> # Add a new metric of the number of times the 
> DatanodeManager#slowPeerCollectorDaemon thread collects SlowNodes, and 
> display it in a map structure.
>  # The same SlowNode may always appear in the prod env, so when 
> slowPeerCollectorDaemon is turned on, record the number of times it has been 
> collected by the slowPeerCollectorDaemon thread. If the collection frequency 
> is too high, SRE or DEV need to repair the machine.
