• 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

3. Who
is
this
guy?

5. My
Fancy
New
Web
ApplicaCon

6. 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?

Fancy
New
Web
ApplicaCon

8. 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?

13. There
has
got
to
be
a
beXer
way!
• Spring
Insight!

14. BETTER
WAY

26. Google
Speed

27. Web
ApplicaCon
Spring

Client
(Browser,
JMeter,
etc.)
Web
Layer
Service

DB
Spring
Insight
Messaging
Caching

28. 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

encoding="UTF-­‐8"?>
<aspectj>
<aspects>
<concrete-­‐aspect
name="foo.bar.BazAspect”

code
required!
