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

To set up AppDynamics Controllers as a high availability pair, you need to meet the following requirements1:

• Passwordless SSH must be configured between the two Controller servers. This allows the Enterprise Console to automate the configuration and administration tasks associated with a highly available deployment on Linux systems.
• Both servers must have the Controller software installed prior to setting up high availability. The Controllers in an HA pair must be equivalent versions, and be in the same data center.
• Both servers must have identical directory structures for the Controller installation. The individual machines in the Controller HA pair need to have an equivalent amount of disk space. References: Prerequisites for High Availability

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
