It gets data from Oracle ZFS via REST API.
Note that very old firmwares like 2013.06.05.3.0,1-1.14 are not supported.

Oracle ZFS Storage is collecting only a limited set of storage metrics by default.
XorMon needs to create additional datasets necessary to get more detailed performance data from the storage.
Datasets are grouped into several Worksheets named STOR2RRD_*, all are created automatically during the first run.
