1. Identifying Software Performance Bottlenecks using Diagnostic ToolsbyImpetus Technologies Recorded version available at http://www.impetus.com/webinar_registration?event=archived&eid=46

2. Outline Typical process of bottleneck identification Diagnostic tools How diagnostic tools work? Diagnostic tools usage scenarios Server side diagnostics Client side diagnostics Benefits of diagnostic tools Real world examples Q&A Recorded version available at http://www.impetus.com/webinar_registration?event=archived&eid=46

3. Typical Process of Bottleneck Identification Extensive time, resources, and efforts involved

4. Diagnostic Tools Response time break down Tiers, components and layers Information Bottleneck methods, costliest queries, memory leaks Deployment options Development environment, load testing environment, production Differ from profilers Low overheads, isolates code bottlenecks Recorded version available at http://www.impetus.com/webinar_registration?event=archived&eid=46

5. How Diagnostic Tools Work?

6. Server-side Diagnostics: Plug-in Tools An extension to performance testing tools Diagnostic data integrates with test results Break down of transaction response time Diagnostic configuration a part of performance testing tool Easy analysis Some popular tools available- Dynatrace, Deep Diagnostics Recorded version available at http://www.impetus.com/webinar_registration?event=archived&eid=46

7. Server-side Diagnostics: Custom Tools Not integrated with any performance testing tool Runs in addition to the performance tests Independent configuration and analysis Existing tools, scripts can be used Support for specific technology, requirements Some popular tools available- Glassbox, InfraRed Recorded version available at http://www.impetus.com/webinar_registration?event=archived&eid=46

8. Server-side Diagnostics: Approach Select appropriate diagnostic tool Objective Technology Cost Calibrate overhead of diagnostic tool Apply method filters Bottleneck identification Top ‘X’ methods and queries Response time distribution across layers Recorded version available at http://www.impetus.com/webinar_registration?event=archived&eid=46

9. Client-side Diagnostics Vastly impacts end user experience Categories of client side Mobile diagnostics Measuring app performance on mobile device Limited hardware resources Browser diagnostics Identifies browser bottlenecks in page loading Recorded version available at http://www.impetus.com/webinar_registration?event=archived&eid=46

10. Client-side Diagnostics: Approach Mobile diagnostics approach Existing tools (J2ME profiler, Android Trace) Custom solution Use of Aspect oriented frameworks (AspectME, AspectLUA) Use byte code instrumentation Re-usable aspects Configure aspect within application binaries Browser diagnostics approach Diagnostics plugins - Firebug, SpeedTrace, HttpWatch Analyze statistics Identify bottlenecks - Java script execution, memory leaks, page loading Recorded version available at http://www.impetus.com/webinar_registration?event=archived&eid=46

11. Benefits of Diagnostic Tools Drill down user transactions to methods, DB queries and web service calls Performance visibility across complete application Identifies and isolates performance bottlenecks Costly queries, high method invocations, method execution time, suspicious memory consumption Enhanced collaboration Rich analysis dashboard Built-in heuristics Integrates with IDE Reduces time and efforts involved in bottleneck identification

13. Streamlined and efficient performance engineering

16. Summing Up Diagnostic tools differ from profilers Diagnostic tools can be used in multiple environments Software diagnostics an integral piece of a successful performance engineering strategy Custom diagnostic solutions for specific requirements Calibrate the overhead of diagnostic tool before actual usage Recorded version available at http://www.impetus.com/webinar_registration?event=archived&eid=46
