Question 2

Which two would be marked as an exception in AppDynamics? (Choose two)



Answer : B, C

An exception in AppDynamics is a code-level event that indicates a problem or abnormality in the execution of a business transaction. AppDynamics captures and presents information on exceptions in the monitored environment, and allows you to configure the rules and criteria for detecting and reporting exceptions.

According to theErrors and Exceptions - AppDynamics, the following two types of events would be marked as an exception in AppDynamics:

A custom-configured error method and error message: This is a type of event that you can define as an exception based on a specific method and message that indicate an error condition in your application code. You can configure the error detection rules to mark a business transaction as an error and capture the exception information when such a method and message are encountered. For example, you can configure a rule to mark a business transaction as an error and capture the exception when the methodcom.example.MyClass.myMethodreturns the messageInvalid input.

Any message that is logged with a severity of Error or Fatal: This is a type of event that AppDynamics automatically detects as an exception based on the log messages that are generated by your application code. AppDynamics scans the log messages for the keywordsErrororFatal, and marks the business transaction as an error and captures the exception information when such a message is found. For example, AppDynamics will mark a business transaction as an error and capture the exception when the log message containsError: Null pointer exception.

Therefore,B(a custom-configured error method and error message) andC(any message that is logged with a severity of Error or Fatal) are two types of events that would be marked as an exception in AppDynamics.Reference:

Question 5

Java APM agents used in a production environment are consistently found to be disabled while no development environments exhibit this behavior Given that agents in both environments use the default configuration, what solution should be implemented to resolve this issue?



Answer : D

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.

Question 6

Which three types of performance degradation analysis are used with Business Transaction metrics? (Choose three.)



Answer : A, B, E

Business Transaction metrics are the key performance indicators that measure the health and performance of your applications. They include metrics such as average response time, calls per minute, errors per minute, and so on. You can use various types of performance degradation analysis to identify and troubleshoot the root causes of performance issues using Business Transaction metrics.

According to theTroubleshoot Business Transactions - AppDynamics, the following types of performance degradation analysis are used with Business Transaction metrics:

Correlation Analysis: This type of analysis helps you to find the correlation between different metrics and events that may affect the performance of your Business Transactions. For example, you can use the correlation analysis to see how the response time of a Business Transaction is related to the CPU utilization of a node, or how the error rate of a Business Transaction is related to the number of slow database calls.

Remote Services Analysis: This type of analysis helps you to understand how the performance of your Business Transactions is impacted by the calls to remote services, such as databases, web services, message queues, and so on. For example, you can use the remote services analysis to see the response time, call count, error count, and wait time of each remote service call, and drill down to the details of each call.

Compare Releases: This type of analysis helps you to compare the performance of your Business Transactions across different releases of your application. For example, you can use the compare releases analysis to see how the response time, error rate, and throughput of your Business Transactions have changed after a new deployment, and identify any performance regressions or improvements.

Therefore,A(Correlation Analysis),B(Remote Services Analysis), andE(Compare Releases) are three types of performance degradation analysis that are used with Business Transaction metrics.Reference:
