Why request in View results in a tree listener shows “No data to display” in non-gui mode

Question

Expected Requests and Response are showing after executing jmeter script in GUI mode but when the same is execcuted in non-gui mode, for few requests it shows "No data to display" and Response is empty.

This was encountered in jmeter v4. Can anybody help as in why such variance in requests when script is executed in non-gui mode?

This is done intentionally, JMeter removes request and especially response data from sample results (mainly because it cannot be stored in CSV format) in order to reduce memory consumption and disk IO required to aggregate and store the data.

If you really need to see request and response data you can "tell" JMeter to store it by adding the next 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

JMeter restart will be required to pick the properties up. Once done - re-run the test and make sure to use the different output .jtl file (or delete the existing one) - this time it will have much more results suitable for displaying in the View Results Tree listener
