Description

The level in a pattern layout can be defined as:

%level{length=n}

For example:

%level{length=1}

Which will give you log level names:

• I for Info
• W for Warning
• D for Debug
• and so on.

If n is greater than a level name length, the length of the level name is used.

Note that the level name computation is done when the pattern is created, thus having no impact on logging performance.
