An approach, executed by a computer, for adjusting polling parameters. The approach includes one or more processors polling an endpoint application using an initial polling quantity and an initial polling frequency. The approach includes determining a first number of events not consumed in a queue of a listening application and a second number of events in a queue at the endpoint application at an end of a polling cycle. Furthermore, the approach includes adjusting at least one of the initial polling quantity and the initial polling frequency based, at least in part, on a comparison of the first number of events not consumed in the queue of the listening application and the second number of events in the queue at the endpoint application at the end of the polling cycle.
