tracing events in event driven architecture

We are thinking of designing commands and events based architecture for our feature. One problem we observe here is that how do we debug or trace "what happen to these commands and events ?"

For example if i send "createUser" command and when the user is created, we will emit "userCreatedEvent". Are there any way to correlate these command and events ?

We want to track all the sequence of events completed or not. It will help us in debugging and identity what successfully executed and what events are not successfully executed.
