>
> Key: HDFS-16917
> URL: https://issues.apache.org/jira/browse/HDFS-16917
> Project: Hadoop HDFS
> Issue Type: Task
> Components: datanode
> Reporter: Ravindra Dingankar
> Priority: Minor
> Labels: pull-request-available
> Fix For: 3.4.0
>
>
> Currently we have the following metrics for datanode reads.
> |BytesRead
> BlocksRead
> TotalReadTime|Total number of bytes read from DataNode
> Total number of blocks read from DataNode
> Total number of milliseconds spent on read operation|
> We would like to add a new quantile metric calculating the transfer rate for datanode reads.
> This will give us a distribution across a window of the read transfer rate for each datanode.
> Quantiles for transfer rate per host will help in identifying issues like hotspotting of datasets as well as finding repetitive slow datanodes.
