To analyze the Statistics by users for transactions and programs use transaction STAT

STAT looks at the STAT file created by each SAP Instance.

It is by default 100 MB.  Every hour there is a COLLECTOR_FOR_PERFORMANCE job RSCOLL00 aggregating this data into MONI table.  It will truncate STAT file once the specified  limit is reached.

So, you can see details for however many days in this 100 MB using STAT, or ST03 to see the MONI aggregated data.

To change the 100 MB limit, ST03 -> Goto -> Parameters -> Performance Database.

If you wish to extract the Statistics by ABAP program, you can refer to this program :-
