Email Alert for Old Snapshots

Post by jeremystw » Mar 12, 2010 11:47 pm

Hello all. As part of our replication process we thought it would be helpful to monitor the age of snapshots to make sure that we do not have any snapshots older then 2 hours. To do this I used Vmware's Powershell add on "PowerCli" along with a sheduled task. I thought I would be a nice guy and share this script as it has been extremel helpful for us.

You just need to copy the below code into a file, change the variables, name it with a .ps1 extension and then create a scheduled task that launches the script. For Powershell n00bs you will need to change your powershell execution policy or sign the script. You can find out how to do this by typing get-help set-executionpolicy in powershell.

Here are the variables you will need to change to have this work in your environment
esxservername=change to your ESXserver or VC host name
user=vc or esx host user credentials
vmname=virtual machine name
.Addhours(-2)= this can be changed to any amount of time you like you can even change this to Add Days
fromaddress@example.com= from address
toaddress@company=address you would like to receive this alert
mail.company.com= your mail server


You can also change this to cover all of your VMs at once. If you need more info on doing this just let me know. Enjoy :P

Code: Select all

add-pssnapin VMware.VimAutomation.Core
connect-viserver esxservername or -user root -password password
$snapage=get-snapshot -VM vmname|where {$_.created -lt (get-date).Addhours(-2)}|select created, powerstate,vm, name
if ($snapage -eq $Null){write-output "snapgood";exit 0}
else {Write-output "A Snapshot exist that is over 2 hours old"}
$emailFrom = "fromaddress@company.com"
$emailTo = "toaddress@company"
$subject = "!!A Snapshot is over 2 hours old!!"
$body = "-------Please check the Replication job for any issues----$snapage"
$smtpServer = "mail.company.com"
$smtp = new-object Net.Mail.SmtpClient($smtpServer)
$smtp.Send($emailFrom, $emailTo, $subject, $body)
