> ```Partitioner``` enable us to dispatch the data to the specify partition as 
> we wish. However, we can't observe the partition metrics if they are on the 
> same broker. The root cause is that the key of topic metrics doesn't contain 
> "partition" so all partitions on the same broker are merged into single 
> metrics (see attachment).
