A framework for empirical evaluation of Java application performance

Master’s thesis

Author: Viktor Reinok
Supervisor: Juhan Peep Ernits

What is this repository for?

FFEOJAP is a tool integrable into CI loop to detect and track performance issues. The framework will provide solution for following questions:

1. How do I find performance issues?
2. How do I narrow down the root cause of the performance issue?
3. How do I validate the effectiveness of the fix
4. How do I make sure the fix does not affect other parts of the system in negative way.

Version 0.0.1

How do I get set up?

Following dependencies are required:

• JDK 7
• Maven 3
• Elasticsearch (Running locally. Accessible on port 9200) ES 2.3 download

Run an example application Petclinic

#!command line (windows)
git clone https://bitbucket.org/viktor_reinok/petclinic.git
cd petclinic
mvn clean tomcat7:run 

Launch the load generator

#!command line (windows)
# new shell session
git clone https://bitbucket.org/viktor_reinok_thesis_team/thesis.git
cd thesis

mvn -pl load-generator -am package assembly:single -DskipTests -P load-generator-build-profile
cd load-generator/target
java -jar load-generator-jar-with-dependencies.jar 0000

Launch the data analyzer

#!command line (windows)
cd../..
mvn -pl analyzer -am package assembly:single -DskipTests -P data-analyzer-build-profile
cd analyzer/target
java -jar analyzer-jar-with-dependencies.jar
 

Emulate the source code change and re launch the Petclinic applicatoin

#!command line (windows)
# stop existing deployed instance of Petclinic
git checkout abc4b24337c8fce97aa557620b8ad8d7e047a49a -f
mvn clean tomcat7:run

Launch the load generator again

#!command line (windows)
# back in thesis shell
cd../..
mvn -pl load-generator -am package assembly:single -DskipTests -P load-generator-build-profile
cd load-generator/target
java -jar load-generator-jar-with-dependencies.jar 0001

Launch the data analyzer again

#!command line (windows)
cd../..
mvn -pl analyzer -am package assembly:single -DskipTests -P data-analyzer-build-profile
cd analyzer/target
java -jar analyzer-jar-with-dependencies.jar
