A customer needs to understand how establishing standards for naming Applications. Tiers, and Nodes can help them determine the root of a problem when users are working with AppDynamics or receive an alert Which three statements about establishing naming conventions are true? (Choose three.)

Show Suggested Answer Hide Answer
Suggested Answer: A, B, E

According to the Tiers and Nodes document1, establishing standards for naming applications, tiers, and nodes can help you identify and organize the components of your monitored environment, as well as troubleshoot performance issues and health rule violations. Some of the statements about establishing naming conventions are true:

Application Tier and Node values can be configured in the application agent startup script: This is true for Java agents, as you can pass values to the agent that will be used as the application, tier, and node name for the system.For example, you can use the -Dappdynamics.agent.applicationName, -Dappdynamics.agent.tierName, and -Dappdynamics.agent.nodeName properties to specify the names in the JVM startup script2.

Node names must be unique across the entire business application: This is true, as node names are used to identify the individual instances of the application components that are monitored by AppDynamics. Having duplicate node names can cause confusion and errors in the data collection and reporting.Therefore, you should use a naming convention that ensures uniqueness and clarity for each node1.

Application Tier and Node values can be configured in the controller-info.xml file: This is true for Java agents, as you can also configure the names in the controller-info.xml file, which is located in the /conf directory. The controller-info.xml file contains the properties that define the agent identity and connection to the Controller.You can use the , <tier-name>, and <node-name> elements to specify the names in the file2.

Some of the statements about establishing naming conventions are false:

Nodes that reside on different Tiers and different machines (hosts) can have duplicate Node names: This is false, as node names must be unique across the entire business application, regardless of the tier or the host they belong to. Having duplicate node names can cause confusion and errors in the data collection and reporting.Therefore, you should use a naming convention that ensures uniqueness and clarity for each node1.

Nodes that reside on the same Tier but on different machines (hosts) can have duplicate Node names: This is also false, as node names must be unique across the entire business application, regardless of the tier or the host they belong to. Having duplicate node names can cause confusion and errors in the data collection and reporting.Therefore, you should use a naming convention that ensures uniqueness and clarity for each node1.

Totally. And for options B, C, and D, I think B is true - node names do need to be unique across the entire business application. C and D seem a bit more tricky though.

Hmm, I'm not so sure about C and D. I think the key is that the node names need to be unique within a single tier, even if they're on different machines.

Definitely. I'd say options A and E are definitely true, since we can configure those values in the agent startup script and the controller-info.xml file.

Yeah, that makes sense. And I'm pretty sure B is true too - the node names need to be unique across the entire business application, not just within a single tier.

Okay, let's take a look at the options. I think A and E are both true - you can configure the application tier and node values in both the agent startup script and the controller-info.xml file.

Haha, I wonder if the person who wrote this question has ever actually had to troubleshoot an issue in AppDynamics. They're making it sound like naming conventions are the solution to all your problems.

I agree, this feels more like a trivia question than a meaningful assessment. But I suppose we have to play the game if we want to pass the exam.

I'm not a huge fan of this question. It seems like it's just testing our knowledge of the AppDynamics configuration rather than our actual understanding of the concepts.
