The Server Waits view allows you to see all of the waits affecting server= performance. By correlating the areas of the SQL Server instance that= are waiting with other statistics, it is possible to narrow down possible = causes of the waits. All waits occurring on your system are displayed in a = graph that shows the time the wait happened and the length of time it took = for the wait to clear. You can filter the graph by the wait type to view ho= w a particular wait is affecting your server. Below the graph, SQL Diagnost= ic Manager displays a table that includes the wait category, wait type, len= gth of time the wait took to clear, total wait time for all the collected w= ait types, and a definition of the wait type.
Server= waits are always collected. History mode for this view is available. =
