The Top Business Transactions – by Errors dashboard is specifically designed to rank Business Transactions according to their error activity. When the application’s aggregate Error Count increases, this view quickly identifies which transactions are generating the largest number or proportion of errors during the selected time range. The Performance Analyst can then select a high-error Business Transaction and drill down into its transaction snapshots, exceptions, affected tiers, and backend dependencies.

Transaction Score – Snapshots categorizes transactions by performance condition, such as normal, slow, very slow, stalled, or error, but it is not the most direct ranked view for determining which Business Transactions are driving an overall increase in errors. Transaction Snapshots – All Snapshots provides execution-level diagnostic records and requires more manual filtering. Application Flow – Grid View is primarily used to compare tiers, nodes, and backend dependencies rather than rank Business Transactions by error contribution.

In environments where virtual machines are frequently created and destroyed, using the agent configuration properties -Dappdynamics.agent.reuse.nodeName and -Dappdynamics.agent.reuse.nodeName.prefix can be beneficial. These settings allow AppDynamics agents to reuse node names for newly created instances, facilitating consistent monitoring and tracking across dynamic environments. This approach helps maintain clarity in application topology and ensures that performance data remains coherent even as the underlying infrastructure changes.

The Performance Analyst should use Browser Apps. This area contains Browser Real User Monitoring data and presents application performance from the actual end user’s perspective. It provides detailed trend graphs for browser pages and AJAX requests, including metrics such as end-user response time, page load time, network time, server time, DOM processing time, resource-loading time, request volume, errors, and geographic or browser-related performance variations.

These measurements enable the analyst to determine whether a performance problem originates in the browser, network, content-delivery path, application server, or a downstream dependency. The graphs can also be filtered by time range, page, browser type, device, operating system, location, and other user-session dimensions.

Transaction Analytics is used for querying and analyzing transaction and business-event data. Remote Services focuses on backend dependencies and external service calls. Applications primarily provides server-side APM visibility into Business Transactions, tiers, nodes, and application flow.
