I find wait stats so useful that I’ve got Paul Randal’s SQL Server Wait Statistics (or please tell me where it hurts…) bookmarked and I visit it frequently.
But that gives the total amount of waits for each wait type accumulated since the server was started. And that isn’t ideal when I’m troubleshooting trouble that started recently. No worries, Paul also has another fantastic post Capturing wait statistics for a period of time.
You can also get this from various monitoring tools, as Michael mentions, but if you don’t have such a tool in place, here’s how you can roll your own.
