    @r7raul1984 how do you think expose `CountMetricFilter`  as a parameter to choose which
metric to convert as `count`, and the current hard-code behavior should only be some kind
of default implementation?
    
        @FunctionInterface
        interface  CountMetricFilter extends Function<Map, Boolean>
       
        DefaultCountMetricFilter = (metric) -> metric["metric"].endsWith("*.count")

> Some metric like hbase hadoop.hbase.regionserver.server.totalrequestcount is counter
type(the value is always increasing).We will save the rate of change of the value over a step
period.
