After you create a model by using the System Center Capacity Planner Model Wizard or refine it by using the Capacity Planner Model Editor, you can run a simulation to get utilization and latency performance data for the deployment. When you run the simulation, the elapsed time of the simulation is displayed and any needed simulation adjustments are listed.
If a simulation adjustment is required, you can click the help link icon to view information that explains what is causing the problem, why it is occurring, and how to correct it. Corrective actions are made by modifying the capacity model in the Model Editor. When the simulation is complete, simulation results are displayed. You can use these results to determine whether resources are over-utilized or whether transactions have high latency. All results are measured against threshold settings that you set on the Threshold settings page of the Simulation Results section in Capacity Planner.
