Executing Jmeter testplan using Java

We all know pretty well that JMeter is a server performance testing tool for both static and dynamic resources. I've had successfully used JMeter for the above written purpose through it's easy to use GUI interface. Recently we've been experiencing a lot of "server down" issue but we're unable to find out when exactly server is down until we're requesting something to it and get nothing in return.

So I thought of using JMeter as a solution here. Using JMeter I would be hitting the server at particular intervals, say once in every 3hours and get a response back which will correctly identify that server is working fine. Using it in GUI mode is not apt. It needs to be scheduled for every 3 hours.

Through a bit of Google's help I learnt JMeter could also be used in "non GUI mode". So I took the script and made a bat file of it. I then triggered the bat file using Java cod with the help of Timer class for scheduling. The script inside the bat file is :

jmeter -n -t E:\Jmeter.jmx -l E:\test.txt

Using above script I get summary report in test.txt which looks like:

1440049645804,576,SOAP/XML-RPC Request,200,OK,Thread Group 1-1,text,true,583,1,1,574

The result was same even when the server was down. I added "View Results Tree" as listener in GUI and saved it but still the result was same. By default the non GUI mode gets just the summary. I would want the Response data of Result tree as well.

enter image description here

The Response data shown above confirms whether server is returning valid data or not. Is there any way I could add up the Response data to my result file?

Also I found the test plans could be run inside the java code using the JMeter API's and Interface i.e JavaSamplerClient . I searched but could not find a live example that I could understand clearly.

Thanks in advance.

  1. In order to see response data you need to do the following:

    • Switch JMeter output format to XML
    • "Tell" it to save response data

    Command line solution will look like:

    jmeter -Jjmeter.save.saveservice.output_format=xml -Jjmeter.save.saveservice.response_data=true -n -t E:\Jmeter.jmx -l E:\test.txt

  2. In regards to running JMeter test from Java see chapter 4.2 Running an existing JMeter Test from Java code of the 5 Ways To Launch a JMeter Test without Using the JMeter GUI guide.

  3. JavaSamplerClient - is the way of creating custom Java Request Samplers, I doubt that it is what you looking for
