Monitor tblspaces and extents

Monitor tblspaces and extents to determine disk usage by database, table, or table fragment. Monitoring disk usage by table is particularly important when you are using table fragmentation, and you want to ensure that table data and table index data are distributed appropriately over the fragments.

Run oncheck -pt to obtain extent information. The oncheck -pT option returns all the information from the oncheck -pt option and the additional information about page and index usage.
