Wait Type XE_BUFFERMGR_ALLPROCESSED_EVENT

The wait type XE_BUFFERMGR_ALLPROCESSED_EVENT is ranked #49 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.


A SQL Server XE_BUFFERMGR_ALLPROCESSED_EVENT wait type occurs when a task is waiting for an Extended Events (XE) buffer to be fully processed by the XE buffer manager.

Extended Events is a high-performance event-handling system in SQL Server that allows users to collect and analyze data about server operations. The XE buffer manager is responsible for managing the in-memory buffers that hold the collected event data. When the buffers are full, the XE buffer manager processes the event data and writes it to the target, such as a file or a ring buffer.

A task that is waiting for an XE buffer to be fully processed will experience an XE_BUFFERMGR_ALLPROCESSED_EVENT wait. This wait type is typically not a cause for concern, as it simply indicates that the task is waiting for the XE buffer manager to finish processing the event data.

However, if a task is experiencing excessive XE_BUFFERMGR_ALLPROCESSED_EVENT waits, it could be a sign of a performance issue with the XE buffer manager. This could be due to a high volume of event data, which could potentially cause the buffers to fill up more quickly and require more frequent processing by the XE buffer manager.

To troubleshoot XE_BUFFERMGR_ALLPROCESSED_EVENT wait types, you can use the Database Health Monitor to track the XE buffer manager activity and identify any potential bottlenecks. You can also use the Extended Events Manager to view the current event data and see which events are being collected and processed.

In summary, a SQL Server XE_BUFFERMGR_ALLPROCESSED_EVENT wait type occurs when a task is waiting for an Extended Events buffer to be fully processed by the XE buffer manager. This wait type is normal and expected, but if excessive, it can indicate a performance issue with the XE buffer manager. To troubleshoot XE_BUFFERMGR_ALLPROCESSED_EVENT waits, you can use the Database Health Monitor and Extended Events Manager to track XE buffer manager activity and view collected event data.
