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.https://www.appdynamics.com/product/how-it-works/application-performance-baseline

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]

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.https://university.appdynamics.com/certifications/associate-administrator

According to the Database Visibility Supported Environments document1, Database Visibility can monitor the following databases: PostgreSQL, Cassandra, MongoDB, MySQL, SQL Server, Oracle, Sybase ASE, Sybase IQ, and Couchbase. Therefore, the correct answer is A, B, and D. Derby and DB2 are not supported by Database Visibility. References:

• Database Visibility Supported Environments

To manage Controller security settings, you would need to grant the Security Administrator role to an existing user. The Security Administrator role is a built-in role that allows the user to access and modify the security settings of the Controller, such as encryption, certificates, authentication, authorization, and audit1. The Security Administrator role also inherits the permissions of the Credentials Administrator role, which allows the user to manage the credentials for the Controller and the agents2. The other roles listed do not have the permission to manage Controller security settings. The Administrator role can perform most administrative tasks, but not security-related ones2. The Analytics Administrator role can manage the analytics platform and data, but not theController security3. The Account Owner role can manage the account settings and licenses, but not the Controller security4

Database Visibility provides metrics on the performance of your database and helps troubleshoot performance-related issues. Database Visibility consists of four main components: Database Agent, Collector, Controller, and Events Service (on-premises only). The Database Agent is a standalone Java program that collects performance metrics about your database instances and database servers. The Collector is the process that runs within the Database Agent to collect performance metrics about your database instances and database servers. The Controller is the central interface where you can see all your database instances and database server performance metrics. The Events Service stores high volumes of metric data.

According to the Overview of Database Visibility, the following types of information are sent to the Controller:

• Database-level metrics, such as the number of queries processed and other database statistics
• Names and attributes of all sessions, clients, queries, and other objects on the monitored system

The following types of information are sent to the Events Service:

• Time that each query spends at each wait state
• Individual query statistics for databases that support it
• Information about individual execution plans in databases that support it

Therefore, B (Average Number of Slow Connections) and C (Top Leaked Connections) are two stats that are available in Database Visibility. References:

According to the Widgets document1, there are various types of widgets that can be used to create visual representations of data in custom dashboards and war rooms. Some of the widget types are:

• Flow Map: A flow map widget displays the flow of traffic between different entities, such as applications, tiers, nodes, backends, and so on. You can customize the flow map to show different metrics, filters, and drill-down options.
• iFrame: An iFrame widget allows you to embed an external web page or another dashboard within a custom dashboard. You can specify the URL, height, and width of the iFrame widget.
• Health List: A health list widget displays the health status of different entities, such as applications, tiers, nodes, business transactions, and so on. You can customize the health list to show different metrics, filters, and drill-down options.

Therefore, the correct answer is A, B, and C. Snapshot and Funnel Analysts are not widget types, but features or tools that can be accessed from other widgets or dashboards. References:

• Widgets

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:

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.

By default, the Java Agent enables two Sensitive Data Filters substring: substring “key” and substring “password”. These filters prevent the agent from capturing and sending any data that contains these substrings to the Controller, such as query parameters, HTTP headers, cookies, environment variables, or system properties. This helps to protect sensitive information from being exposed in the Controller UI or reports. You can also add more filters or modify the existing ones by editing the agent configuration file1 References: 1: Filter Sensitive Data
