The Server Statistics report lets you analyze and compare performance trends across two SQL Server instances.
You can select a Chart Type from the following drop-down list to be displayed in the report: Response Time, % CPU Usage, Memory Usage (GB), and % Disk Busy. The Master Metrics table shows the comparison of the selected instances for all the mentioned metrics over a specified period of time.
When to run this report
You should run the Server Statistics report when you want to trend key performance metrics over time for one or two specific instances, in response to a known problem or a routine health check. For example, if the same third party application uses two different databases but only one database has reported issues, then comparing their key performance metrics can help you diagnose the issue.
