Create an Alert Using Severity Level

  • Стаття

Applies to: SQL Server Azure SQL Managed Instance

Important

On Azure SQL Managed Instance, most, but not all SQL Server Agent features are currently supported. See Azure SQL Managed Instance T-SQL differences from SQL Server for details.

This topic describes how to create a Microsoft SQL Server Agent alert that is raised when an event of a specific severity level occurs in SQL Server by using SQL Server Management Studio or Transact-SQL.

Before You Begin

Limitations and Restrictions

  • SQL Server Management Studio provides an easy, graphical way to manage the entire alerting system and is the recommended way to configure an alert infrastructure.

  • Events generated with xp_logevent occur in the master database. Therefore, xp_logevent does not trigger an alert unless the @database_name for the alert is 'master' or NULL.

  • Severity levels from 19 through 25 send a SQL Server message to the Microsoft Windows application log and trigger an alert. Events with severity levels less than 19 will trigger alerts only if you have used sp_altermessage, RAISERROR WITH LOG, or xp_logevent to force them to be written to the Windows application log.

Security

Permissions

By default, only members of the sysadmin fixed server role can execute sp_add_alert.

Using SQL Server Management Studio

To create an alert using severity level

  1. In Object Explorer, click the plus sign to expand the server where you want to create an alert using severity level.

  2. Click the plus sign to expand SQL Server Agent.

  3. Right-click Alerts and select New Alert.

  4. In the New Alert dialog box, in the Name box, enter a name for this alert.

  5. In the Type list, select SQL Server event alert.

  6. Under Event alert definition, in the Database name list, select a database to restrict the alert to a specific database.

  7. Under Alerts will be raised based on, click Severity and then select the specific severity that will raise the alert.

  8. Check the box corresponding to Raise alert when message contains check box to restrict the alert to a particular character sequence, and then enter a keyword or character string for the Message text. The maximum number of characters is 100.

  9. Click OK.

Using Transact-SQL

To create an alert using severity level

  1. In Object Explorer, connect to an instance of Database Engine.

  2. On the Standard bar, click New Query.

  3. Copy and paste the following example into the query window and click Execute.

    -- Adds an alert (Test Alert) that notifies the
-- Alert Operator via email when an error with a 
-- severity of 23 is detected.

-- Assumes that the Alert Operator already exists 
-- and that database mail is configured.

USE msdb ;  
GO  

EXEC dbo.sp_add_alert @name=N'Test Alert', 
  @message_id = 0, 
  @severity = 23, 
  @enabled = 1, 
  @include_event_description_in = 1
;
GO

EXEC dbo.sp_add_notification @alert_name=N'Test Alert',
  @operator_name=N'Alert Operator',
  @notification_method=1
;
GO
