@Andrej Treciak You can use Azure Monitor : https://learn.microsoft.com/en-us/azure/azure-monitor/platform/alerts-metric
Create an Alert in Blob storage, and keep the usage metric as the trigger with a threshold file size
Additional information:
- You may also refer to the suggestion mentioned "Getting blob count in an Azure Storage container"
- Also you can use Azure Function: In that function you will list the blobs in the blob container which needs to be monitored. Based on the count of the blobs returned, you could send an email from that function itself. More information about timer trigger for Azure Functions can be found here: https://learn.microsoft.com/en-us/azure/azure-functions/functions-bindings-timer.
Hope this helps! Kindly let us know if the above helps or you need further assistance on this issue.
