Question

Refer to the exhibit. A developer using AppDynamics notices a transaction that is normal within the established baseline, but is blocked for a much of its execution time. The developer opens the transaction and sees that HTTP calls and Java methods use most of the transaction time. Which action must the developer take to identify the cause of the issue to troubleshoot?

Why each option

To troubleshoot a blocked transaction that is otherwise normal within its baseline but spends significant time on HTTP calls and Java methods, the developer should investigate the health of the specific node processing the transaction.

AClick the node health link in the dashboard panel.Correct

Since the transaction itself is within its baseline but blocked, indicating a wait state, and consuming time in HTTP calls and Java methods, clicking the node health link in AppDynamics would provide insights into the underlying server or application instance where the transaction is executing, revealing resource constraints, thread contention, or other issues specific to that node. This allows for deeper investigation into the specific server's performance, resource utilization, or process status, which could explain the blocking.
