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

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:

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:

Error configuration is a feature in AppDynamics that allows you to exclude certain types of errors and exceptions from being reported on the dashboard. You can use error configuration to filter out noise and focus on the most relevant and actionable issues.

According to theError Configuration - AppDynamics, the following types of errors and exceptions can be excluded using error configuration:

Database error return codes: These are codes that indicate a problem with the database server, such as 0x80004005 (access denied) or 0x8000005E (access violation). You can exclude these errors from being reported on the dashboard by adding them to the error configuration list.

JavaScript errors: These are errors that occur in the browser due to invalid or malformed JavaScript code, such as syntax errors or reference errors. You can exclude these errors from being reported on the dashboard by adding them to the error configuration list.

Therefore,A(Database error return codes) andC(JavaScript errors) are two options that can be excluded using error configuration.Reference:

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 systems1Reference:1:Events
