Embodiments of the present disclosure include a method, a system, and a computer program product for determining wait times of tuples within a streaming environment. The method includes monitoring one or more tuples being processed within an operator graph where the operator graph includes a first processing element and a queue of the first processing element. The method includes recording a wait time of the one or more tuples within the queue of the first processing element. The method includes recording a processing time time of the one or more tuples within the first processing element. The method includes displaying the wait time and the processing time of the one or more tuples. The method includes optimizing a configuration of the operator graph, in response to recording the processing time of the one or more tuples.
