Monitor and scale a single database in Azure SQL Database using the Azure CLI
Applies to: Azure SQL Database
This Azure CLI script example scales a single database in Azure SQL Database to a different compute size after querying the size information of the database.
If you prefer to run CLI reference commands locally, install the Azure CLI. If you are running on Windows or macOS, consider running Azure CLI in a Docker container. For more information, see How to run the Azure CLI in a Docker container.
If you're using a local installation, sign in to the Azure CLI by using the az login command. To finish the authentication process, follow the steps displayed in your terminal. For additional sign-in options, see Sign in with the Azure CLI.
When you're prompted, install Azure CLI extensions on first use. For more information about extensions, see Use extensions with the Azure CLI.
Launch Azure Cloud Shell
The Azure Cloud Shell is a free interactive shell that you can use to run the steps in this article. It has common Azure tools preinstalled and configured to use with your account.
To open the Cloud Shell, select Try it from the upper right corner of a code block. You can also launch Cloud Shell in a separate browser tab by going to https://shell.azure.com.
When Cloud Shell opens, verify that Bash is selected for your environment. Subsequent sessions will use Azure CLI in a Bash environment. Select Copy to copy the blocks of code, paste it into the Cloud Shell, and press Enter to run it.
Sign in to Azure
Cloud Shell is automatically authenticated under the initial account signed-in with. Use the following script to sign in using a different subscription, replacing
<Subscription ID> with your Azure Subscription ID. If you don't have an Azure subscription, create an Azure free account before you begin.
subscription="<subscriptionId>" # add subscription here az account set -s $subscription # ...or use 'az login'
Run the script
# Monitor and scale a single database in Azure SQL Database # Variable block let "randomIdentifier=$RANDOM*$RANDOM" location="East US" resourceGroup="msdocs-azuresql-rg-$randomIdentifier" tag="monitor-and-scale-database" server="msdocs-azuresql-server-$randomIdentifier" database="msdocsazuresqldb$randomIdentifier" login="azureuser" password="Pa$$w0rD-$randomIdentifier" echo "Using resource group $resourceGroup with login: $login, password: $password..." echo "Creating $resourceGroup in $location..." az group create --name $resourceGroup --location "$location" --tags $tag echo "Creating $server on $resource..." az sql server create --name $server --resource-group $resourceGroup --location "$location" --admin-user $login --admin-password $password echo "Creating $database on $server..." az sql db create --resource-group $resourceGroup --server $server --name $database --edition GeneralPurpose --family Gen5 --capacity 2 echo "Monitoring size of $database..." az sql db list-usages --name $database --resource-group $resourceGroup --server $server echo "Scaling up $database..." # create command executes update if database already exists az sql db create --resource-group $resourceGroup --server $server --name $database --edition GeneralPurpose --family Gen5 --capacity 4
Clean up resources
Use the following command to remove the resource group and all resources associated with it using the az group delete command - unless you have an ongoing need for these resources. Some of these resources may take a while to create, as well as to delete.
az group delete --name $resourceGroup
This script uses the following commands. Each command in the table links to command-specific documentation.
|az sql server||Server commands.|
|az sql db show-usage||Shows the size usage information for a database.|
