“Application Management” reports execution statistics for user tasks. This section is useful if you use resource limits, or if you plan to tune applications by setting execution attributes and assigning engine affinity. Before making any adjustments to applications, logins, or stored procedures, run sp_sysmon during periods of typical load, and familiarize yourself with the statistics in this section.
