Why does Azure file/blob storage use table requests

votes

We have an Azure storage account that uses blob and file storage but we seem to be incurring table requests and a few queue requests even though we haven't created any tables or queues. I assume they are to support the file storage upload/download in some way but I wanted to understand how and why to determine accurate usage for both monitoring and billing.

Are you using WebJobs at all? – Matthew Steeples
No, there's nothing else in the subscription at all at the moment. Is it to support stats maybe? – Dan Kennedy
Tables...definitely to store storage analytics data. Not sure about queues. – Gaurav Mantri

As @Gaurav Mantri mentioned, Tables are used to store Azure Storage Analytics metrics. You can find there are multi tables whose name is start with $Metrics.

The amount of storage used by metrics data is also billable. The following actions performed by Storage Analytics are also billable:

  1. Requests to create blobs for logging.
  2. Requests to create table entities for metrics.

You can enable or disable the metrics on Azure portal.

To find why your queue was used, I suggest you enable Queue logs on Diagnostics tab of Azure portal. You will find the detail usage of your queue in following blob.
