The Performance Analyst should open the Business Transactions view and enable Show Trends. This presents historical behavior for individual Business Transactions, making it possible to identify which transactions experienced a decline in calls per minute and when the change began. The analyst can compare workload patterns across transactions and correlate the decrease with changes in response time, errors, transaction activity, or application usage.

The Top Business Transactions by Load widget emphasizes the highest-volume transactions for the selected period, but it may not clearly expose transactions whose volume has sharply declined. Plotting application-level Calls/min in the Metric Browser confirms that total workload decreased but does not immediately identify the affected Business Transactions. The Application Flow Map focuses on tier and dependency relationships, while Transaction Score summarizes transaction performance classifications rather than workload trends.

The Show Trends capability is therefore the most direct method for examining historical transaction behavior and isolating the Business Transactions responsible for the workload change.

Relevant CAAPA Study Guide topics include Business Transaction Monitoring, Show Trends, Calls per Minute, Workload Analysis, Historical Comparison, and Application Performance Troubleshooting.

A transaction snapshot in AppDynamics is a detailed report of a single execution of a business transaction. Its primary purpose is to analyze issues with a specific business transaction by providing a comprehensive view of the transaction ' s execution path, including timing, call graphs, and database queries. This allows performance analysts and developers to drill down into individual transactions to diagnose performance bottlenecks, errors, or anomalies.

To share snapshot details from the snapshot window in AppDynamics, the options to " Download PDF " and " Export " are typically used. " Download PDF " allows users to generate a PDF report of the snapshot details, providing a convenient and portable format for sharing and review. The " Export " option enables the extraction of snapshot data in various formats (e.g., CSV, XML), facilitating further analysis or sharing with other tools and stakeholders.

To monitor end-to-end latency performance metrics, a Performance Analyst must first define the end-to-end latency transaction. This involves configuring the business transactions to include the necessary entry and exit points that capture the complete flow of the transaction, thereby enabling the measurement of the total latency.
