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.

I'm trying to pull the most recent configuration backup from my clustered netapp. 7mode allows you to do a simple 'config dump' but looks like its a bit trickier to get for CDOT. Does anyone have experience/knowledge on pulling CDOT config backup files via the API ? Thank you.

I am having an issue in many production scripts that are taking advantage of the 'Connect-NcController -Transient:$true' functionality to not set the global variable when connecting to a controller, and instead assign that connection to my own custom variable. It all works fine, except the first time I try to do ANYTHING with that connection it will fail with a generic error coming from the module commandlets. The same action will work fine the second and every other time after that first failure. Get-NcAggr : Object reference not set to an instance of an object.
