Get Online/Offline status for iot thing using iot device client sdk

Question

Hello, I was wondering if there's any easy and fast implantation way to get online/offline status in the console as soon as a iot thing comes online or goes offline. Any help is appreciated.

Accepted Answer

Hi Subham. You may be interested to enable fleet indexing, particularly thing indexing and thing connectivity: https://docs.aws.amazon.com/iot/latest/developerguide/managing-index.html

With that enabled, you can then do searches within the console (Manage->Things->Fleet Indexing->Search). Example queries: https://docs.aws.amazon.com/iot/latest/developerguide/example-queries.html

You can use FleetHub so you have a GUI reporting connection status and last disconnection reason:

https://docs.aws.amazon.com/iot/latest/fleethubuserguide/aws-iot-monitor-user-queries-dashboard.html

Fleet Hub works on top of fleet indexing, so fleet indexing needs to be enabled.

Please also be aware of Lifecycle Events; you can enable these and have AWS IoT Rules that action 
these events: https://docs.aws.amazon.com/iot/latest/developerguide/life-cycle-events.html

Answer

Another option is to use [lifecycle events](https://docs.aws.amazon.com/iot/latest/developerguide/life-cycle-events.html) and subscribe with the MQTT test client in the AWS IoT console (or any other MQTT client)  to `$aws/events/presence/connected/#` and `$aws/events/presence/disconnected/#`. If you want to get messages for a certain client only replace `#` with the `clientId`.

Answer

Hey Greg and Phillip, thank you so much for the answer, it helped a lot. However when i used lifecycle event of connected or disconnected i found that only when the rpi is shutting down i am getting the mqtt message but when the `device loses the connectivity ` i am not. Can you tell me if there's a way to implement this?

Answer

Thanks all for the inputs, the `keep_alive_secs` works when the device client is being run via a service. Couple more doubts
1. I want to use lifecycle events to notify me via SNS which isn't working it keeps saying invalid sql statement when i did `SELECT * from '$aws/events/presence/connected/+'. 
2. The whole implementation seems very very tedious and it would be great to have tutorials for things like this.
