Health Rules are the rules that define the normal or expected behavior of your application, such as the response time, error rate, or CPU utilization of a business transaction, tier, node, or backend. You can create health rules to monitor the performance and availability of your application and its components. When a health rule is violated, it changes the status of the corresponding key performance indicator (KPI) from normal to warning or critical, depending on the severity of the violation. The status change is also represented as an event in the AppDynamics Controller UI, which can trigger alerts, policies, and actions. You can view the health rule events in the Events tab of the application dashboard, or in the Health tab of the entity dashboard.

When you have a custom dashboard that has only one widget, you can delete that widget by clicking the Delete Widget button on the widget properties panel. This will remove the widget from the dashboard, but it will not delete the dashboard itself. You can still view and edit the dashboard from the Controller UI or the Events Service.

According to the Create and Manage Custom Dashboards and Templates - AppDynamics, when you delete a widget from a custom dashboard, AppDynamics does not create a blank widget because empty dashboards are not allowed. Instead, it preserves the existing widgets on the dashboard and displays them in a single row.

Therefore, B (The widget is deleted, but an empty custom dashboard is maintained) is true. References:

Infrastructure monitoring is the feature in AppDynamics that allows you to monitor and troubleshoot the health and availability of the servers that host your applications and their components. Infrastructure monitoring includes metrics such as CPU utilization, memory usage, disk I/O, network traffic, and so on. You can use infrastructure monitoring to detect and resolve the problems that affect the performance and reliability of your servers and applications.

According to the Server Visibility - AppDynamics, the following kind of problem is detected with infrastructure monitoring:

• Process level problems: These are the problems that occur at the process level of the server, such as high CPU consumption, memory leaks, excessive disk I/O, or network congestion. You can use infrastructure monitoring to identify the processes that are consuming the most resources, and drill down to the details of each process, such as the command line, the environment variables, the open files, the threads, and the sockets. You can also use infrastructure monitoring to correlate the process level problems with the application performance problems, such as slow response time, high error rate, or low throughput.

Therefore, E (process level problems) is the correct answer. References:
