User-Configurable Event Class

[!INCLUDE SQL Server Azure SQL Database Azure SQL Managed Instance] Use the User-Configurable event category to monitor user-defined events. Create user-defined event classes to monitor events that cannot be monitored by the system-supplied event classes in other event categories. For example, a user-defined event can be created to monitor the progress of the application you are testing. As the application runs, it can generate events at predefined points, allowing you to determine the current execution point in your application.

User-Configurable Event Class Data Columns

Data column name	Data type	Description	Column ID	Filterable
ApplicationName	nvarchar	Name of the client application that created the connection to an instance of [!INCLUDEssNoVersion]. This column is populated with the values passed by the application rather than the displayed name of the program.	10	Yes
BinaryData	image	Binary value dependent on the event class captured in the trace.	2	Yes
ClientProcessID	int	ID assigned by the host computer to the process where the client application is running. This data column is populated if the client provides the client process ID.	9	Yes
DatabaseID	int	ID of the database specified by the USE database statement or the default database if no USE database statement has been issued for a given instance. [!INCLUDEssSqlProfiler] displays the name of the database if the ServerName data column is captured in the trace and the server is available. Determine the value for a database by using the DB_ID function.	3	Yes
DatabaseName	nvarchar	Name of the database in which the user statement is running.	35	Yes
EventClass	int	Type of event = 82-91.	27	No
EventSequence	int	The sequence of a given event within the request.	51	No
GroupID	int	ID of the workload group where the SQL Trace event fires.	66	Yes
HostName	nvarchar	Name of the computer on which the client is running. This data column is populated if the client provides the host name. To determine the host name, use the HOST_NAME function.	8	Yes
IsSystem	int	Indicates whether the event occurred on a system process or a user process. 1 = system, 0 = user.	60	Yes
LoginName	nvarchar	Name of the login of the user (either [!INCLUDEssNoVersion] security login or the [!INCLUDEmsCoName] Windows login credentials in the form of DOMAIN\username).	11	Yes
LoginSid	image	Security identifier (SID) of the logged-in user. You can find this information in the sys.server_principals catalog view. Each SID is unique for each login in the server.	41	Yes

NTUserName	nvarchar	Windows user name.	6	Yes
RequestID	int	The ID of the request containing the statement.	49	Yes
SessionLoginName	nvarchar	Login name of the user who originated the session. For example, if you connect to [!INCLUDEssNoVersion] using Login1 and execute a statement as Login2, SessionLoginName shows Login1 and LoginName shows Login2. This column displays both [!INCLUDEssNoVersion] and Windows logins.	64	Yes
SPID	int	ID of the session on which the event occurred.	12	Yes
StartTime	datetime	Time at which the event started, if available.	14	Yes
