The sp_sysmon statistics in the summary section can help you determine whether there are any anomalies in resource utilization. If there are, you can investigate further using the detailed report.
This section gives information about:
Whether tasks are switching back and forth between different priority levels
Whether the assigned time that tasks are allowed to run is appropriate
Whether tasks to which you have assigned low priority are getting starved for CPU time
Whether engine bindings with respect to load balancing is correct
Note that “Application Statistics Summary” includes data for system tasks as well as for user tasks. If the summary report indicates a resource issue, but you do not see supporting evidence in the application or application and login information, investigate the sp_sysmon kernel section of the report (“Kernel utilization”).
