When monitoring Microsoft SQL Server, the agent used a query variant intended for Azure SQL for every deployment. On standard (non-Azure) SQL Server this could determine the instance name incorrectly. For example, a default instance that had a FileStream share configured was reported incorrectly under that name, so instance verification failed and the instance was not monitored as expected.
Starting with this release, the agent selects the query variant appropriately. Instance names are now determined consistently and correctly for either SQL Server instances or Azure SQL.
