Jagadesh Kiran N commented on HDFS-9509:
----------------------------------------

[~szetszwo] ,Currently along with 
{code} sendDataPacketBlockedOnNetworkNanosQuantiles {code}& {code}sendDataPacketTransferNanosQuantiles
{code},
already some more metrics are there in trunk for example
{code} 
 ramDiskBlocksEvictionWindowMsQuantiles 
ramDiskBlocksLazyPersistWindowMsQuantiles,
packetAckRoundTripTimeNanosQuantiles,
flushNanosQuantiles,
fsyncNanosQuantiles 
{code}
 are there, Can you please suggest if any other metrics is required ?

> We already have sendDataPacketBlockedOnNetworkNanos and sendDataPacketTransferNanos for
the transferTo case.  We should add more metrics for the other cases.
