Adding, Editing and Removing Log Formatters 
Each log destination type can print messages in different formats: TraceFormatter, XMLFormatter, and ListFormatter. This procedure describes how you manage log formatters using the Config Tool.
More information: Formatter.
Note
You can configure and manage formatters for existing destinations only.
Start the Config Tool by double-clicking the configtool script file in <SAP_install_dir>/<system_name>/<instance_name>/j2ee/configtool directory.
Choose .
Select any formatter from the tree and then choose New.
A dialog box appears.
Specify the name of the new formatter.
Choose OK.
The new formatter appears in the Formatters tree.
From the Formatters tree, select the formatter you want to edit.
From the Type dropdown box, specify the formatter type.
You can choose from the default ones:
ListFormatter – formats a log record that can be transferred to and processed further by another application (for example, by Log Viewer).
TraceFormatter – a human readable format. You can specify a pattern to this format. If you do not specify such, a default one is created.
XMLFormatter – formats log records as XML elements.
Choose the Pattern field to configure the formatter.
Note
For the TraceFormatter you can make configuration, using a custom formatting pattern. The pattern enables you to specify the message data fields, with placeholders of the form %[[-]<width>[-]]<type>.
Choose

From the Formatters tree, select the formatter you want to remove.
