AppDynamics Monitoring Extensions require a Server Infrastructure & Monitoring (SIM) agent or a Standalone Machine Agent (MA) to report metrics to the AppDynamics Controller. For more details on SIM, check Server Visibility. For more details on MA, check Standalone Machine Agent.
IMPORTANT: AppDynamics Extensions are supported only if there is a single instance of either a MA with APM agents or a SIM agent on a physical host. Multiple instances of MA or SIM on a single physical host is not supported for extensions installation.
In this mode, it is imperative to purchase the Server Visibility license and provide the sim-enabled flag to the agent. It can be provided as a JVM argument to the MA or can be specified in the controller-info.xml. For more details, refer to Enable Server Visibility.
In this case, the agent’s metrics will be reported in the Metric Browser under the "Servers" tab in the controller as shown below :
1. When using the APM MA installation scenario, the application name, tier name, and node name should not be provided to the MA as it will piggyback on the APM Agents running on the same server. In this case, the agent’s metrics will be reported under the Metric Browser of all the APM apps.
