Oracle ZFS: Oracle-ZFS_Worksheets_and_datasets.htm
ZFS Storage is collecting just a limitted set of storage metrics by default.
STOR2RRD needs to create additional datasets necessary to provide more detailed performance overview.
Datasets will be groupped into several Worksheets on the storage named STOR2RRD_*
Please, do not delete these worksheets and datasets as they are necessary for STOR2RRD functionality.

NOTE:
Creating additional datasets will put a higer load on ZFS Storage CPUs.
Check your ZFS Storage CPU utilization before enabling the monitoring.
