AppDynamics recommends that you terminate SSL connections from agents at a reverse proxy or a load balancer in front of the Controller, rather than at the Controller itself. This improves the performance and scalability of the Controller by offloading the SSL processing to the proxy or load balancer. It also simplifies the configuration and management of SSL certificates and truststores. To enable this option, you need to configure the proxy or load balancer to accept SSL connections from agents and forward them to the Controller using HTTP. You also need to configure the agents to use SSL and point to the proxy or load balancer host and port. See Enable SSL for the Java Agent for an example. References: Agent-to-Controller Connections and Enable SSL and SSH for Database Agent Communications in the AppDynamics documentation.

The EUM Server is the on-premises version of the EUM Cloud that receives, processes, and stores data from EUM agents. For production installation, AppDynamics recommends that the EUM Server and the Controller sit on different hosts, and the EUM Server hosts its own MySQL instance. This improves the scalability and performance of both components. Moreover, AppDynamics strongly recommends that SSL traffic from agents to the EUM Server is terminated at a reverse proxy that sits in front of the EUM Server in the network path, and forwards connections to the EUM Server using HTTP. This relieves the SSL processing load from the EUM Server, simplifies the certificate management, and enhances the security by isolating the EUM Server from the external Internet. Therefore, the best implementation mode for deploying an EUM Server with reverse proxy in a production environment is option D. References: EUM Server Deployment, Install a Production EUMServer, Reverse Proxy configuration for EUM, and Browser EUM installation in the AppDynamics documentation and community.

The Machine Agent REST API allows you to create custom events that can be used for various purposes in AppDynamics. Some of the reasons you would create custom events using this API are12:

• To create an event to track application deployment. You can use the API to send a custom event that marks the start and end of an application deployment process. This can help you monitor the impact of the deployment on the application performance and availability, as well as correlate any issues or anomalies with the deployment event.
• To create an event to be displayed along with Time Series data in a custom dashboard. You can use the API to send a custom event that contains any relevant information or context that you want to display in a custom dashboard. For example, you can send a custom event that contains the details of a configuration change, a maintenance window, a business transaction, or a user action. You can then use the custom dashboard to visualize the custom event data along with the Time Series data for the metrics you are interested in.
• To create an event to be used to trigger a health rule violation. You can use the API to send a custom event that contains a metric value that you want to use as a condition for a health rule. For example, you can send a custom event that contains the CPU utilization of a machine, and then create a health rule that evaluates the CPU utilization metric and triggers a violation if it exceeds a certain threshold. You can then use the health rule violation to generate alerts, notifications, or remediation actions. References: Machine Agent HTTP Listener, Create Custom Events
