How to tell spark plug have leaks

How to see if the spark plug have leak?
You can notice that the park plug have a color of a rust instead of white ashes, then the outer part of the spark plug have burn dirt, slightly black ... Well most spark plug must be change during tune up and after 6months to 1 yr of used also you can even feel the running performance of the engine if it okay or no good.
