What's wrong with good ol' OEM's Capacity Planner? I found it works great for tracking I/O, CPU, storage (at any level), and memory usage for any system. You can even create your own queries in case you want info broken up in a different way, such as storage being allocated into logical areas. CP roles up the information by hour, day, week, month, and year, easily lets you graph data you have (and change criteria and regraph quickly), plus estimate for x amount of time in the future based on current trends.  

This does nothing for a system yet to be developed, but sure is helpful for an existing system, especially since the graphs are the eye candy that management responds to, when requesting more hardware.

Thatīs right, it is a Crystall Ball! That is probably why many Capacity Plans fails! I guess there is no scientific way to perform capacity plannnings, at least not for new applications and without some metrics.

Thanks

LiShan, capacity plan is a crystal ball usually required by damagement. If it is pretty enough and is web based, it doesn't necessarily have to have anything in common with reality and accuracy. Capacity plan is like light saber model: your can be prettier then mine, but neither will work. The answer to the question "how much disk will we be using in 6 months" is still: "I have no clue", especially if the application is new to your system. Fortunately, there is a great tool called "Oracle Application Express" which, in combination with good, old DBMS_JOB can do the trick. You can schedule monthly space allocation collection and then present a bar graph on the intranet. You can even allow the damagement to select a month in the future for which it wants to see allocation. It's called "Futurama". May the farce be with you.
