To confirm that the agent is communicating properly to the controller, you can use the following methods:

Check if data is being written to the agent log in /logs. This indicates that the agent is able to send metrics and events to the controller.You can also look for any errors or warnings in the log file that might indicate a connection issue1

Select Application > Tiers and Nodes > Look for the Node. This shows you the list of nodes that are registered with the controller and their status.You can see if the node is up or down, the agent version, the last reported time, and the machine name2

According to the Cisco AppDynamics Associate Administrator Certification document1, one of the topics covered in the exam is ''Monitor agent performance and connectivity''.To do this, you need to ensure that the application agent can communicate with the controller, which may require SSL configuration if the controller is using SSL2.You also need to check that there are enough licenses available on the controller for the application agent to register and report data3. If the agent is using the wrong application name or does not have enough memory, it may not start at all or may crash, which are different problems from not being able to connect to the controller.Reference:

According to the Actions document1, there are four types of standard controller actions that are available to be created: Notification, Diagnostic, Remediation, and JIRA. Each type of action has different subtypes that perform specific tasks. For example, the Notification type includes Email, SMS, and HTTP Request subtypes, while the Diagnostic type includes Thread Dump, Heap Dump, and Diagnostic Session subtypes. Therefore, the correct answer is D and E, as Email and Thread Dump are subtypes of standard controller actions. Resolve, Close Incident, and Undeploy are not standard controller actions, but they may be custom actions that are created by the user or the administrator.Reference:

Metrics are the numerical values that AppDynamics collects and reports to measure the performance and availability of your applications and their components. You can use metrics to create custom dashboards that display the data that is relevant to your needs and interests.

According to theMetrics - AppDynamics, the following two places are where you would find metrics to be added to a custom dashboard:

The JMX tab on the Node: This tab shows the Java Management Extensions (JMX) metrics that are exposed by the Java Virtual Machine (JVM) or the application server. JMX metrics provide information about the JVM memory, threads, garbage collection, and other aspects of the Java environment. You can add JMX metrics to a custom dashboard by selecting them from the metric browser tree and dragging them to the dashboard canvas.

The Metric Browser: This is a tool that allows you to browse, search, and view all the metrics that are available in AppDynamics. The metric browser shows the metrics in a hierarchical tree structure that reflects the logical organization of your applications and their components. You can add metrics to a custom dashboard by selecting them from the metric browser tree and dragging them to the dashboard canvas.

Therefore,C(the JMX tab on the Node) andD(the Metric Browser) are two places where you would find metrics to be added to a custom dashboard.Reference:

A data collector is used to capture application data in a single business transaction. A data collector is a configuration that specifies what data to capture from a business transaction and how to store it in the AppDynamics Controller or the analytics platform. You can capture data from HTTP requests, method invocations, custom fields, or information points. You can also apply filters and transformations to the captured data. The captured data can be used for various purposes, such as adding context to business transactions, creating custom metrics, triggering health rules, enriching transaction analytics, or creating business journeys. https://university.appdynamics.com/certifications/associate-administrator

To find the information that shows the current application, tier, and node that the agent currently reports to, you can go to View my settings > AppDynamics Agents section in the Controller UI. This section shows you the list of agents that are connected to the Controller, along with their status, version, application, tier, and node names.You can also filter the list by agent type, status, or application1Reference:1:AppDynamics Agents

According to the Java Memory Leaks document1, one of the ways to detect and troubleshoot Java memory leaks is to use the Automatic Leak Detection feature on the Memory tab of the Node Dashboard. This feature captures and analyzes the collections that are actively used and growing in size over time, indicating a potential memory leak. You can also drill down into the leaking collections to see the content summary and the access traces that show the code path and the business transactions that access the collection. Therefore, the correct answer is D. Examining the values on the Server tab, configuring Object Instance Tracking, or verifying and adjusting the Memory Monitoring configuration may not directly reveal the source of the memory leak, but they may provide some useful information or metrics to support the diagnosis.Reference:

To determine and configure the exit call to the database, you need to go to Configuration > Instrumentation > Backend Detection > Java. An exit call is a call from an application component to an external service or system, such as a database, a web service, a message queue, or a cache. A backend is a logical representation of an external service or system that receives exit calls from an application component. AppDynamics automatically detects and identifies common types of backends, such as JDBC, HTTP, JMS, and so on.

According to theExit Point Detection Rules - AppDynamics, the following steps are required to determine and configure the exit call to the database:

Go to Configuration > Instrumentation > Backend Detection > Java.

Select the application and the tier that contains the exit call to the database.

Click the Add button to create a new exit point detection rule.

Enter a name and description for the rule.

Select the type of exit call from the drop-down list, such as JDBC, HTTP, JMS, and so on.

Specify the class and method that make the exit call to the database.

Specify the match criteria for the exit call, such as the URL, the query, the host, the port, and so on.

Click Save.

Therefore,C(Configuration > Instrumentation > Backend Detection > Java) is the correct answer.Reference:

On a custom dashboard, a non-administrator user can view the following types of information:

The company logo: A custom dashboard can display the company logo in the upper left corner of the dashboard. This can help to brand the dashboard and make it more recognizable for the intended audience.The logo can be configured by the dashboard owner or administrator from the dashboard settings1.

The version of the AppDynamics Controller: A custom dashboard can display the version of the AppDynamics Controller in the upper right corner of the dashboard. This can help to identify the Controller that is hosting the dashboard and the features that are available.The version can be configured by the dashboard owner or administrator from the dashboard settings1.

A Timeseries graph: A custom dashboard can display a Timeseries graph widget that shows the trend of a metric over time. This can help to visualize the performance and behavior of the application, server, or database that is being monitored.A Timeseries graph can be configured by the dashboard owner or administrator from the widget settings2.

A non-administrator user cannot view the following types of information on a custom dashboard:

The current weather in Seattle: A custom dashboard cannot display the current weather in Seattle or any other location, as this is not a metric or data point that is reported by AppDynamics agents or the analytics platform.A custom dashboard can only display the data that is collected and stored by AppDynamics2.

The number of AppDynamics licenses consumed: A custom dashboard cannot display the number of AppDynamics licenses consumed, as this is a Controller-level information that is only accessible by the Controller administrator.A custom dashboard can only display the data that is scoped by the dashboard owner's permissions1. https://docs.appdynamics.com/accounts/en/cisco-appdynamics-saas-deployment-user-management/manage-custom-roles-for-cisco-appdynamics/custom-dashboard-permissions
