Monitor and scale a single database in Azure SQL Database using the Azure CLI

  • Artikkel

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 don't have an Azure subscription, create an Azure free account before you begin.

Prerequisites

Sample script

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'

For more information, see set active subscription or log in interactively

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

Tip

Use az sql db op list to get a list of operations performed on the database, and use az sql db op cancel to cancel an update operation on the database.

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
