Check out the statspack viewer at

I played with it a little and it gives you graphs of the performance data gathered by statspack.

I plan to check it more thoroughly in the near future.

> hi, list friends:
> We know statspack can gather history data and let you compare statistics
from different time snapshot.But it is something difficult, for you must make multiple report and open them one by one and compare data between different reports.
> Now i want to gather some information about the system ,put them in log
file and draw pictures(using mrtg from log) about the statistics change,so that i can see which statistics is changing recent time and find problem before it became performance bottleneck or before it stuck the system.
> In fact, the most useful data i want to get is like the content in the
statspack, but i want to get them into one file from different time snapshot.The data i want to gather is like: wait event change trend,instance load profile change trend, the most cost sql change.Is it possible to get these data directly from some join of v$views? Or i can gather such valuable information from some v$view?
