I created a container in my storage account and uploaded a 10MB file (block blob) at Azure portal.
After about 3 hours, blob capacity at metric of the storage account increased about 10MB.
After that, I deleted the file and waited 12 hours and more, but blob capacity remained 10MB.
Need I wait more?

I want to monitor "blob capacity" using alert, so want to test it, but unable to decrease blob capacity.
If I can, I hope to increase/decrease blob capacity immediately to test it.

    Hello @roy

    Capacity metrics values are refreshed daily (up to 24 Hours). The time grain defines the time interval for which metrics values are presented. The supported time grain for all capacity metrics is one hour (PT1H).

    https://learn.microsoft.com/EN-us/azure/storage/blobs/monitor-blob-storage-reference#capacity-metrics

    This means you are only going to see the capacity changes every 24 hours, therefore your alert frequency would have to be at least 24 hours

    I hope this helps provide you with the information you need. If it does, please make sure to mark the question as answered so it helps other people in future.

    Kind regards

    Alistair
