Good logs do

For some definition of "where" :-)

it's my experience that a full stacktrace is needed (or at least super-helpful) when debugging, since the innermost (triggering) level is not always the level where the problem was introduced. Getting full context (including the values of local variables) all the way up the stack makes that puzzle a whole lot easier.
