Agenda •  What Just Happened?

– Agile Development, QA, Stress & Performance tesCng –  Logging? – Debugger?

•  STS & Integrated in Tomcat (tc Server) •  Spring Insight Demo Time •  JMeter & Google Chrome Speed Tracer •  How it works •  Plugins & AnnotaCons •  Wrap up

My Fancy New Web ApplicaCon

ApplicaCon Development & TesCng

•  So your building your fancy new web applicaCon –  Is it working the way you expected? – What caused that failure? – How is the performance? – Why is it slow? – What the heck is Hibernate (or whatever) doing?

My Fancy New Web ApplicaCon

What do you do when it fails?

•  Check the logs? – Timestamps – Session IDs, User IDs – Log all the parameters – UGH?

•  Run the debugger? – Typically doesn’t help with performance

•  And what do you do in QA and Performance TesCng? When it fails? When it is slow?

There has got to be a beXer way!

•  Spring Insight!

How does it work?

•  Spring Insight uses automaCc code instrumentaCon to monitor your applicaCon

•  It does this by introspecCng exisCng annotaCons and interfaces for key aspects of your applicaCon

•  It then uses AspectJ AOP point cuts to monitor the code

•  Runs in tc Server (Tomcat) beside your web applicaCon

AnnotaCons

•  If you want to monitor more aspects of your code you can simply annotate the methods

Dynamic Concrete Aspects <?xml version="1.0" encoding="UTF-‐8"?> <aspectj> <aspects> <concrete-‐aspect name="foo.bar.BazAspect” extends="com.springsource.insight.collecCon.method.custom.CustomConcreCzedOperaConCollecConAspect"> <pointcut name="collecConPoint"

expression="execu;on(* foo.bar.Baz.mySuperDuperMethod(..))" /> </concrete-‐aspect> </aspects> </aspectj>

Dynamic Concrete Aspects

•  Instrument classes and methods that are not covered by plugins or Insight annotaCons

•  Defined in AspectJ XML configuraCon •  No changes to source code required!

Spring Insight •  AutomaCc •  No Coding & No ConfiguraCon

•  Shows Errors •  Shows Performance •  Pluggable •  Answers: “What Just Happened?”

Wrap Up

•  Helps developers, QA Testers, and in Stress and Performance tesCng to answer: “What Just Happened?”
