How to get IoT Edge Custom modules using Kusto query

Question

Hi All

I have an IoT Edge Device which contains multiple modules including custom module. I have to get the running status of all such modules but not able to get such information. Using below query, I got only IoT Edge system modules but not custom modules. Also not having such information of running status in the output of below query.

Is it possible to get all these information using Kusto query? Or do we have any other alternative way to information about IoT Edge Custom modules?

Thank you in advance!

Hello @Khandu Shinde ,

welcome to this moderated Azure community forum.

I'm not sure if the diagnostics of the IoT Hub expose this information.

But there is a more obvious way.

If you build a serious IoT solution, you probably start collecting IoT hub system events for audit or historical purposes.

Check out the events. This blog post explains what is shared regarding iot edge module-related messages.

Notice this relies on event application settings, those are not imported into Azure Data Explorer without moving them into the message body. In more detail, the data connection mapping does not support those properties.
