Note
The Message field in Log Viewer has maximum size of 64 KB.
This is a standard human readable format that can be parsed and is used by the Log Viewer tool and AS Java. List formatted logs are written to a file and its values are separated by a hash (#). More information: List Log Format 2.0
There is a specific list formatted log file called Change Log. More information: Change Log
This format is relevant for text log files and has random structure.
Example
<!--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]/--> Feb 24, 2009 12:48:16 PM [Info] [Server 00 00_37057] (11354): Deployment status of [sap.com_ATSFormalTestApplication365900472] was changed from [Delivered] to [Success] [ASJ.dpl_dc.006301]... Additional information: [ASJ.dpl_dc.001048] ...
This format is the same as text format. However, it has a particular structure.
Example
%24d %-40l [%t] %s: %m
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:
