The Disk Statistics report lets you view trends for the disk activity of a monitored SQL Server instance over a specified period of time. To successfully monitor OS metrics, make sure that you enable WMI or OLE automation on the monitored instance. Check Show Tabular Data to display results in a single tabular or grid format.

Check Show Baseline to include baseline data points in the Disk Statistics report. For additional information about baseline configuration, see Configure server baseline options.

When to run this report

You should run the Disk Statistics report to analyze the disk activity such as work files per minute or page read/writes per second.
