IoT Platform imposes limits on the frequency of connection requests, the frequency of upstream and downstream communication, and the frequency of message forwarding. When the limits are reached, throttling is triggered, and this will have an adverse effect on the daily operation of your business. With the monitoring and alerting functions of CloudMonitor, you can receive alert notifications to perform corresponding business adjustments in a timely manner.
