Issue

The resource headroom statistics which includes the utilization, operations and latency values provides headroom guidance on a per resource basis. 

Workload statistics provide details of how much of a given resource certain workloads are consuming. 

  • Selecting the best resources (node/aggregate) for a new workload
  • Selecting the best destination resources for moving an existing workload
  • Helps to determine when a resource has reached capacity, or is overloaded
  • When selecting the most appropriate destination resources, the confidence factor provides guidance on the accuracy of the current headroom values
  • Help identify workloads which are too high for a given node.
