The amount of I/O activity and the percentage change in that activity are represented visually, through the size and color of the cells, respectively. The cells that are larger in size indicate more I/O activity than the smaller cells. The largest cell would be that of the database that presents the greatest amount of I/O activity. The color of the cells is determined by the percentage change in the I/O resources used by the databases.

To analyze I/O activity across a subset of databases, use the Group menu to group databases according to Database Type. Click on a specific group to view the trend and forecast for memory utilization for all databases within the group.

The volume and percentage changes in the I/O activity are represented visually through the size and color of the cells, respectively. Cells that are larger have greater I/O activity than smaller cells. The largest cell would be that of the database with the highest I/O activity. The color of the cells is determined by the percentage change in the I/O activity during the specified time period.
