Wait Type SQLTRACE_FILE_BUFFER

The wait type SQLTRACE_FILE_BUFFER is ranked #47 by Stedman Solutions and Database Health Monitor.

Wait statistics, in the context of SQL Server, refer to the amount of time that a query spends waiting to access data in the database. When a client application requests data from the database, the request is placed in a queue and the client application must wait for its turn to access the data. The time that the query spends waiting is called a "wait" and is tracked by SQL Server. This information can be used to identify potential performance bottlenecks and optimize the performance of the database. Wait statistics are commonly used by database administrators to diagnose and troubleshoot performance issues in SQL Server.


One of the common wait types that can occur in SQL Server is the SQLTRACE_FILE_BUFFER wait type. This wait type indicates that a task is waiting to write data to the SQL Trace file buffer.

The SQL Trace facility is used to collect a variety of information about the operation of SQL Server, such as the duration of queries, the resources they use, and any errors that occur. This information can be useful for diagnosing performance issues and troubleshooting problems with the database.

The SQLTRACE_FILE_BUFFER wait type occurs when a task is trying to write data to the SQL Trace file buffer, but the buffer is currently full. In this case, the task must wait until space becomes available in the buffer before it can continue.

The SQLTRACE_FILE_BUFFER wait type is a normal and expected part of the operation of SQL Server, and is typically not something that requires action. However, if you are experiencing a high volume of SQLTRACE_FILE_BUFFER waits, it could be an indication that there is a problem with the configuration of your SQL Trace facility. For example, the size of the file buffer may be set too small, causing it to fill up quickly and causing tasks to wait. In these cases, it may be necessary to adjust the configuration of the SQL Trace facility in order to reduce the number of SQLTRACE_FILE_BUFFER waits.

Overall, the SQLTRACE_FILE_BUFFER wait type is a normal and expected part of the operation of SQL Server. While it is typically not something that requires action, it is important to monitor for high volumes of these waits, as they can indicate potential performance issues with the SQL Trace facility.
