Aerospike has cmd like redis's MONITOR?

Aerospike has cmd like redis’s MONITOR? To debugging command that streams back every command processed by the Aerospike server.

Kind of. You can tell aerospike to report data operations against a namespace, which will log the srcip/user/namespace/set/key but its not dynamic and doesn’t show much details for batch/scan/query volume. Unfortunately it isn’t a dynamic setting, and you might have to have security enabled.
