ST06 TAMP > Operating System > Local Operating System Monitor reports load on the CPU and the physical main memory. (such as what is reported by Unix command lsattr -E1 sys0).
ST07 TAMP > Operating System > Remote Application Monitor reports load on the CPU and the physical main memory by application.
App Server ST02 TAMP > Setups/Buffers R/3 Memory Configuration Monitor (also known as the function Setups & Tune Buffers). Its Tune Summary reports load on R/3 buffers and other memory areas. Buffer hit ratio = Buffer object reads / logical requests. poor Buffer Quality = saved database calls / (database calls + saved database calls)
STAT - Single statistics records on the application server.
Work Processes SM66 CCMS > Control/monitoring > Work process overview or
TAMP > Exceptions/Users > Active users > All processes.
Systemwide Work Process Overview
SM50 TAMP > System monitoring > Services > Process Overview Local work process load (CPU utilization).
Shows the currently executing WPs on a dialog instance.
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.
DB AL02 - Oracle Database Monitor
ST04 CCMS screen that displays Oracle database activity.   Database Performance Monitor displays 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.

R/3 Tablespaces

Type Tablespace Contains Tables Size Activity
Transaction Tablespaces PSAPBTABD Holds SAP Transaction tables holding order headers, line items, purchase orders, etc. Large Highest
PSAPSTABD Master data and transparent tables with high write activity such as item master, customer data, pricing, etc. Largest Highest
PSAPUSER1D Defined to hold user customization (customer tables) not defined with the SAP software. Depends Depends
PSAPVB0101D & PSAPVB0102D - Large Very high
BASIS Tablespaces PSAPDICTD ABAP data dictionary (usually cached in memory due to frequent reference). Small Low
PSAPLOADD ABAP report loads and screens. - High
PSAPSOURCEID ABAP report source code and screens. - Medium
PSAPPROTD A heavy-use tablespace. Spool, customer, log files, reports and printouts generated by any SAP process. - Highest
System Tablespaces PSAPPOOLD System pool tables that SAP considers too small to be in their own tables. These are generally buffered in memory, so they're accessed at SAP startup time but not heavily after that. Small Low
PSAPCLUD Cluster tables used by SAP as subtables containing LONG RAW datatypes, which must be reorganized using Oracle's slower Export/Import utilities instead of Oracle's faster CREATE TABLE AS SELECT command. Large Medium
PSAPDOCUD Contains codument tables, including SAPscript and SAPfind tables. Small Low
PSAPVB0201D & PSAPVB0202D - - -
