The support scheduler micro service provide an internal EdgeX “clock” that can kick off operations in any EdgeX service.
At a configuration specified time (called an interval), the service calls on any EdgeX service API URL via REST to trigger an operation (called an interval action).
For example, the scheduling service periodically calls on core data APIs to clean up old sensed events that have been successfully exported out of EdgeX.
Users also can call the API of command service to collect one device's data automatically.
