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.
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.
