> Use the function of the ${} placeholder in <KeyValuePair> value to output the relevant value when there is a value defined by ${} in the context. If not, it will be output as it is. In <PatternLayout> pattern, you can use %X{} to exist. If the output related value does not exist, it is an empty string. There is no such function in KeyValuePair.
