Expected/desired behavior

It seems that currently version of ELMS only supports retrieving logs from top-layer edge devices. InvokeUploadModuleLogs function invokes UploadModuleLogs with SasUrl of azure blob storage's public endpoint. According to this link to retrieve logs from devices behind gateway it should use something like "https://$upstream:8000/myBlobStorageName/myContainerName?SAS_key" instead.

It would be great if InvokeUploadModuleLogs could identify edge devices behind gateway (e.g., having a parent device) and generates appropriate sasUrl for them.

OS and Version?

Windows 7, 8 or 10. Linux (which distribution). macOS (Yosemite? El Capitan? Sierra?)

Versions

Thanks! We'll be in touch soon.

This is fixed.. the last PR that was merged(fixing the event hub api version) did it I guess. I had applied the change in my local branch, but I guess it wasn't working because the deployment template was referring to the template in this repository... Thank you so much!
