Having set up system and performance alerting, it is now time to test those darn alerts to make sure they work! Alerting can notify a operator via email, paging, or a net send messages. Now adays, most people have a smart phone, not an old fashion pager. Therefore, I usually create a Active Directory group that has both the regular company email of the DBA group and their cell phone eqivalents which are usually the phone number @ provider name dot com. Today, I am going to talk about two…

Performance Alerts
Today, I am going to talk about setting up performance alerts so that you can notified when a server has issues. Basically, there are two types of performance alerts, SQL Server and WMI. I am going to use the sp_add_category system procedure to define a peformance category.

-- Add a custom category for alerts EXEC msdb.dbo.sp_add_category @class=N'ALERT', @type=N'NONE', @name=N'[Alert By Performance]' ; GO -- Show Alert categoryes EXEC msdb.dbo.sp_help_category @class=N'ALERT' GO |
The sp_add_alert stored procedure is used to create the alert and the sp_add_notification stored procedure is used to associate the alert with an operator. This process is used below to show examples of both SQL and WMI performance alerts. The first type…
System Alerts
This article assumes that you configured both database mail and system operators. Please see my previous articles if you have not done these tasks already. Today, I am going to talk about setting up alerts for system error messages that might occur with your SQL server database. Since alerts have been around for a long time, most of this information is backward compatible with older software versions. The database engine defines the importance of an error messages with a severity level. Low importance errors are defined by levels 0 to…
Defining Operators
SQL Server supports the notification of administrators through operators. Operators are aliases for users or groups that can receive notifications when jobs complete or alerts have been raised. Each SQL Server instance can have its own set of defined operators. Today, I am going to walk you thru the following tasks in Transaction SQL. Adding an operator Updating an operator Deleting an operator Defining a fail-safe operator To define an operator, one needs to know the email address of the user and what time he is responsible for the SQL…
Database Mail – Part 1
Database Mail is an enterprise solution for sending e-mail messages from the SQL Server Database Engine. It is very important to configure mail on any server that you manage. Error and performance alerting as well as SQL agent job outcomes depend upon this service for notifications. I am going to copy a paragraph directly from Microsoft TechNet since I can not say it in any better in my own words. Database Mail is designed on a queued architecture that uses service broker technologies. When users execute sp_send_dbmail, the stored procedure…
