Wow, that's a nice feature. Any idea what the overhead is for this (not
that we'll be moving to 9i for at least a year)?

MONITORING USAGE | NOMONITORING USAGE
Not much at all, you can use monitoring in Oracle 8i.
Since it only writes the changes every few hours, it has very monitor
impact.
Do not criticize someone until you walked a mile in their shoes, that way
when you criticize them, you are a mile a way and have their shoes.

Mpnitoring has to do with tables not indexes. There is no alter index index_name
monitoring statement in 8i. I don't know about 9i as I haven't looked at it yet.

Not really - but you could move it into its own
tablespace and then monitor reads/write on this tspace
using v$filestat.

You mean the last time the index was accessed by a query or the last time
the index was modified?
You probably mean the first one, but just in case you mean the second one
here's a query I use for tables. It can be modified for indexes by changing
type# to 1, I believe.
