @("list of emails")

$style = "<style>BODY{font-family: Arial; font-size: 10pt;}"

$style = $style + "TABLE{border: 1px solid black; border-collapse: collapse;}"

$style = $style + "TH{border: 1px solid black; background: #dddddd; padding: 5px; }"

$style = $style + "TD{border: 1px solid black; padding: 5px; }"

$style = $style + "</style>"

$messageSubject = "Snapshots over 72 hours old"

$pdc_vms = Get-VM | Get-Snapshot | Where {$_.Created -lt (Get-Date).AddDays(-4)} | Select-Object VM, Description, Created

Disconnect-VIServer vcenter.fqdn -Force -Confirm:$false

Connect-VIServer vcenter2.fqdn -User $vcUser -Password $vcPassword

$sdc_vms= Get-VM | Get-Snapshot | Where {$_.Created -lt (Get-Date).AddDays(-4)} | Select-Object VM, Description, Created

Disconnect-VIServer vcenter2.fqdn -Force -Confirm:$false

$vms=$pdc_vms + $sdc_vms

if($vms.Count -gt 0)

{

    $messageBody=$vms | ConvertTo-Html -Head $style | Out-String

}else{

    $messageBody="No Snapshots Found"

}

Send-MailMessage -From $smtpFrom -To $smtpTo -Subject $messageSubject -BodyAsHtml $messageBody -SmtpServer $smtpServer

Ok, you did get the mail with the "No Snapshots Found" entry then?

Yeah that's what is wierd, the job is running and I'm getting the email, just for some reason at that time either I couldn't see any snapshots at all or the two that showed up later where hidden for some reason. I'm thinking of doing some error handling on get-vm possiblly checking to see if it can find the actual vcenter vm and report an error if get-vm doesn't return anything.
