  5. 5. How Diagnostic Tools Work?<br />
  6. 6. Server-side Diagnostics: Plug-in Tools<br />An extension to performance testing tools<br />Diagnostic data integrates with test results<br />Break down of transaction response time<br />Diagnostic configuration a part of performance testing tool<br />Easy analysis<br />Some popular tools available- Dynatrace, Deep Diagnostics<br />Recorded version available at <br /><br />
  7. 7. Server-side Diagnostics: Custom Tools<br />Not integrated with any performance testing tool<br />Runs in addition to the performance tests<br />Independent configuration and analysis<br />Existing tools, scripts can be used<br />Support for specific technology, requirements<br />Some popular tools available- Glassbox, InfraRed<br />Recorded version available at <br /><br />
  8. 8. Server-side Diagnostics: Approach<br />Select appropriate diagnostic tool<br />Objective<br />Technology<br />Cost<br />Calibrate overhead of diagnostic tool<br />Apply method filters<br />Bottleneck identification<br />Top ‘X’ methods and queries<br />Response time distribution across layers<br />Recorded version available at <br /><br />
  9. 9. Client-side Diagnostics<br />Vastly impacts end user experience<br />Categories of client side<br />Mobile diagnostics<br />Measuring app performance on mobile device<br />Limited hardware resources<br />Browser diagnostics<br />Identifies browser bottlenecks in page loading<br />Recorded version available at <br /><br />
  10. 10. Client-side Diagnostics: Approach<br />Mobile diagnostics approach<br />Existing tools (J2ME profiler, Android Trace)<br />Custom solution<br />Use of Aspect oriented frameworks (AspectME, AspectLUA)<br />Use byte code instrumentation<br />Re-usable aspects<br />Configure aspect within application binaries<br />Browser diagnostics approach<br />Diagnostics plugins - Firebug, SpeedTrace, HttpWatch<br />Analyze statistics<br />Identify bottlenecks - Java script execution, memory leaks, page loading<br />Recorded version available at <br /><br />
  11. 11. Benefits of Diagnostic Tools<br />Drill down user transactions to methods, DB queries and web service calls<br />Performance visibility across complete application<br />Identifies and isolates performance bottlenecks<br />Costly queries, high method invocations, method execution time, suspicious memory consumption<br />Enhanced collaboration<br />Rich analysis dashboard<br />Built-in heuristics<br />Integrates with IDE<br />Reduces time and efforts involved in bottleneck identification<br />
  12. 12. Case Study: Plug-in Diagnostic Tools<br />The Client<br />One of the leading companies in home health care<br />Key Challenge<br />Performance bottleneck identification from performance testing<br />Lack of expertise in diagnostic tools<br />Impetus Solution<br />Proposed SandStorm and its diagnostic plug-in<br />Calibrated diagnostics overhead (~2%-3%)<br />Captures diagnostics data across method & queries during test execution<br />Performed client side diagnostics using Firebug<br />Consolidated data enabled quick isolation of performance bottlenecks<br />Benefits Realised<br /><ul><li>Faster performance bottleneck identification
  13. 13. Streamlined and efficient performance engineering
  14. 14. No performance issues in production</li></li></ul><li>Case Study: Custom Diagnostic Tools<br />The Client<br />Leading provider of financial risk management solutions<br />Key Challenge<br />Mechanism to isolate code bottlenecks during performance testing<br />Performance monitoring of application in staging environment<br />Reusing Load Runner scripts & performance center scenarios<br />Impetus Solution<br />Proposed implementing an extensible, custom diagnostic solution<br />Built diagnostic f/w using Aspect Oriented Programming using AspectWerkz, Jamon, Jarep libraries<br />Deployed and configured utility in a staging environment<br />Reports generated & analysed to identify expensive queries<br />Benefits Realised<br /><ul><li>Monitoring mechanisms in staging environment
