Can we parameterize Thread schedule details like Start Thread count, Initial delay etc. in Ultimate thread Group using csv/txt files?

Question

We are trying to parameterize Thread schedule details like Start Thread count, Initial delay etc. Since we have 50+ thread groups and handling them has become an issue.

Would like to know if Jmeter has any unknown feature for this or a workaround to achieve this? Can we parameterize these values from a csv/txt file?\

Note: We have 50+ thread groups, hence using ${__CSVRead} and retrieve different values didn't work out.

Have tried out ${__CSVRead} but since we need different values for each thread, this isn't working out.

I can only think of "known" feature - using either user.properties file or a custom .properties file, i.e.

thread.group.1.start.threads=10
thread.group.1.initial.delay=5
thread.group.2.start.threads=50
thread.group.1.initial.delay=20
etc.

and you will be able to use __P() function in the Ultimate Thread Group to read the values from the .properties file:

If you put the values into user.properties file - you won't need to do anything else, the file will be picked up automatically, if you decide going for the custom .properties file - you will need to pass it via -q command-line argument:

 jmeter -q /path/to/your/thread/group.properties -n t .....
