---------------------------------------
[~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
> Provide slow/large logs on RegionServer UI
