Big snapshots on a vmware LUN

Hello all,

 

Lately I'm facing a problem with a LUN containing virtual machines.

In fact, the volume contains the LUN (mapped to vmware eSXI) and netapp snapshots made every 4 hours. Lately all my snaps are as big as about 90GB which is crazy !

How can I figure out which one of the VMs is making so many changes ? Any tool is welcome.

 

Thanks in advance,

you can lock direct on vmware under performance tab on esxi host, and view under advanced show the write rate or write requests as stacked graph per VM.
