Usare PowerShell per monitorare e ridimensionare un singolo database SQLUse PowerShell to monitor and scale a single SQL database

Questo esempio di script di PowerShell consente di monitorare le metriche delle prestazioni di un database, ne aumenta le prestazioni a un livello superiore e crea una regola di avviso per una delle metriche delle prestazioni.This PowerShell script example monitors the performance metrics of a database, scales it to a higher performance level, and creates an alert rule on one of the performance metrics.

Questo esempio richiede il modulo Azure PowerShell 4.0 o versioni successive.This sample requires the Azure PowerShell module version 4.0 or later. Eseguire Get-Module -ListAvailable AzureRM per trovare la versione.Run Get-Module -ListAvailable AzureRM to find the version. Se è necessario eseguire l'installazione o l'aggiornamento, vedere come installare il modulo Azure PowerShell.If you need to install or upgrade, see Install Azure PowerShell module.

Eseguire Login-AzureRmAccount per creare una connessione con Azure.Run Login-AzureRmAccount to create a connection with Azure.
