Different ways to Auditing Azure SQL Database and Azure Synapse Analytics

Posted by

The default auditing policy includes the following set of action groups, which audits all the queries and stored procedures executed against the database, as well as successful and failed logins:



  • Azure SQL Database and Azure Synapse Analytics Audit can store 4000 characters of data for character fields in an audit record.
  • Any data beyond the first 4000 characters are truncated and not audited.
  • Enabling auditing on a paused dedicated SQL pool is not possible. 
  • When Auditing is configured to a Log Analytics workspace or to an Event Hubs destination in the Azure portal or PowerShell cmdlet, a Diagnostic Setting is created with SQLSecurityAuditEvents category enabled.

How to Navigate to enable Auditing in Azure SQL Database and Azure Synapse Analytics

  1. Go to the Azure portal.
  2. Navigate to Auditing under the Security heading in your SQL database or SQL server pane.
  3.  View server settings link on the database auditing page to iew or modify the server auditing settings

4. You can either enable auditing at database level –> go to server –> Database –> Auditing ,for that switch Auditing to ON. If server auditing is enabled, the database-configured audit exists side-by-side with the server audit.

5. To enable auditing at Server level go to Server –> Auditing

6. you have multiple options for configuring where audit logs are stored. You can write logs to

  • an Azure storage account,
  • to a Log Analytics workspace for consumption by Azure Monitor logs, or
  • to event hub for consumption using event hub.

Audit to storage destination

To configure writing audit logs to a storage account, select Storage when you get to the Auditing section.

You can use the following two storage authentication types: Managed Identity and Storage Access Keys.


  • The default value for retention period is 0 (unlimited retention). You can change this value by moving the Retention (Days) slider in Advanced properties when configuring the storage account for auditing.
  • If you are deploying from the Azure portal, make sure that the storage account is in the same region as your database and server. If you are deploying through other methods, the storage account can be in any region.
