zhuhaifeng updated FLINK-4840:
------------------------------
Description:
There will introduces the OperatorSystemMetricGroup, which encapsulates the
insantiation of TPS meter, lantency/proc_time_cost histograms.
Operator related System metrics are not instantiated directly by the specific
Operator, but instead within the OperatorSystemMetricGroup contained in the
respective OperatorMetricGroup. They are then later accessed by relevant
components(maybe different places), instead of instantiated them identically
with static name constants. Other system scope metrics (maybe
delay/queue_in/queue_out) can add into the OperatorSystemMetricGroup some later.
TPS: collect records per second(StreamSource), processed elements per
second(other operator)
lantency/proc_time_cost : collect an record time cost(StreamSource), processed
an element time cost (other operator)
