Monitoring your SQL database and related tasks is a key aspect of administering a successful database and Microsoft Azure provides robust capabilities for doing so. As an Azure SQL Administrator preparing for your DP-300 exam, understanding how to configure alerts and notifications for database tasks is essential. You can configure alerts and notifications to keep you abreast of changes, anomalies, and actions that need to be taken in the database system.
Configuring Alerts
Alerts in Azure SQL provide instant notifications when specific conditions or exceptions occur in your database. These alerts can be configured based on performance metrics or specific activity logs.
The following are the steps to configure alerts:
- Navigate to the Azure portal, select your SQL database, and then select the Alert Rules button from the left navigation pane.
- Click on New Alert Rule.
- This will open up a configuration window. Here, you will need to fill the correct information such as the metric (CPU percentage, SQL Server connections, etc.), the operator (Greater Than, Less Than, Equal To), and the threshold value.
- Next, you configure the notification details. You could choose to receive an Email or SMS or both.
- Finally, click on OK to save your changes.
Configuring Notifications
Azure SQL also allows administrators to send notifications about specific activities such as database backups, potential security vulnerabilities, or suspicious activities.
Azure SQL Database integrates with Azure’s Action Group feature to facilitate these notifications. Action Groups offer several types of notifications, each tailored to different needs. Here are a few examples:
- Email/SMS/Push/Voice: These notifications allow an alert to be sent via email, pushed to a mobile device, sent via SMS, or even as a voice call.
- Azure Function: If you need to perform an automated response, you can execute an Azure Function in response to an alert.
- Logic App: To orchestrate a complex set of actions in response to an alert, you can execute an Azure Logic App.
- Webhook: To send data to external systems or for manual intervention, you can send data to a webhook.
To set up notifications via action groups, navigate to Monitor > Alerts > Manage Actions and from this window you can create a new action group or manage existing ones.
It’s important to note that, alerts and notifications are the primary means for understanding the health, performance, and activity of your Azure SQL database. They provide key insights in real-time, enabling you to act promptly and maintain optimal database performance.
In conclusion
Configuring alerts and notification on database tasks is a crucial skill for Azure SQL Administrators. It allows administrators to stay informed about the status of their databases and respond swiftly to maintain optimal performance. As an aspiring DP-300 exam candidate, this knowledge is invaluable in managing and administering Microsoft Azure SQL solutions.

Interview Questions
How can alerts in Azure SQL be configured?
Alerts in Azure SQL can be configured through the Azure portal. Go to the database you want to monitor, select “Alerts” under the monitoring section, click on “+ New alert rule”, and set the conditions and actions as desired.
What is the purpose of Alerts in Database tasks?
Alerts are used to notify the user about certain events or conditions, such as performance issues, database capacity, or availability status. This enables pro-active monitoring and management of the database.
How can you be notified when an alert is triggered in Azure SQL Database?
You can configure Azure SQL Database to send an email when an alert is triggered. This is done by setting an action group in the alert rule that includes sending an email.
What services can Azure use to send notifications regarding database tasks?
Azure can use Azure Monitor, Azure Logic Apps, and Azure Functions to send notifications.
What is the role of Azure Monitor in configuring alerts and notifications on database tasks?
Azure Monitor collects, analyzes, and acts on telemetry data from your Azure resources. It can generate alerts when specific events occur or conditions are met, enabling you to identify, troubleshoot, and resolve issues faster.
Can you configure an alert based on a custom log query in Azure Monitor?
Yes, Azure Monitor allows you to write a custom log query and then base an alert on the results of that query.
Can you send alerts to non-Azure systems?
Yes, Azure Monitor can send alerts to ITSM, DevOps, and automation platforms, email directly to users, or invoke a logic app that integrates with systems outside of Azure.
How can you disable an alert in Azure SQL Database?
You can disable an alert by selecting it from the alerts list and disabling it by using the “Disable” button.
What are the basic elements that are required to create an alert in Azure SQL Database?
The basic elements required are a target resource, criteria or conditions for the alert, and an action group to take when the alert is triggered.
