There is no out-of-the-box support for level-specific patterns in 
logback at this time.

You could of course write your own layout which does what you describe.
See http://logback.qos.ch/manual/layouts.html#writingYourOwnLayout
for documentation on this topic.

Alternatively, you could write a custom conversion specifier. If you had 
a specifier called %debug which output contents only for level DEBUG, 
and a %warn specifier which output contents only for level WARN and 
another specifier %ERROR which output contents for ERROR, your pattern 
could be written as

%debug(%level %d %t) %error(%level) %info(%level) %m%n

See http://logback.qos.ch/manual/layouts.html#customConversionSpecifier
for documentation on this topic.
