how can we capture all requests going from JMeter running on Linux?

My test is running on Linux VM via JMeter [command line]. Access logs of apache server shows that few requests didn't reached to it and for few requests, it is giving 400 response [i.e. bad request]

So i wanted to capture all requests going from JMeter and with parameters if possible.

Is there any way of doing it?

  1. You can do it using tcpdump tool like:

    tcpdump -i any -s0 -w /path/to/dump.pcap

    And once JMeter test finishes open dump.pcap file with Wireshark and inspect packets

  2. Alternative option is configure JMeter to save request and response data. It can be done in 2 ways:

    • Add the following lines to user.properties file (lives in "bin" folder of your JMeter installation)

      jmeter.save.saveservice.output_format=xml
jmeter.save.saveservice.response_data=true
jmeter.save.saveservice.samplerData=true
jmeter.save.saveservice.requestHeaders=true
jmeter.save.saveservice.url=true
jmeter.save.saveservice.responseHeaders=true

    • pass above properties via -J command-line argument like:

      ./jmeter -Jjmeter.save.saveservice.output_format=xml -Jjmeter.save.saveservice.response_data=true -Jjmeter.save.saveservice.samplerData=true -Jjmeter.save.saveservice.requestHeaders=true -Jjmeter.save.saveservice.url=true -Jjmeter.save.saveservice.responseHeaders=true -n -t example.jmx -l example.jtl

    Once test finishes open resulting example.jtl file in JMeter GUI with View Results Tree listener - you will be able to see request and response details along with parameters, variables, etc.
