Hi guys, short question what is the difference of the metric node_volume_total_data vs. node_total_data? When I compare them they look almost the same

The node_total_data metric is collected directly from ONTAP. node_volume_total_data is an aggregated metric calculated by Harvest which is the sum of total data across all volumes on a node.

Thank @jolly kindle for the explanation. So that means node_total_data would be better for a clear picture how the node is utilized?

Yes, I think node_total_data is better since it is coming from ONTAP directly.

thank you for clarification. Would it be possible to describe the difference on the ontap-metrics documentation a bit deeper?
