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

To create a user group in AppDynamics, you need to go to Settings > Administration > Groups. A user group is a collection of users who share the same roles and privileges. You can use user groups to manage user access and permissions more easily. You can add, edit, delete, or duplicate user groups from the Groups tab on the Administration page.

According to theManage Users and Groups - AppDynamics, the following steps are required to create a user group:

Click the Add button on the Groups tab.

Enter a name and description for the group.

Select one or more roles for the group from the Available Roles list. You can also create a new role by clicking the Add Role button.

Click Save.

Therefore,D(Settings > Administration > Groups) is the correct answer.Reference:

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.

Before creating a new database collector, you need to perform the following actions:

Verify the database connection details. You need to provide the host, port, database name, and credentials for the database that you want to monitor.You also need to select the database type and the collector type1

Create a database user and set user permissions. You need to create a database user with the minimum required permissions to access the database and run the queries that the Database Agent needs.You can use the scripts provided by AppDynamics to create the user and grant the permissions2

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 theOverview 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) andC(Top Leaked Connections) are two stats that are available in Database Visibility.Reference:

Percentile metrics are a way to measure the distribution of response times for a Business Transaction. They show the value below which a certain percentage of measurements fall. For example, the 50th percentile metric shows the median response time, and the 99th percentile metric shows the worst-case response time for 99% of the transactions. To enable percentile metrics, you need to go to Configuration > Slow Transaction Thresholds and indicate 5 whole numbers between 1 and 99 as Percentiles to Collect. You can then view the percentile metrics in the Metric Browser under Business Transaction Performance > Business Transactions > <Application Name> > <Business Transaction Name> > Percentiles.

The Policy Test Bench gives administrators the ability to test and debug policy execution. It allows you to simulate events and see how the policies and actions respond to them.You can also view the policy execution logs and troubleshoot any issues1Reference:1: Policy Test Bench

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.Reference:

When you assign users to a group in AppDynamics, you can manage their permissions and access levels more easily. A group is a collection of users who share the same roles and privileges. A role is a set of permissions that define what actions a user can perform on the Controller UI or the Events Service.

According to theSystem Configuration Guide for Cisco Unified Communications Manager - User Management, the following statement is true about assigning users to a group:

When you add a role to a group, every user in the group is assigned that role: This means that the users in the group inherit the permissions of the role that you add to the group. For example, if you add the Administrator role to a group, then all the users in that group can perform administrative tasks on the Controller UI or the Events Service.

The other statements are false because:

When you assign a user to a group, they can only have the roles assigned to that group: This is not true because a user can belong to multiple groups and have multiple roles. For example, a user can be in both the Administrator and the Operator groups and have the permissions of both roles.

You can list all users in a group that are logged into AppDynamics: This is not true because there is no such feature in AppDynamics that allows you to see the login status of the users in a group. You can only see the list of users and groups in the User Management page of the Controller UI or the Events Service.

When the user logs in they can log in with the group credentials: This is not true because a user cannot log in with the group credentials. A user can only log in with their own username and password. The group credentials are not used for authentication, but for authorization.

Therefore,D(When you add a role to a group, every user in the group is assigned that role) is the correct answer.Reference:
