A group can contain multiple roles, which means that the users in the group inherit the permissions of all the roles assigned to the group.For example, you can create a group that has both the Administrator and the Analytics Administrator roles, and the users in that group can perform both the administration and the analytics tasks1Reference:1:Roles and Permissions

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 theServer 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.Reference:

Health rules are the criteria that AppDynamics uses to evaluate the performance and availability of your applications and their components. Health rules can trigger alerts and actions when the conditions are violated or cleared. Events are the occurrences that AppDynamics records when something significant happens in your monitored environment, such as a health rule violation, a policy execution, a deployment, or a custom event.

According to theHealth Rules - AppDynamics, the following two ways can help you see the current status of health rules and events of the business process:

Set up a policy to send an email or text when a health rule status changes: This way, you can get notified in real time when a health rule condition is met or cleared, and take appropriate actions to resolve or prevent issues. You can configure policies to send emails, texts, or other notifications to specific recipients or groups, and include relevant information such as the health rule name, the affected entity, the severity level, and the time range.

Create a dashboard with health and events widgets displayed: This way, you can visualize the health and performance of your applications and their components in a single view, and drill down to the details of each health rule or event. You can create custom dashboards with various widgets that show the health status, the event list, the event summary, the event correlation, and the event timeline of your applications and their components.

Therefore,A(Set up a policy to send an email or text when a health rule status changes) andD(Create a dashboard with health and events widgets displayed) are two ways that can help you see the current status of health rules and events of the business process.Reference:

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

One possible reason why the host does not appear in the Tiers and Nodes view and there are no metrics in the Metric Browser is that the license count for that agent type has been exceeded. You can check the license usage and availability by going to Settings > License in the Controller UI.If the license count is exceeded, you can either purchase more licenses or deactivate some agents to free up the license slots12Reference:1:License Rules and Restrictions2:Manage Licenses

The UniqueHostID agent property is recommended to be used when the machine agent is with multiple app agents on the same machine or when the machine agent is with an app agent on the same machine. This property allows you to specify a unique identifier for the host machine that overrides the default hostname resolution.This helps to avoid conflicts or confusion when multiple agents are running on the same host or when the hostname is not consistent across different agents1Reference:1:How are you able to associate the machine agent with application

According to the Data Collectors document1, a data collector is a configuration that captures application data from a method invocation or an HTTP request. A data collector is associated with a specific method signature or an HTTP parameter name. Therefore, if a new class and method have been deployed to the application, or a new method parameter has been added to an instrumented class, the existing data collector may not match the new code and may need to be updated. However, if the business transaction has been deprecated, or a new HTTP parameter has been added to an existing business transaction, the existing data collector may still work as expected, unless the data collector is specifically configured to filter by the business transaction name or the HTTP parameter value.Reference:

Data Collectors

Business Transaction metrics are the key performance indicators that measure the health and performance of your applications. They include metrics such as average response time, calls per minute, errors per minute, and so on. You can use various types of performance degradation analysis to identify and troubleshoot the root causes of performance issues using Business Transaction metrics.

According to theTroubleshoot Business Transactions - AppDynamics, the following types of performance degradation analysis are used with Business Transaction metrics:

Correlation Analysis: This type of analysis helps you to find the correlation between different metrics and events that may affect the performance of your Business Transactions. For example, you can use the correlation analysis to see how the response time of a Business Transaction is related to the CPU utilization of a node, or how the error rate of a Business Transaction is related to the number of slow database calls.

Remote Services Analysis: This type of analysis helps you to understand how the performance of your Business Transactions is impacted by the calls to remote services, such as databases, web services, message queues, and so on. For example, you can use the remote services analysis to see the response time, call count, error count, and wait time of each remote service call, and drill down to the details of each call.

Compare Releases: This type of analysis helps you to compare the performance of your Business Transactions across different releases of your application. For example, you can use the compare releases analysis to see how the response time, error rate, and throughput of your Business Transactions have changed after a new deployment, and identify any performance regressions or improvements.

Therefore,A(Correlation Analysis),B(Remote Services Analysis), andE(Compare Releases) are three types of performance degradation analysis that are used with Business Transaction metrics.Reference:

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.
