500-420 Exam Dumps : Cisco AppDynamics Associate Performance Analyst (CAAPA)

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.

Relevant CAAPA Study Guide topics include Browser Real User Monitoring, Browser Applications, End-User Response Time, Page and AJAX Performance, User Experience Analysis, and Client-Side Performance Trends.

The Live Preview option allows a Performance Analyst to stream entry points detected in the application while a Business Transaction Discovery Session is active. As representative traffic executes, the Application Agent reports candidate entry points in near real time, helping the analyst identify application activity that automatic Business Transaction detection may not already recognize.

This capability is especially useful for proprietary frameworks, background processes, scheduled jobs, and other nonstandard execution paths. The analyst can observe the entry-point activity, determine which class and method represent the start of a meaningful transaction, and then use that information to configure an appropriate Custom Match Rule.

Live Preview does not provide streaming application or agent logs. Searching and browsing classes and methods is a related Discovery Session capability, but it is distinct from the Live Preview function. Likewise, rule validation can be performed after defining detection criteria, but the primary purpose of Live Preview is to expose active entry points as they occur.

Relevant CAAPA Study Guide topics include Business Transaction Discovery Sessions, Live Preview, Entry-Point Detection, Class and Method Browsing, Custom Match Rules, and Nonstandard Framework Instrumentation.

The Transaction Score view in the Application Dashboard categorizes transactions by load, response time, errors, slow transactions, and stalled transactions. It provides an aggregated value for a specific time range, giving an at-a-glance indication of the health and performance of business transactions.
