About JChav

JChav is a way to see the change in performance of your web application over time, by running a benchmark test for each build you produce.

Example of the JChav reports output.

How does it work?

  • You build and deploy your application.
  • You write a JMeter test plan to exercise your application.
  • From Ant, you run the JMeter test plan and log the results, using the Ant JMeter task.
  • JChav reads all the JMeter logs from each of your runs (one per build), and produces a set of charts for each test in each run.
  • Each time you deploy, re-run the JMeter tests and the JChav tool to update the charts to show the change in performance.
By running this often you can see the effect of code change on your application performance.

Getting started

JChav is made available under the Apache 2.0 license.

Live Demo

If you would like to see what the reports look like we have a live demo of the site available here. It shows a series of threads accessing the www.digg.com site. The example section below shows the scripts used to produce these results.
