The most important factor in determining sizing for AppDynamics Controller is the projected metric

load per minute on the Controller. This is because the metric load represents the actual workload on

the Controller, which depends on the nature of the application, the AppDynamics configuration, and

the usage patterns. The number of agents, the type of agents, the number of administrators/end

users, and the number of AppDynamics applications are only rough estimates that can vary greatly

depending on the specific scenario. Therefore, it is recommended to test the performance of the

system in a staging environment and verify the Controller sizing using the metric upload rate before

deploying to production. Reference: Controller System Requirements, Performance and Controller
