To examine the Java App agent logs on a host without login access, you can use the Controller UI to request the agent logs. This feature allows you to download the agent logs from the Controller UI without having to access the host machine. You can specify the log level, the time range, and the file size limit for the logs12 References: 1: Request Agent Logs 2: Java Agent Logging

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 the Exit 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. References:

 The default auto-refresh interval for custom dashboards is 120 seconds. This means that the data displayed on the dashboard will be updated every two minutes. The auto-refresh interval can be configured by the dashboard owner or administrator from the dashboard settings. The auto-refresh interval can be set to any value between 15 and 300 seconds, or disabled altogether. The auto-refresh interval applies to all the widgets on the dashboard, unless a widget has its own refresh interval specified.https://docs.appdynamics.com/appd/23.x/latest/en/appdynamics-essentials/dashboards-and-reports/custom-dashboards/create-and-manage-custom-dashboards-and-templates

Server performance data is the information that AppDynamics collects and reports about the health and availability of the servers that host your applications and their components. Server performance data includes metrics such as CPU utilization, memory usage, disk I/O, network traffic, and so on. You can use server performance data to monitor and troubleshoot the performance issues of your servers and applications.

According to the Server Visibility - AppDynamics, the following two reasons are important for the engineer to view and analyze server performance data at this time:

Visualizing application performance during normal operations helps identify when the application performance is abnormal: This means that by comparing the current server performance data with the historical or baseline data, you can detect any anomalies or deviations that may indicate a potential problem or degradation of your application performance. For example, you can use the Server Dashboard to see the current and historical trends of the server metrics, and use the Anomaly Detection feature to identify any outliers or unusual patterns.

Graphs and charts collected at this time are useful for showing application owners the stability of their application: This means that by using the graphical and visual representations of the server performance data, you can communicate and demonstrate the reliability and efficiency of your application to the stakeholders and customers. For example, you can use the Server Health Report to generate a summary of the server health status, availability, and performance over a specified time period, and share it with the application owners.

Therefore, A (Visualizing application performance during normal operations helps identify when the application performance is abnormal) and B (Graphs and charts collected at this time are useful for showing application owners the stability of their application) are two important reasons for the engineer to view and analyze server performance data at this time. References:

A health rule violation canceled warning event or a health rule violation canceled critical event is generated when the health rule processor can no longer accurately assert that the health rule violation continues to violate or that it has ended1. This can happen when the health rule is edited or disabled, among other reasons1. Adding a new condition to the health rule or disabling the health rule are two actions that would trigger a health rule violation canceled event, as they would change the evaluation criteria or stop the evaluation altogether1. Marking the health rule as canceled or removing the health rule from a policy are not valid actions, as they do not affect the health rule configuration or status

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

References: 1: Troubleshoot Agent Connectivity 2

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 application1 References: 1: AppDynamics Agents

The default length of time events can be viewed with full detail before being purged is 7 days, unless archived. Events are records of significant occurrences in the monitored environment, such as errors, exceptions, policy violations, health rule violations, and more. You can view the events in the Controller UI under Events > All Events. You can also archive the events to retain them for longer periods or export them to external systems1 References: 1: Events
