The problem we have is that report requires tc to not generate a parent sample otherwise we loose important information: - error codes of underlying requests - number of request to compute hits - precise response time for each request But if we don't generate parent sample: - errors can count twice(for the child request and its parent TC) - percentiles are also impacted as you describe it TC are in fact a pain in the ass in Jmeter code. But they are still useful to group requests. > example 2: > TC1: > request 1 > request 2 > request 3 > request 4 > > Here what I want to see is a Graph that contains min, max, percentil... for > TC1 + request 3 + request 4 So you would check generate parent sample here ? > > > Antonio > > > > Thank you > > > > -- > > Regards. > > Philippe M. > > > -- Cordialement.
