500-430 Exam Dumps : Cisco AppDynamics Professional Implementer(CAPI)

The AppDynamics Controller is a Java web application that runs on a GlassFish application server and uses a MySQL database. During the installation of the Controller, two user accounts are created by default:

• The GlassFish asadmin user is the administrative user for the GlassFish server. This user has the authority to start, stop, and configure the GlassFish server and its domains. The default username for this user is admin and the default password is appdynamics. You can change the password for this user after the installation by using the asadmin command-line tool1.
• The customer-specified Controller administrator account is the user account that you provide during the installation wizard. This is the account that you use to access the AppDynamics User Interface (UI) for the first time and perform various tasks such as creating applications, configuring agents, managing users and groups, and so on. You can choose any username and password for this account, but AppDynamics recommends using only ASCII characters. You can also create additional user accounts in the Controller UI after the installation2.

The other options are not user accounts that are created by the Controller installation. The Elastic search root user, the REST API user, and the MySQL appd admin user are user accounts that are used internally by the Controller components and are not exposed to the end user. The OS user that will run the controller is a user account that you need to create on the host machine before the installation, and it is not created by the Controller installation3. References: Controller Installation, Manage Users and Groups, and Update the Root User and Glassfish Admin Passwords in the AppDynamics documentation.

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.

In a hybrid deployment of AppDynamics, where the AppDynamics Controller and Events Service are installed on-premises and the EUM Server is hosted in AppDynamics’ SaaS cloud, the data that is unavailable is the analytics metrics for End-User Monitoring data sets. This is because the analytics metrics require the Events Service to store and process the unstructured data generated by the EUM agents. However, in a hybrid deployment, the EUM Server and the Events Service are not connected, and the EUM Server does not send the EUM data to the Events Service. Therefore, the analytics metrics for EUM data sets, such as browser records, mobile snapshots, network requests, and custom events, are not available in the Controller UI or the Analytics UI1. The other data, such as resource loading times, session information, and browser snapshots, are available in the EUM Server UI, as they are stored and displayed by the EUM Server itself2. References: Hybrid Deployment and EUM Data Sets in the AppDynamics documentation.
