Using the Expert Mode

The System Log utility has two modes: normal and expert. The expert mode is intended primarily for use by SAP should it become necessary to analyze a problem in your system. To enter expert mode, choose Edit ® Expert mode.

In expert mode, you have a number of additional selection options you can use. You can also exclude or include specific system log messages.

Setting Expert Selection Options

Choose the Attributes button to display the following fields:

Attribute	Description
Program	Restricts the display to messages from one program.
Problem classes	Limits the report to a specific message type. You can enter one or more of the following message classes: K system kernel messages from the Basis system S status messages T transaction messages W warning messages X other types of messages
From file/position To file/position	Defines the segments of the log file that are read. If you have already read the system log once, you can determine the file and position of a particular entry by double-clicking on the entry. An entry’s detail page contains the entry's file and position in the Technical Details section.
Message format (Type)	Selects messages by system component format. To do this, enter the code letter for a component’s SysLog type. To list component formats, use the Possible Entries button.
Terminal	Selects messages from single-place computers, such as PCs, enter the network hostname of the PC. See the F1 help for additional formats for search specifications.
Development class	Restricts the display to messages issued from modules in a development class. The TDEVC table lists the available development classes.
With internal SysLog entries	Displays messages from the system log's send and collection processes. With these entries, you can check that the send processes in application servers are successfully communicating with the central collection process. See Understanding Central Logging Concepts for more information on the send and collection processes.

You can use the Message IDs function to exclude specific message types from a report or include only specific message types in a report.

Displaying a Log Report

To display system logs, choose Tools ® Administration from the R/3 initial screen. The system displays the System Administration initial screen. Choose Monitor ® System log. The System Log initial screen appears.

The System log entries imported field shows how many log entries the system has read from the log file. When you first enter the System Log initial screen, this field is set to 0. Choose Reread system log to read the log The system then reads in entries from the log file so that you can display them. By default, the system reads the log for the last one to two hours.

If you have read a log, the toolbar contains Redisplay only and Read in Syslog buttons along with the Refresh Syslog :

Choose Redisplay only to view the last system log you displayed. If you like, you can use the Selection options along with this button to refine the old system log data without re-reading the log.

If you want to retain the data from this last read, but want to reread the system log with different selection criteria, use the Read in SysLog option. This option lets you mix the information from an original log access with a second log access into one list.

Setting Selection Criteria

You can tailor the information you want to pull from the log using the selection criteria.

Reading Logs on Remote Systems

If you like, you can read the system logs on other application servers in your R/3 system. Choose System log ® Choose to select a log. You can display the following logs

Log	Displays
Local system log	Messages issued by the application server you are currently logged onto. This is the default.
Remote system log	The system log from an application server other than the one you are logged onto. To display a particular remote system, use the Instance name option.
All remote system logs	The logs from the system you are logged onto as well as from all the other application servers that make up that R/3 System.
Central system log	The central log. To use this option, you must have previously configured each application server to forward the messages from its local log to the central log. The information in the central system log may differ from the data in the individual system logs. See Concepts of System Logging for information about the log file accuracy.

Environment Utilities

The Environment menu provides the following functions:

Display SAPPARAM	Displays the settings of system log parameters in the system profile.
Show authorizations	Shows the authorizations required for the system log.
Clocks	Displays the system clocks that were used for message time stamps. Checking system clocks is useful if you need to clarify time discrepancies between messages from different application servers. The display shows whether the system clocks of your R/3 systems are set to the same time.
Process status	Displays the current state of the system log's send processes.

Setting the Log Entry Presentation

Use the selection screen to determine what information is displayed for the individual log entries. To do this, choose Goto ® Layout. In the Expert Mode , you can also display the Development class and the Date.
