----------------------------------------------------------------
[~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 any rpc records
