Data store utilization increase

Hi All,

Recently there was an increase in data store free space 52% reduced to free space 22 %. Free space has recently come down and wanted to find out what had made the data store utilization went high.

There are multiple VM's in a data store, hence it's not possible to compare each VM's.

Can we find out from script which VM recently migrated to data store/VM disk expended or grown/ backup snapshot had caused the data store utilization high ?

Thanks
