Microsoft Azure Storage Analytics generates logs to trace requests, analyze usage trends. Storage Analytics logs contain detailed information for authenticated requests and successful anonymous requests to a storage service. Logs are stored in block blobs in a container named $logs which is automatically created when you enable analytics on a given storage account. It is very useful to enable Storage analytics to diagnose issues with storage accounts.
