Create alerts for Azure SQL Database and Azure Synapse Analytics using the Azure portal

Applies to: Azure SQL Database Azure Synapse Analytics


This article shows you how to set up alerts for databases in Azure SQL Database and Azure Synapse Analytics using the Azure portal. Alerts can send you an email or call a web hook when some metric (for example database size or CPU usage) reaches the threshold.


For Azure SQL Managed Instance specific instructions, see Create alerts for Azure SQL Managed Instance.

You can receive an alert based on monitoring metrics for, or events on, your Azure services.

  • Metric values - The alert triggers when the value of a specified metric crosses a threshold you assign in either direction. That is, it triggers both when the condition is first met and then afterwards when that condition is no longer being met.
  • Activity log events - An alert can trigger on every event, or, only when a certain number of events occur.

You can configure an alert to do the following when it triggers:

  • Send email notifications to the service administrator and co-administrators
  • Send email to additional emails that you specify.
  • Call a webhook

You can configure and get information about alert rules using

Create an alert rule on a metric with the Azure portal

  1. In the portal, locate the resource you are interested in monitoring and select it.

  2. Select Alerts in the Monitoring section. The text and icon may vary slightly for different resources.


  3. Select the New alert rule button to open the Create rule page. Create rule

  4. In the Condition section, click Add. Define condition

  5. In the Configure signal logic page, select a signal. Select signal

  6. After selecting a signal, such as CPU percentage, the Configure signal logic page appears. Configure signal logic

  7. On this page, configure that threshold type, operator, aggregation type, threshold value, aggregation granularity, and frequency of evaluation. Then click Done.

  8. On the Create rule, select an existing Action group or create a new group. An action group enables you to define the action to be taken when an alert condition occurs. Define action group

  9. Define a name for the rule, provide an optional description, choose a severity level for the rule, choose whether to enable the rule upon rule creation, and then click Create rule alert to create the metric rule alert.

Within 10 minutes, the alert is active and triggers as previously described.
