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:

The App Server agent configuration GUI allows you to set the configuration for the following agent properties:

• Node-name: This property defines the name of the node that appears in the Controller UI. You can use the GUI to change the node name or use auto-naming rules based on environment variables or system properties1
• Max-business-transactions per node: This property sets the maximum number of business transactions that can be registered on a node. If the number of business transactions exceeds this limit, the agent stops registering new business transactions and reports them as “All Other Traffic”. You can use the GUI to increase or decrease this limit2

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 > > > Percentiles.

To properly configure a database agent from a zip file, you need to provide the following minimum details:

• Controller Host: This is the hostname or IP address of the machine where the Controller is installed. You need to specify this so that the Database Agent can communicate with the Controller and send the collected data1
• Controller Port: This is the port number that the Controller listens on for incoming connections. You need to specify this so that the Database Agent can connect to the Controller using the correct protocol. The default ports are 8090 for HTTP and 8181 for HTTPS for on-premise Controllers, and 80 for HTTP and 443 for HTTPS for SaaS Controllers1
• Account Access Key: This is the key that authenticates the Database Agent with the Controller. You need to specify this so that the Database Agent can register itself with the Controller and access the license. You can find the account access key in the Controller UI under Settings > License > Account1
• Account Name: This is the name of the account that the Database Agent belongs to. You need to specify this so that the Database Agent can associate itself with the correct application and user permissions. You can find the account name in the Controller UI under Settings > License > Account1

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:

To find the information that shows the current application, tier, and node that the agent currently reports to, you can go to View my settings > AppDynamics Agents section in the Controller UI. This section shows you the list of agents that are connected to the Controller, along with their status, version, application, tier, and node names. You can also filter the list by agent type, status, or application1 References: 1: AppDynamics Agents

According to the Actions document1, there are four types of standard controller actions that are available to be created: Notification, Diagnostic, Remediation, and JIRA. Each type of action has different subtypes that perform specific tasks. For example, the Notification type includes Email, SMS, and HTTP Request subtypes, while the Diagnostic type includes Thread Dump, Heap Dump, and Diagnostic Session subtypes. Therefore, the correct answer is D and E, as Email and Thread Dump are subtypes of standard controller actions. Resolve, Close Incident, and Undeploy are not standard controller actions, but they may be custom actions that are created by the user or the administrator. References:

An HTTP Data Collector is a type of data collector that captures data from HTTP requests and responses. It can capture three kinds of data: parameter values, headers, and cookies. Parameter values are the values of the query string or form parameters in the HTTP request. Headers are the key-value pairs that are sent or received as part of the HTTP request or response. Cookies are the small pieces of data that are stored by the browser and sent to the server with each request. An HTTP Data Collector can be configured to capture any of these data types by specifying the name of the parameter, header, or cookie in the data collector settings. The captured data can be used for various purposes, such as adding context to business transactions, creating custom metrics, or triggering health rules.
