The history collection database.
The history table contains a point by point rolling
history of the most recent RTT operations for each
conceptual RTT control row. The rolling history of this
information is maintained in a series of 'live(s)', each
containing a series of 'bucket(s)', each 'bucket'
contains a series of 'sample(s)'.
Each conceptual history row can have lives. A life is
defined by the rttMonCtrlOperRttLife object. A new life
will be created when rttMonCtrlOperState transitions
'active'. When the number of lives become greater
than rttMonHistoryAdminNumLives the oldest life will be
discarded and a new life will be created by incrementing
the index.
The path exploration RTT operation will be kept as an
entry in this table.
