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

The AppDynamics Controller is instrumented by an internal, out-of-the-box, AppDynamics Java agent that monitors the performance and health of the Controller itself1. To access the information provided by the internal agent, you need to log in to the Controller UI with the following credentials2:

• Account = system
• Username = root
• Password =

The system account is a special account that is used only for internal monitoring and troubleshooting purposes. It is not visible in the normal Controller UI and requires a special URL to access it2. The root user is the default administrator user for the system account and has the same password as the admin user for the customer1 account3. References: Controller Self-Monitoring, Monitoring a Controller Using the Internal Monitoring Agent, Controller Accounts

According to the Cisco AppDynamics Professional Implementer (CAPI) documents, when updating the Database Agent, you need to follow these steps12:

• Stop the agent as described for your specific installation in Start and Stop the Database Agent.
• Make a copy of the existing agent directory, . Backing up allows you to revert to the previous agent installation if you need to. You can also copy over the controller-info.xml configuration file to the new installation to ensure the agent configuration is maintained.
• Install the Database Agent as described for your specific installation in Administer the Database Agent.
• Copy the \conf\controller-info.xml file to the new installation directory, \conf. To ensure the agent configuration is maintained, copy the \conf\controller-info.xml file to the new installation directory, \conf.
• Start the new agent. See Start and Stop the Database Agent.
• Verify the Database Agent Installation. See Verify the Database Agent Installation.

Therefore, the correct statements are:

• The Database Agent must be stopped and restarted during the upgrade. (A)
• Controller-info.xml is the only file that needs to be migrated from the previous agent to the new agent. (D)

The incorrect statements are:

• If the agent is moved to a new location during the upgrade, the AppDynamics Controller must be reconfigured to reference the new location of the agent. (B) This is not true because the controller-info.xml file contains the information about the Controller host, port, account name, access key, and SSL settings. As long as this file is copied to the new agent location, the Controller does not need to be reconfigured.
• All data collectors created from the previous agent must be migrated to the new agent. © This is not true because the data collectors are configured on the Controller UI, not on the agent. The agent collects the metrics from the databases and sends them to the Controller. The data collectors do not need to be migrated to the new agent.
• After the Database Agent is upgraded, the AppDynamics Controller must be restarted. (E) This is not true because the Controller does not depend on the agent version. The agent and the Controller are compatible as long as they meet the Agent and Controller Compatibility requirements.

The user under which the JVM runs must have write privileges to the conf and logs directories in the Java Agent home. This is because the conf directory contains the agent configuration files, such as controller-info.xml and agent-config.xml, which may need to be modified or updated by the user. The logs directory contains the agent log files, such as agent.log and agent-errors.log, which are generated by the agent and may need to be accessed or rotated by the user. The user can install the agent as the same user that owns the JVM or as an administrator on the host machine. The user can restrict the remaining contents of the agent directory, such as the lib and bin directories, to read-only access12. References: Install the Java Agent, Java Agent fails to start
