It's quite easy to display database data with WebChart utility. After loading the oramon performance data into database, I create a sample WebChart page to show the performance data, following is the CPU utilization chart.
We can display more data into one web page, such as different performance data of the database. We can create more pages from the demo page, such as display the CPU utilization of different database servers.
Then we can use HTML tree to build a nagivation page. Now we connect oramon and WebChart by scanomon utility to build a good Oracle performance monitor and analyze system. It's more flexable than most of the business solutions.
Some of my friends (DBAs or DBA supporters) are testing the oramon and WebChart performance solution.
