Features

List Format

This is a standard human readable format that can be parsed and is used by the Log Viewer and AS Java. List formatted logs are written to a file whose values are separated by a hash (#).

For more information, see List Log Format 2.0

There is a specific list formatted log file called Change Log. It gives information about all configuration changes made on the AS Java. It also shows the ID of the user who has made the change. The log file path is: <SAP_install_dir>/<system_name>/<instance_number>/j2ee/cluster/changelog.

For example:

Syntax Syntax

###C0000A37462200010000000301BE2893###configtool########Thread[Thread-5,5,main]#Plain##

End of the code.
Text Format

This format is relevant for text log files and has random structure. For example:

Syntax Syntax

  1. <!--LOGHEADER[START]/-->
<!--HELP[Manual modification of the header may cause parsing problem!]/-->
<!--LOGGINGVERSION[1.5.7.1006]/-->
<!--NAME[D:\usr\sap\LKG\J00\work\deploy.trc]/-->
<!--PATTERN[deploy.trc]/-->
<!--FORMATTER[com.sap.tc.logging.TraceFormatter(%25d[%s] %m)]/-->
<!--ENCODING[UTF8]/-->
... 
<!--LOGHEADER[END]/-->

...  
  Additional information:  
  ] [ASJ.dpl_dc.001048]
...
End of the code.
Trace Format

This format is the same as text format. However, it has a particular structure. For example:

Syntax Syntax

  1. %24d %-40l [%t] %s: %m
End of the code.

where,

  • %d is a timestamp in a readable format.

  • %l is the location on behalf of which the message has been created.

  • %t is the thread that has emitted the message.

  • %s is the severity of the message.

  • %m is the message text.

The numbers in the pattern denote the number of characters for an item. The corresponding output is the following:

Syntax Syntax

  1. Dec 01, 2007 10:10:00 PM com.sap.FooClass.fooMethod [main]
Fatal: A sample fatal message
End of the code.
