Samir Ahmic updated HBASE-15144:
--------------------------------
Attachment: HBASE-15144_v3.patch
Here is new patch with sync stats stored in circular buffer with size 10.
Regarding WAL roll time i think is self explanatory we are displaying time when
last roll time was happened and when next one will occur. Only alternative that
i can think of is to show list of times when roll happened. Also we can add
paragraph under "Procedure WAL State" table explaining in more details how
procedure Store works and what some of parameters mean like we do for regions
in "Regions" table.
> Procedure v2 - Web UI displaying Store state
