Correct Answer: AE
AE

Explanation:

The AppDynamics standalone Machine Agent is a Java program that runs on a host machine and collects hardware and infrastructure metrics, such as CPU, memory, disk, and network usage.

The Machine Agent can also perform additional functions, such as:

Acting as a forwarder for analytics events: The Machine Agent can be configured to forward business transaction, log, browser, mobile, and synthetic events from the application agents to the AppDynamics Events Service, which is a distributed, scalable data store for analytics data. The Machine Agent can also forward custom events from the SDK or API to the Events Service. This allows you to use the AppDynamics Analytics features, such as dashboards, queries, funnels, and metrics, to analyze the performance and behavior of your applications and users12.

Starting an HTTP listener for custom metrics: The Machine Agent can be configured to start an HTTP listener that can receive custom metrics from external sources, such as scripts, tools, or other applications. The Machine Agent can then report these custom metrics to the AppDynamics Controller, where you can view them in the Metric Browser or use them in health rules, policies, or dashboards. This allows you to monitor any aspect of your system that is not covered by the default Machine Agent metrics34.

The other statements are false because:

B) The Machine Agent cannot send SNMP alerts. The Machine Agent can only receive SNMP traps from external sources and report them as events to the AppDynamics Controller. The AppDynamics Controller can send SNMP alerts to external systems based on health rule violations or events, but this is not a function of the Machine Agent5.

C) The Machine Agent cannot communicate with multiple AppDynamics Controllers. The Machine Agent can only communicate with one Controller at a time, which is specified in the controller-info.xml file in the agent configuration directory. If you want to monitor the same host machine with multiple Controllers, you need to install multiple Machine Agents on the same machine, each with a different Controller configuration and port number.

D) The Machine Agent cannot restart itself if it goes down. The Machine Agent does not have a built-in mechanism to automatically restart itself in case of a failure or a crash. You need to use an external tool or script to monitor the Machine Agent process and restart it if necessary. Alternatively, you can use the AppDynamics Agent Installer to deploy the Machine Agent as a service, which can be configured to restart automatically on failure.

Question #7

Which two statements are true when updating the Database Agent? (Choose two.)

A . The Database Agent must be stopped and restarted during the upgrade.
B . If the agent is moved to a new location during the upgrade, the AppDynamics Controller must be reconfigured to reference the new location of the agent.
C . All data collectors created from the previous agent must be migrated to the new agent.
D . Controller-info.xml is the only file that needs to be migrated from the previous agent to the new agent.
E . After the Database Agent is upgraded, the AppDynamics Controller must be restarted.

Reveal Solution Hide Solution

Correct Answer: AD
AD

Explanation:

According to the Cisco AppDynamics Professional Implementer (CAPI) documents, when updating the Database Agent, you need to follow these steps12:

Stop the agent as described for your specific installation in Start and Stop the Database Agent.

Make a copy of the existing agent directory, <db_agent_home>. Backing up allows you to revert to the previous agent installation if you need to. You can also copy over the controller-info.xml configuration file to the new installation to ensure the agent configuration is maintained.

Install the Database Agent as described for your specific installation in Administer the Database Agent.

Copy the <backup_db_agent_home>confcontroller-info.xml file to the new installation directory, <db_agent_home>conf. To ensure the agent configuration is maintained, copy the <backup_db_agent_home>confcontroller-info.xml file to the new installation directory, <db_agent_home>conf.

Start the new agent. See Start and Stop the Database Agent.

Verify the Database Agent Installation. See Verify the Database Agent Installation.

Therefore, the correct statements are:

The Database Agent must be stopped and restarted during the upgrade. (A) Controller-info.xml is the only file that needs to be migrated from the previous agent to the new agent. (D)

The incorrect statements are:

If the agent is moved to a new location during the upgrade, the AppDynamics Controller must be reconfigured to reference the new location of the agent. (B) This is not true because the controller-info.xml file contains the information about the Controller host, port, account name, access key, and SSL settings. As long as this file is copied to the new agent location, the Controller does not need to be reconfigured.

All data collectors created from the previous agent must be migrated to the new agent. © This is not true because the data collectors are configured on the Controller UI, not on the agent. The agent collects the metrics from the databases and sends them to the Controller. The data collectors do not need to be migrated to the new agent.

After the Database Agent is upgraded, the AppDynamics Controller must be restarted. (E) This is not true because the Controller does not depend on the agent version. The agent and the Controller are compatible as long as they meet the Agent and Controller Compatibility requirements.

Question #10

The application server was restarted after an upgrade.

What are two valid ways to confirm that the upgraded Java Agent is running successfully? (Choose two.)

A . Verify that the application log contains a message indicating success.
B . Verify that the node within the Controller Ul indicates the app agent is reporting.
C . Verify the Java Agent Version metric for that node in the Metric Browser.
D . Verify that the Java Agent log contains a message indicating the agent started successfully.

Reveal Solution Hide Solution

Correct Answer: BC
BC

Explanation:

According to the Cisco AppDynamics Professional Implementer (CAPI) documents, the two valid ways to confirm that the upgraded Java Agent is running successfully are:

Verify that the node within the Controller UI indicates the app agent is reporting. (B) This is a valid way because the Controller UI is a web-based application that allows users to monitor and manage the performance of the applications, tiers, nodes, and other entities that are instrumented by the AppDynamics agents. The Controller UI displays the status of the nodes within each tier, and indicates whether the app agent is reporting or not. If the app agent is reporting, the node icon is green and shows the agent version. If the app agent is not reporting, the node icon is gray and shows the last time the agent reported. The user can also hover over the node icon to see more details, such as the agent type, the agent version, the agent runtime directory, and the agent properties file. The user can verify that the upgraded Java Agent is running successfully by checking that the node icon is green and shows the latest agent version12.

Verify the Java Agent Version metric for that node in the Metric Browser. © This is a valid way because the Metric Browser is a feature of the Controller UI that allows users to view and analyze the metrics collected by the AppDynamics agents. The Metric Browser displays the metrics in a hierarchical tree structure, where each node represents a metric category, a metric name, or a metric value. The user can expand or collapse the nodes, and select or deselect the metrics to view them in a chart. The user can also apply filters, time ranges, baselines, and other options to customize the chart. The user can verify that the upgraded Java Agent is running successfully by navigating to the Java Agent Version metric for that node in the Metric Browser. The Java Agent Version metric shows the version number of the Java Agent that is running on the node. The user can compare the metric value with the expected agent version, and check that the metric is updated after the upgrade34.

The incorrect options are:

Verify that the application log contains a message indicating success. (A) This is not a valid way because the application log does not contain any message indicating the success of the Java Agent upgrade. The application log is a file that records the events and messages that occur in the application server, such as the startup, shutdown, errors, warnings, and debug information. The application log does not record the events and messages that occur in the Java Agent, such as the installation, upgrade, configuration, or reporting. The Java Agent has its own log file, which is located in the <agent_home>/logs directory, and which contains the messages indicating the success or failure of the Java Agent upgrade.

Verify that the Java Agent log contains a message indicating the agent started successfully. (D) This is not a valid way because the Java Agent log does not contain any message indicating the agent started successfully after the upgrade. The Java Agent log is a file that records the events and messages that occur in the Java Agent, such as the installation, upgrade, configuration, or reporting. The Java Agent log contains a message indicating the agent started successfully when the application server is started, not when the Java Agent is upgraded. The Java Agent log does not contain any message indicating the success or failure of the Java Agent upgrade. The Java Agent log is located in the <agent_home>/logs directory, and the message indicating the agent started successfully is “Agent Startup Complete”.
