I'm not in the same league with you guys as far as what this all means. I apologize for any dumb questions, but is this reporting CURRENT activities or is it a history? If a history, over what time period?
Hey no apologies required!! We are all here to learn and help when we can
As for reporting (current or historial), see below as per Microsoft (http://msdn.microsoft.com/en-us/library/ms179984(v=sql.105).aspx)
"Returns information about all the waits encountered by threads that executed. You can use this aggregated view to diagnose performance issues with SQL Server and also with specific queries and batches"
But threads had to have executed so in a sense it is historical.
Hope this help,
PS. Please continue to ask question regardless as we all learn from them
