I was thinking of selecting a table, and then seeing the graphs for
that table.  Not seeing all of the graphs for all of the tables at

I am just interested in seeing this data, but I am not sure wha the
best way to forward is.  I am not familiar with OpenTSDB,  I also have
questions. How difficult is OpenTSDB to setup?  What capabilities will
offer us?  I.e. does it make it easier to slice and dice the temporal
data and plot it in different ways?  Doing this per table view in the
monitor page would be a custom transformation of the data. If OpenTSDB
could allow us to view this data w/o writing something custom that
does sound appealing.  Could we possibly offer an OpenTSDB view out of
the box w/ Accumulo?  The monitor is custom, but its very nice having
it out of the box.
