> For many existing metrics frameworks, they focus on maintaining metrics in 
> memory independently for each instance. However, kylin server may consist of 
> multiple instances. Thus we extend existing metrics framework by introducing 
> *active reservoir* to actively push metrics to reporters which will report 
> metrics of its instance to a unified storage. 
> Here we introduced two *active reservoirs*. One is called 
> {{BlockingReservoir}}, which will buffer the metrics. The other is called 
> {{InstantReservoir}}, which owns no buffer and will directly push metrics to 
> reporters.
> Generally, one *active reservoir* can push its metrics to multiple reporters 
> and one reporter can only listen on one *active reservoir*.
