A) A functionality can be added to Master Component so that active/standby status of route can be known.

Consumer consumer = route.getConsumer();
if (consumer instanceof MasterConsumer) {
        MasterConsumer master = (MasterConsumer)consumer;
        if (master.isMaster()) {
              // do stuff
        }
}

MasterComponent might needs this method for that within MasterConsumer class :

public boolean isMaster() {
   return singleton.isMaster();
}

B) Master component state should also be shown in hawtio. Within Camel Tab where it display route-list, there we can display a flag/icon/value to specify that if route is Master or standby. This would help user to easily identify route status.
