Application Performance Monitor is installed during the WhatsUp Gold installation. Your license determines whether the APM plug-in is available in WhatsUp Gold. To update your license for APM, visit the WhatsUp Customer Portal. APM is licensed on a per-component basis. This means that each component that makes up an application instance uses one license, since they are each individual components of the application instance. For more information on APM licensing or to upgrade your license, click Details during the application setup process.
