> @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.
It should not be a problem, and it also adds a switch.
