> > @huangzhaobo99 From my personal perspective, this pr is valuable.
However, I don't think it's a good idea to write this information into JMX
because JMX is meant for collecting statistical information. If we include
detailed information, it might cause some complications.

> @slfan1989 The idea mainly comes from the DatanodeNetworkCounts metric,
which is more complex and does not even perform cleaning operations on the key.

> ReadBlockIdCounts metric should not be a problem, and it also adds a
switch.
Hi @slfan1989, This metric should be okay, Could you please provide me with
a ticket for this? hoping to attract more people's attention, Perhaps there is
a better way.
