I am trying to use the new RoutingAppender of Log4j2 to route the different logs based on the MDC (ThreadContext in Log4j2). What I want to do is the following:
I want to achieve this using a wildcard pattern in the tag and then filter using the key parameter in the for contextId (${ctx:contextId}) and using the default (without key paramenter) for the main appender, however I don't know which value is that wildcard.
Any help is appreciated, maybe I am approaching this from the wrong path. I have been reading about Filters but don't seem to work as I want.
Thanks!

Filters allow Log Events to be evaluated to determine if or how they should be published. A Filter will be called on one of its filter methods and will return a Result, which is an Enum that has one of 3 values - ACCEPT, DENY or NEUTRAL.
Configuration: the root element of a log4j2 configuration file; the status attribute represents the level at which internal log4j events should be logged. Appenders: this element contains a list of appenders; in our example, an appender corresponding to the System console is defined.
This concept is known as Logger Hierarchy. Logger Hierarchy is made up of set of LoggerConfig objects with a parent-child relationship. The topmost element in every Logger Hierarchy is the Root Logger. If Log4j2 doesn't find the configuration file, only Root Logger will be used for logging with logging level as ERROR.
