Goal

You want to know when an index is used.
When enabling index monitoring, it updates the V$OBJECT_USAGE.USED column value to "YES" when the index is (first) used.
However, enabling monitoring does not record any date information which states when the index is actually used.
Is it possible to track indexes that are not used for some period of time to possibly remove them.
