Creating a User-Defined Event

You can create user-defined events if you want to monitor events other than events that are predefined by SQL Server. You can also assign a severity level to each user-defined event.


When using SQL Server Management Studio, select the Write to Windows application event log option for each user-defined event message, to ensure that the messages are logged. By default, user-defined messages of severity lower than 19 are not sent to the Microsoft Windows application log when they occur. User-defined messages of severity lower than 19 therefore do not trigger SQL Server Agent alerts.

User-defined events must have a unique message number. Message numbers for a user-defined event must be greater than 50,000. You can define messages for the event in multiple languages. However, an En-US error message must exist before messages in other languages can be added.

If you administer a multiple-language SQL Server environment, create user-defined messages in each of the languages that are supported. For example, if you are creating a new event message to be used on both an English and a German server, use the same message number and severity for both, but assign a different language to each.

The following tasks provide information about how to create user-defined events and alerts that respond to them:
