SAP’s EarlyWatch™ online diagnosis and analysis service provides a performance report
based on over 100 screens available from SAPGUI and other utilities
(SAPDBA utility no longer available on SAP 6.40).

Its Tune Summary reports load on R/3 buffers and other memory areas.
Buffer hit ratio = Buffer object reads / logical requests.

| ST03 | Workload distribution Monitor
| A technical analysis uses this monitor to identify and analyze problems in the database, R/3 memory management, or R/3 buffers.
An application analysis uses this monitor to identify and analyze transactions, programs, and users that place a heavy load on the system.

load on the database buffers, database locks, wait situations, read and write access to hard disks, and SQL statements.

| DB02
| CCMS > Control/Monitoring > Performance Menu > Database > Tables/Indexes > Database Allocation > Detail Analysis (consistency check)
| Analyze tables and indexes (missing database objects and space requirements).
Database Performance:Database Allocation monitor, Check Table Within SQL Server,
the DBCC CHECKDB command locks user tables, indexes and system tables when running.
It is very I/O intensive and should therefore not be run during normal operation, but at times when the system load is low. For more information, see SAP Note 142731 DBCC Checks of SQL Server.

| DB12
| CCMS > DB Administration > Backup logs > CCMS Monitoring Tool > Backup history > Logs Backup.
| Overview of backup logs (DBA protocols).
In Backup Restore Information list, find the largest transaction log backup.
Select a row and then History info to find the number of pages backed-up.
Calculate how much free space is left on the transaction log disk by subtracting the
amount of space used in the transaction log is the number of dumped pages, multiplied by 8 KB.
The SAP log file is initially created with a default size of 1 GB, with
the smallest disk normally 9 GB.

valid:
To list users last login, invoke report RSUSR006.
The preferred method of navigation for the experienced SAPGUI user is to retrieve screens by
name (TSTC code) rather than through the series of pull-down windows
because the screen names do not change between releases of SAP,
but the structure of the pull-down menu path changes frequently as SAP is upgraded.
