JGPSHNTAP, I'm with you on that, all my reporting is done using powershell now. Extremely valuable.
George, to get you started, below is a quick example of how to get your last transfer size using powershell. This will work assuming your snapmirrors are updated daily. In the event you have an hourly update schedule, things get a little tougher to handle but can be accomplished using scheduled snapshots on the volumes along with a little math and date comparisons.
Import-Module dataontap
Connect-NaController DESTINATIONCONTROLLER
$toEmail = ""
$vol=DESTINATIONVOLUME #at this point, you can also create a loop to run through all your destination volumes if you have a larger pool of snapmirrors
$toEmail = $toEmail + $vol + " - " (get-nasnapmirror $vol).LastTransferSize + "`n" #This command will write the name of the volume along with the last transfer size in bytes, feel free to do some math to this number to make it more readable
Once you have completed building your $toEmail variable with all the volumes you would like to measure, you can send an email off using send-mailmessage like below:
Send-MailMessage -From "ALIASEMAILADDRESS@DOMAIN.COM" -To "RECIPIENT@DOMAIN.COM -subject "Daily Snapmirror replication size report" -body $toEmail -smtpServer IP_ADDRESS_OF_SMTPSERVER
