IoT Core CloudWatch rule

Hello

Yes you can create log stream per IOT thing. I posted a few articles that details how to do so below. You can also set logging per device even if devices are not registered as an IOT Thing. This is described in this post.

In AWS IoT, you can configure resource-specific logging using the CLI to set logging levels for individual thing groups (as detailed here). Thing groups can be nested, allowing logging settings to apply hierarchically, with child groups able to override parent configurations. A thing inherits settings, policies, and logging levels from the groups it belongs to, provided the client ID matches the thing name (or via exclusive thing attachment otherwise). Beyond thing groups, logging can also target resources such as client IDs, source IPs, and principal IDs.

When your client ID matches the thing name, AWS IoT Core will automatically associate the client session with the corresponding thing resource. This allows the client session to inherit the configurations and settings applied to the thing groups to which the thing belongs, **including the logging levels. **

Hope this helps,
