It's true that events don't correlate directly to commands, but they do correlate to the state of the system and that is affected by commands.

events are time stamped. In non-human mode, I think command responses should be time stamped too so that a management tool knows when the event was generated and can correlate the system state to the particular event.

Timestamping doesn't help since the command could have been delayed in the monitor socket.

Further, we're now so deep down the complexity spiral that it has now become the most complicated piece of code in the entire system.

You certainly cannot believe that, can you?

Surely the best way to synchronize events is to keep them on one timeline?

Can you show exactly how you would expect things to work in the monitor output? I'm having a hard time understanding what you're suggesting.
