Capacity planning is the process of estimating and allocating the resources needed to meet the current and future demands of an application. For a regionally partitioned application, where different users and organizations are assigned to different databases based on their location, capacity planning requires that the administrator monitors the number of users and orgs mapped to each database and ensures that they do not exceed the available resources.

According to the AppDynamics Analytics - AppDynamics, one way to meet this requirement is to schedule an analytics query to check and report on the result periodically. An analytics query is a SQL-like query that allows you to analyze and visualize the data collected by AppDynamics, such as business transactions, logs, metrics, events, and custom data. You can use analytics queries to create dashboards, widgets, reports, and alerts that provide insights into the performance and behavior of your applications and their components.

To schedule an analytics query to check and report on the number of users and orgs mapped to a database, the administrator can follow these steps:

• Go to Analytics > Search.
• Select the data source that contains the user and org information, such as Business Transactions, Logs, or Custom Data.
• Enter the query that counts the number of users and orgs for each database, such as SELECT database, COUNT(DISTINCT user), COUNT(DISTINCT org) FROM data_source GROUP BY database.
• Click the Save button and enter a name and description for the query.
• Click the Schedule button and select the frequency, time range, and recipients for the query execution and report delivery.
• Click Save.

Therefore, A (Schedule an analytics query to check and report on the result periodically) is the correct answer. References:

An exception in AppDynamics is a code-level event that indicates a problem or abnormality in the execution of a business transaction. AppDynamics captures and presents information on exceptions in the monitored environment, and allows you to configure the rules and criteria for detecting and reporting exceptions.

According to the Errors and Exceptions - AppDynamics, the following two types of events would be marked as an exception in AppDynamics:

• A custom-configured error method and error message: This is a type of event that you can define as an exception based on a specific method and message that indicate an error condition in your application code. You can configure the error detection rules to mark a business transaction as an error and capture the exception information when such a method and message are encountered. For example, you can configure a rule to mark a business transaction as an error and capture the exception when the method com.example.MyClass.myMethod returns the message Invalid input.
• Any message that is logged with a severity of Error or Fatal: This is a type of event that AppDynamics automatically detects as an exception based on the log messages that are generated by your application code. AppDynamics scans the log messages for the keywords Error or Fatal, and marks the business transaction as an error and captures the exception information when such a message is found. For example, AppDynamics will mark a business transaction as an error and capture the exception when the log message contains Error: Null pointer exception.

Therefore, B (a custom-configured error method and error message) and C (any message that is logged with a severity of Error or Fatal) are two types of events that would be marked as an exception in AppDynamics. References:

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 the Health 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) and D (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. References:

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 the Metrics - 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 canadd 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) and D (the Metric Browser) are two places where you would find metrics to be added to a custom dashboard. References:

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.

Two types of information that can be shared without an AppDynamics login are Flow Map and Custom Dashboards. Flow Map is a graphical representation of the application topology, showing the interactions between the tiers, nodes, backends, and remote services. CustomDashboards are user-defined views of the application performance data, metrics, and events. You can share these types of information by generating a shareable link from the Controller UI, which can be accessed by anyone who has the link, without requiring a login12 References: 1: Share a Flow Map 2: Share a Custom 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:

According to the Install the Standalone Machine Agent document1, the machine agent is a standalone Java program that collects performance statistics about your environment. It can be deployed on any machine that hosts application servers, database servers, messaging servers, Web servers, etc. However, the machine agent does not start collecting metrics as soon as it is installed. You need to start the machine agent manually or configure it to run as a service or a daemon. Therefore, the correct answer is D. The machine agent does not require an app agent to collect metrics, nor does it run with the monitored application. These are false statements. References:

• Install the Standalone Machine Agent

To alert the operations team that a cloud-based application has provisioned a new instance of a JVM, an administrator should create a policy trigger for Discovery > New Node Discovered. This policy trigger will fire an event when a new node is discovered by the AppDynamics Controller, either by auto-discovery or manual registration. The event will contain information such as the node name, tier name, application name, and agent type. The administrator can then configure an action to send an email, SMS, or custom notification to the operations team with the event details. Alternatively, the administrator can also use the built-in alerting feature of the cloud provider to notify the operations team of the new instance creation.

Remote Services metrics are the metrics that show the performance and behavior of the external systems that an application interacts with, such as web services, databases, message queues, etc. An AppDynamics administrator can use two locations to view Remote Services metrics: the Tier Dashboard and the Exit Point Metrics. The Tier Dashboard shows the flow map of a tier and its downstream dependencies, including the remote services that the tier calls. The administrator can click on any remote service node on the flow map to see the metrics such as average response time, calls per minute, errors per minute, etc. The Exit Point Metrics show the metrics for all the exit points (remote service calls) of an application, grouped by type, such as HTTP, JDBC, JMS, etc. The administrator can drill down to see the metrics for each exit point, such as the backend name, the tier name, the business transaction name, etc.

According to the Upgrade the Java Agent document1, one of the reasons to upgrade AppDynamics agents is to resolve agent issues, such as bugs, performance problems, or compatibility issues withthe Controller or the monitored application. Another reason to upgrade AppDynamics agents is to take advantage of new features, such as enhanced metrics, dashboards, alerts, or integrations, that are introduced in newer agent versions. Therefore, the correct answer is A and D. Database issues and application upgrade are not directly related to the agent upgrade, unless they affect the agent functionality or compatibility. References:

• Upgrade the Java Agent

To create a user in the web user interface, you need to go to Settings > Groups and Roles > Create User. This option allows you to add a new user account and assign it to one or more groups. You can also specify the user’s name, email, password, and authentication method1 References: 1: Create Users

The main benefit of defining Database Collectors is that you can see which applications are calling a database and how they impact the database performance. Database Collectors enable the Database Agent to collect data from your database instances and database servers, such as metrics, queries, sessions, wait states, and more1 You can also link a database on the application flow maps to a database instance monitored by Database Visibility, which allows you to see the correlation between the application and the database2 References: 1: Add Database Collectors 2: [Link a Database on the Application Flow Map to a Database Instance Monitored by Database Visibility]

The Mark Business Transaction as Error checkbox under Configuration > Instrumentation > Error Detection allows you to control whether a business transaction is reported as an error or not. If you clear this checkbox, the business transaction will not be marked as an error and will not affect the error count metrics.

According to the Error Detection: Mark Business Transaction as Error - AppDynamics, the following statements are true when you clear this checkbox:

• The transaction is included in Response Time metrics: This means that the transaction will still contribute to the response time metric, which measures the average time it takes for a request to be completed by AppDynamics. However, it will not affect other response time metrics, such as First Response Time or Average Time to First Byte.
• The transaction is added to error count metrics: This means that the transaction will still count towards the error count metric, which measures the number of transactions that have failed due to errors. However, it will not affect other error count metrics, such as Error Rate or Error Percentage.

Therefore, A (The transaction is included in Response Time metrics) and B (The transaction is added to error count metrics) are true. References:

• Error Detection: Mark Business Transaction as Error - AppDynamics
• Business Transaction - AppDynamics
• Error Detection - AppDynamics

When creating a Health Rule condition, you can use baselines instead of defining a specific threshold for some metrics. Baselines are the dynamic values that represent the normal or expected behavior of a metric, based on the historical data collected by the AppDynamics Cognition Engine. Using baselines can help you account for the variations and seasonality of your application performance, and avoid false positives or negatives. You can use baselines for metrics that have a non-zero average value and a meaningful deviation, such as the overall average response time of a business transaction or an expression containing multiple metrics. You cannot use baselines for metrics that have a zero average value or a negligible deviation, such as the Business Transaction errors per minute or the calls per millisecond.

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

One possible reason why Java APM agents used in a production environment are consistently found to be disabled while no development environments exhibit this behavior is that the production agents are running out of heap memory and crashing. This can happen if the production agents are monitoring a high volume of business transactions, metrics, or snapshots, and the default heap size is not sufficient to handle the load. To resolve this issue, you can enable the heap-storage-monitor-enabled setting on the agent, which allows the agent to monitor its own heap usage and automatically reduce the amount of data it collects when the heap usage reaches a certain threshold. This can help to prevent the agent from running out of memory and crashing. You can also adjust the heap-storage-monitor-threshold setting to specify the percentage of heap usage that triggers the data reduction1. Alternatively, you can also increase the heap space for the agent by using the -Xmx option in the agent startup script, but this may require more resources from the host machine2.

The other options are not valid solutions to resolve this issue. Enabling agent auto-restart in the controller UI will not prevent the agent from crashing due to heap exhaustion, but only restart the agent after it crashes. This may cause data loss and performance degradation3. Decreasing the worker thread count will not affect the heap usage of the agent, but only limit the number of concurrent tasks that the agent can execute. This may reduce the agent throughput and responsiveness.

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 slots12 References: 1: License Rules and Restrictions 2: Manage Licenses
