Sorry, you have lost me a little bit. When you say dynamically turn on/off loggers I am assuming you really mean enable/disable filtering on those Loggers?
Are you thinking that the rules can be added or removed dynamically? Or just the parameters to the rules? I ask because you can’t really add a Supplier dynamically if it is part of the configuration. Log4j will process the configuration only when it is changed. However, the data they rely on can come from anywhere - more or less how we use Lookups to evaluate conditions on every log event.
