Report raw stats instead of computed stats

    Description

      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%). As prometheus provides a rich set of formulas the stats should be reported to prometheus as raw stats instead of computed stats.

       

       

      Issue Resolution
      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.
