My point is on Feb 7th (second pic), packets are delayed upto 4 minutes, on Feb 8th packet delay is only in milliseconds which is normal.

We have some "Connection reset by peer" errors from HDFS, so I am correlating this metric with the errors.

“Send Data Packet Blocked...” is this metric related to network packet delay?
