JMeter Plugin

Compatibility with Sonar

Description / Features

This plugin collects performance tests results from Apache JMeter. Apache JMeter may be used to test performance both on static and dynamic resources (files, Servlets, Perl scripts, Java Objects, Data Bases and Queries, FTP Servers and more). It can be used to simulate a heavy load on a server, network or object to test its strength or to analyze overall performance under different load types. You can use it to test your server/script/object behavior under heavy concurrent load.

If it is the first time you hear from Apache JMeter then you should try it before using this plugin.

The following metrics are included in Sonar:

• Duration (in seconds)
• Error density (number of errors / number of requests * 100)
• Average response time for requests
• Average response time for transactions
• Successful requests per minute
• Successful requests per minute and user
• Response time deviation for requests
• Response time deviation for transactions
• Number of requests
• Number of transactions
• Successful transactions per minute
• Successful transactions per minute and user

This is an example of the widget you will see in Sonar:

Usage & Installation

JMeter

JMeter installation is very easy. JMeter is developed with Java and it is distributed as a compressed file.

You can download it from http://jakarta.apache.org/jmeter and then run the provided script (bin/jmeter).

Recording a test in JMeter

You can find a step by step tutorial in JMeter's website: http://jakarta.apache.org/jmeter/usermanual/jmeter_proxy_step_by_step.pdf

It describes how to record a test plan using the JMeter proxy.

SONAR JMeter plugin uses the results datafile generated by JMeter (file with extension .JTL) so remember to configure your test plan to store the results in a single JTL file.

JMeter Report Server

JMeter Report Server is a server that generates performance reports from JMeter results. SONAR JMeter Plugin uses this server to get the performance metrics from the projects.

It must be installed on the same machine with JMeter tool. The server will read the JTL files to get all the data.

JMeter Report Server Configuration

JMeter Report Server needs to know where the JTL files are located. You can set this location in the properties file bundled with the server (properties/jmeter-report-server.properties).

For example:

Note that you have to specify a "name" for the testconfig jtl path. In the example we have used "iceweb".

Known limitations
