Use CLI to monitor and scale a single SQL database

This Azure CLI script example scales a single Azure SQL database to a different performance level after querying the size information of the database.

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

Launch Azure Cloud Shell

The Azure Cloud Shell is a free Bash shell that you can run directly within the Azure portal. It has the Azure CLI preinstalled and configured to use with your account. Click the Cloud Shell button on the menu in the upper-right of the Azure portal.

Cloud Shell

The button launches an interactive shell that you can use to run all of the steps in this topic:

If you choose to install and use the CLI locally, this topic requires that you are running the Azure CLI version 2.0 or later. Run az --version to find the version. If you need to install or upgrade, see Install Azure CLI 2.0.

Sample script

#!/bin/bash

# Set an admin login and password for your database
export adminlogin=ServerAdmin
export password=ChangeYourAdminPassword1
# the logical server name has to be unique in the system
export servername=server-$RANDOM

# Create a resource group
az group create \
	--name myResourceGroup \
	-location westeurope 

# Create a server
az sql server create \
	--name $servername \
	--resource-group myResourceGroup \
	--location westeurope \
	--admin-user $adminlogin \
	--admin-password $password

# Create a database
az sql db create \
	--resource-group myResourceGroup \
	--server $servername \
	--name mySampleDatabase \
	--service-objective S0

# Monitor database size
az sql db list-usages \
	--name mySampleDatabase \
	--resource-group myResourceGroup \
	--name $servername

# Scale up database to S1 performance level (create command executes update if DB already exists)
az sql db create \
	--resource-group myResourceGroup \
	--server $servername \
	--name mySampleDatabase \
	--service-objective S1

Clean up deployment

After the script sample has been run, the following command can be used to remove the resource group and all resources associated with it.

az group delete --name myResourceGroup

Script explanation

This script uses the following commands. Each command in the table links to command specific documentation.

Command Notes
az group create Creates a resource group in which all resources are stored.
az sql server create Creates a logical server that hosts a database.
az sql db show-usage Shows the size usage information for a database.
az sql db update Updates database properties (such as the service tier or performance level) or moves a database into, out of, or between elastic pools.
az group delete Deletes a resource group including all nested resources.
