As seen in MB-56483 ns_server computes "rate" stats using information from sigar as well as elapsed times in ns_server. Because of this the rates may end up "fuzzy" (> 100%).

|The Cluster Manager’s computed utilization stats were inaccurate due to time interval discrepancies in components where data was collected.
|The Cluster Manager now reports raw stats as Prometheus counters.
