"tablespace free space monitoring is done i think once every 15 minutes
only. It can be changed but that is the default. Unfortunately there is no
canned report for that but what i have done (when encountered such
requests), is to write sql and encapsulate that with some pre-set html and
use Google visualization. problem solved.

Google visualization has on advantage over Google charts, no data is sent to
servers but it is rendered in your browser only. For charts, their server
caches data for some time. For datafile monitoring, I am sure you can add
custom monitoring, it isn't very easy. But then again you have to ask
yourself, why do you need minute-by-minute monitoring?

BTW there was a bug in dba_free_space (which oem uses) in 10202/10203  and a
patch is available. Ensure it is applied so OEM can correctly identify free
space.
