It would be nice if I could add to the output of a Summary Report or log the current value of a parameter as a column. When driving JMeter from some external app it would be very good to see the values of the parameter it was called with in the logfile - withouth that it is difficult to separate them. On the GUI: I did some loadtesting and currently the only way I could comfortably do that was to create several thread groups with different number of users and the same rampup time, specify that one threadgroup must finish before the other starts and put a Summary Report page in each threadgroup. I than copy/pasted the results from each threadgroup to a table and made a chart from that. This would have been much easier if I could just place a Summary Report on the test level. The problem is that now it would summarise results from all threadgroups. I could of course add the name of the thread group to all labels under that group, but that would be too much work. Instead how nice it would be if I could just say to output the threadgroup name as well and so generate a separate summary on that page.
The code in SVN has been updated to allow a list of variables to be specified; the variables and their values are saved in JTL files. See the "sample_variables" entry in jmeter.properties As to adding the thread group name to the Summary (and Aggregate?) reports, this sounds like a good idea.
Group name box added to Aggregate and Summary reports. SVN r642732
