We are trying to fetch performance details in NetApp ONTAP, but we have noticed that we are unable to fetch 'read_data,' 'write_data,' 'read_block,' and 'write_block' metrics in volumes. Is there an API available that sends this data, or is there an alternative API to retrieve it?
Volume API: <host>/api/storage/volumes/
Similarly, we are using the same API for LUNs, disks, and various other storage devices.
