I have a network location where every hour a csv file gets dumped. I need to copy that file to an azure blob. How do I know that a file has been uploaded to that network drive. Is there something like a file watcher in azure which monitors this network location? Also, is it possible to copy a file from network location to an azure blob through code?
I'm using .net core APIs deployed to an Azure App Service.
Please suggest a possible solution.
You can use Azure Event Grid but as of today Event Grid does not support Azure File Share.
As your fileshare in on-prem the only way I see is that you can write a custom publisher which can run on-prem and uses Azure Event Grid to send the event to Azure Event Grid and a subscriber which can be Azure Function does the work you want it to do.

But it will only be an Event and not the file itself which has been added\changed and to do that you will have to then upload the file itself into Azure for processing as well. As the above way requires you to do two things I would recommend run a custom code on-prem which runs CRON job like and looks for the new or edited file and then uploads to Azure BLOB Storage and then execute Azure Function to do your processing task.
Since the files are on-prem you can use powershell to monitor a folder for new files. Then fire an event to upload the file to an Azure blob.
There is a video showing how to do this here: https://www.youtube.com/watch?v=Usih7UywZYA
The changes you need to make are:
