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. |
