Issue related to the Virtual User count in the overview of a test run page

[anita-achari]

Hi,
After running a test with 20 users (Number of threads) using JMeter and uploading the JTL report to JTL- reporter, overview of the test run shows the number of virtual users as 1. I have attached the screenshot here.

Hi @anita-achari - Do you use multiple machines to generate the load (distributed testing https://jmeter.apache.org/usermanual/jmeter_distributed_testing_step_by_step.html) ?

[anita-achari]

No. We are not using multiple machines.

[ludeknovy]

Ok. Could you please provide an anonymized sample of the data?

The provided CSV sample contains only all_threads = 1, so if your full file looks like this, indeed, the virtual users will be 1.

I've edited your sample, and set a couple of last lines all_threads = 2. And the virtual users changed to 2, so it seems to be working correctly.
