You can monitor your storage account by collecting metrics for the requests on your services. Metrics are collected to analyze usage and diagnose issues in order to improve performance of all consuming applications.
Transactional information such as ingress/egress, latency, and success percentages is saved for requests and responses on services. Capacity information is also stored to monitor usage. Data in these tables can be accessed using the table service APIs and .Net APIs. The data is read-only and cannot be manipulated or created by the user.
