Hi Amila, It seems we cannot add hierarchical subscriptions for registry collections. I get the following exception from the event component. My topic is /registry/notifications/_system/config/repository/deployment/server/#. The '#' at the end was added because I need to receive events related to all child resources.
org.wso2.carbon.event.core.exception.EBRuntimeException: Topic name /registry/notifications/_system/config/repository/deployment/server/# is not a valid topic name.
