The frequency of the file statistics collection can be controlled through ST03 -> Collector and Performance DB -> Performance Monitor Collector -> Execution Times. For the table history, you need to loook at the entry for report name RSDB_TDB (in older releases: RSORATDB). If the setting is correct, you should check the job logs of the job SAP_COLLECTOR_FOR_PERFMONITOR at the time when you were expecting the collection to run. You can also submit a manual collection through DB02 -> Refresh File Statistis (Background). This will submit a job RSDB4090, and if you don't get the history data as expected, you should check its job log for potential errors. If this doesn't solve your problem, you can open a customer message for SAP, so that the SAP support can look at your system.
