The AppDynamics Controller Admin Console lets you configure certain global settings for the

Controller, such as metric retention periods, UI notification triggers, tenancy mode, and accounts in

multi-tenancy mode1. Two of the settings that an administrator can configure from the AppDynamics

Controller Admin Console are:

License allocation: This setting allows you to view and manage the license usage and availability for

your Controller. You can see the total number of licenses, the number of licenses in use, the number

of licenses available, and the license expiration date for each agent type. You can also allocate

licenses to specific applications or accounts, and set license limits and alerts2.

Retention periods: This setting allows you to specify how long the Controller retains the metric data

and the event data for your monitored applications. You can configure the retention periods for

different types of data, such as minute-level metrics, hour-level metrics, day-level metrics,

transaction snapshots, and events. You can also configure the data purge schedule and the data

backup schedule3.
