ONTAP SVM dashboard - Qos sequential reads and writes - high value #2947

Problem

As soon you upgrade to ONTAP 9.13.1P8 the values of the "Qos Sequential Reads and Writes (%)" are higher then 100% because the unit is percent (0.0 - 1.0). When changing the unit to "percent (0 - 100) it matches again. Probably that is because REST gives different return values

@BrendonA667 I have checked the qos_sequential_reads and qos_sequential_writes metrics in both REST and ZAPI, and the data is consistent across both collectors.

Regarding the SVM dashboard panel for QoS Sequential Reads and Writes (%), the value of this metric at the workload level can reach up to 100%. Therefore, summing these values is not appropriate as it will still exceed 100%. Adjusting the unit from 0-1 percent to 0-100 percent will not resolve this issue. The proposal is to remove these panels from the SVM dashboard and add them to the workload dashboard instead, where we will display the top QoS sequential read and write metrics at the workload level. Does that sound good?

@BrendonA667 Does above solution work for you?
