Does anyone know how to get around the issue in Apache JMeter 5.5, 5.6.2 where the Transaction Controller does not Generate the Parent Sample while in CLI Mode. Note: it seems to work ok in GUI Mode but not CLI.
Hi there magic358
Do I understand you correctly that you don’t care about having the the child samples output in the log file as long as you end up with a CSV log file where the “parent sample” added up all the statistics (elapsed time, etc.) correctly?
I haven’t noticed any change from earlier versions, but I see someone with your username posted an issue with no response so far in Generate Parent Sample not working in version 5.6.2 while in CLI Mode · Issue #6056 · apache/jmeter · GitHub.
How does adding -Jjmeter.save.saveservice.subresults=false to the run command work out for you? E.g. apache-jmeter\bin\jmeter -n -t Demo-TransactionController.jmx -l logfile.csv -Jjmeter.save.saveservice.subresults=false.
This approach is coming from someone else’s reply to what I’m guessing is a similiar question in issue 5941, but I’m not sure I understand what the original poster is asking. (jmeter#Transaction Controller勾选generate parent sample，命令行运行没有生效，5.1或5.5版本使用 · Issue #5941 · apache/jmeter · GitHub).
Hi there and welcome to MoT! 
I’ve had this issue also and there is no solution yet. I think you’ve already found this issue since you’ve posted on it:
It’s been broken since 2019:
