Hi Gergely, This short version of my question: Can I set the Run Schedule value dynamically? I have an array of different sensors that need to be polled and have value saved/reported. This would be a sample flow: I need to be able to change the interval of each sensor pulling. I'm thinking the Monitor Controller being able to receive a json message such as: { "Sensor1": 60, "Sensor2": 600, "Sensor3": 600, } To set Sensor1 to 60s interval, Sensor 2 and 3 to 10 minutes. Then send in: { "Sensor1": 600, "Sensor2": 60, "Sensor3": 60, } To change Sensor 2 and 3 to 60s and Sensor 1 to 10 minutes when needed. I need the flow to be autonomous beyond the control messages. I can't have an external event "poke" the pollers constantly. Don't know if there is a way to do this in NiFi or if I have to implement my own bookkeeping in a custom processor. Thanks. ... View more
