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 .
You should run the Disk Statistics report to analyze the disk activity such as work files per minute or page read/writes per second.
Most values on the Disk Statistics report correlate with the related SQL Server metric. However, some metric values represent averages over time. Likewise, a few metric values are based on performance algorithms that use multiple statistics to calculate a more accurate metric.
