+For example, when using <<value.scenarios.pub,pub scenario>> it's necessary to enable <<value.scenarios.pub._.metadata,metadata>> generation.

+WARNING: In order to measure latency accurately, the scenario should ensure that publishers reside on the same emqttb host with the subscribers.
+Otherwise clock skew between different load generator instances will introduce a systematic error.
