Zhuoyue Huang commented on HBASE-25914:
---------------------------------------

[~stack]  [~vjasani]  Thanks for the comments. If there aren't any new suggestion, I will push a new commit following the modification below
h1. Rename text
 # Tab 'Named Queue Logs' rename to 'Operation Details'(Every record saved in named queue framework ring buffers are about 'opeartion' information)
 # sub-tab 'Slow Logs' rename to 'Slow RPCs '
 # sub-tab 'Large Logs' rename to 'Large Response RPCs'

h1. Explanation
 # Explanation of the main tab 'Operation Details'

 
{code:java}
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
{code}
        2.  Explanation of sub-tab 'Slow RPCs'

 

 
{code:java}
Slow RPCs record those RPCs whose processing time is greater than the threshold (see the setting 'hbase.ipc.warn.response.time' for details)
{code}
        3.  Explanation of sub-tab 'Large Response RPCs'

 

 
{code:java}
Large response RPCs record those RPCs whose returned data size is greater than the threshold (see the setting'hbase.ipc.warn.response.size' for details)
{code}
 
h1. RPC full display opt-in switch

The setting 'hbase.regionserver.slowlog.buffer.enabled' has determined whether to record slow/large log on RegionServer, and this setting also determines whether the UI is displayed. If set 'hbase.regionserver.slowlog.buffer.enabled' as false. the slow log UI on RegionServer does not show up
