Within the SQL Azure Management Portal, customers can check their service usage with the help of various graphs. One of these graphs is the SQL Azure Database Query Usage (CPU) graph, which provides information on the amount of execution time for all queries running on a SQL Azure database over a trailing three month period.
In some cases, this graph was not rendering properly for customers, displaying an error message instead. This error was purely an issue with the portal and not with the underlying SQL Azure databases. We have removed the graph from the management portal, and are looking for alternative ways to surface the same data in a reliable and stable manner. We do apologize for any inconvenience this change has caused.
