Hi Hans and welcome to the Communities!
There is nothing obvious that springs to mind to do what you are looking for.
Two things though:
- I would try to figure out whether OS-level defragmentation has been run / is scheduled on any of these VMs
- Are you running deduplication on this volume? If snapshots growth is 'exceptional', then it may simply mean dedupe savings have been shifted into snapshots (http://communities.netapp.com/message/22012#22012)

Best I've been able to do is watch system monitors of the guests for high disk i/o - that tells me which one is changing blocks, which would then show as snaps. Make sure you're not snapping vswp as well (should be on a different volume) as that will inflate your snapshots also.

You may not be able to tell growth, but there is a tool that lets you see ALL the snapshots at once from the VM's so you can keep an eye on them..
This is easier by pointing it to a vCenter but it will work at the ESX host level.
