Trigger cloud function based on events in MQTT topics

In my application I want to get a notification whenever a device connects / disconnects from the IoT platform and take some action based on the event. As per link (  and link ( , the connectivity status (whether a device is connected / disconnected) will be published to the MQTT topic of iot-2/type/device_type/id/device_id/mon

One option is to have a service running 24x7 subscribed to this topic and take appropriate actions. Since in my use-case, number of such events is low, using a cloud function seems to be a cost effective approach. It would be good to have an option to set rules by which cloud function gets triggered based on events in any MQTT topic of IoT platform.

Alternate mechanism is: Similar to the way telemetry events can be routed to Message Hub, monitoring events could also be redirected to Message Hub. Cloud functions is already integrated with Message Hub, so this will complete the flow
