@ayushtkn @Hexiaoqiao @tomscut Hi, sir. I think we should better push this
PR forward. Because it waste datanode's memory. As the below screeshot show ,
it has 27K networkError key values!!!

> In our prod environment, we try to collect datanode metrics every 15s through
> jmx_exporter. we found the datanodenetworkerror metric generates a lot.
> for example, if we have a cluster with 1000 datanodes, every datanode may
> generate 999 datanodenetworkerror metrics, and overall datanodes will
> generate 1000 multiple 999 = 999000 metrics. This is a very expensive
> operation. In most scenarios, we only need the topN of it.
