Operations Details
HBase uses some fixed-size ring buffers to maintain rolling window history of specific server-side operation details.
This page list all operation details retrieve from these ring buffers
Slow RPCs record those RPCs whose processing time is greater than the threshold (see the setting 'hbase.ipc.warn.response.time' for details)
