The Transaction Controller does not calculate throughput, it merely
aggregates samples.
What Listener are you using?
The ones that do aggregation generally ignore the thread name, and
just aggregate based on the sampler name, so throughput should be for
all threads.

To complete that Deepak Shetty said, you can add also a Simple Data Writer
at the transaction level to log in a file.

I.e. your requests are children of the transaction controller . Then add the

all the indvidual requests) Does this work for you?

RE: Using transaction controller to count all iterations of each
thread
Posted by Petteri Lyytinen <Pe...@uoma.fi>.
Thank you Deepak, that actually solved the problem I had.
The mistake that I had made was that the Transaction Controller was on the same level with the HTTP Request samplers, instead of the samplers being children of the controller. I removed the Recording Controller and placed the HTTP Request samplers under the Transaction Controller and now it's working the way I was originally hoping it would.
Thank you so much!

RE: Using transaction controller to count all iterations of each
thread
Posted by Petteri Lyytinen <Pe...@uoma.fi>.
I'm apparently not explaining myself very clearly.
I have a thread group with a total of 31 HTTP Request samplers under a Recording Controller. I'm not interested in how many singular HTTP Requests the system is able to process per time unit (second/minute/hour), but it would be relevant to see how many times per time unit the system is able to process the full 31 HTTP Request flow.
Now, if I add a Transaction Controller under the Thread Group, it will show me how many full flows the system can process per time unit, but this is only true when the number of loops is exactly one. If the number of loops is increased to two or more, the Transaction Controller becomes useless as it only shows the processing capabilities from the first loop (per thread) and doesn't update after that - regardless of the number of loops defined in the Thread Group.
So, if I've set JMeter to use 15 concurrent threads, with each thread looping 10 times, I would like to be able to see how many full 31 HTTP Request flows, on average, the system is able to process per time unit, for all 150 iterations completed. Again, the system's processing capabilities per call are irrelevant, only the full flow matters.
So, the question remains: Is there any way to achieve that in JMeter?
I'm sure I won't be able to make it any more clear than that. :)

That's what JMeter does normally.

Don't use an aggregate Listener, use View Results in Table.

Okay, let's rephrase the question once more. Nevermind the transaction controller mentioned in the subject.
What I want: With 15 threads doing 10 iterations each I want to see 150 results.
What I don't want: With 15 threads doing 10 iterations each I don't want to see only 15 results.
So the question is: Is there any way I could possibly see the time it takes for each thread to complete each iteration, not just one result per thread?

Both of these use a lot of memory (Aggregate will be better in the
next version of JMeter), so should be disabled for long runs.
Summary Report is cheaper; please read:

The TC does not calculate any statistics nor does it loop.
http://jakarta.apache.org/jmeter/usermanual/component_reference.html#Transaction_Controller
Use the TC controller to enclose the samples you want to aggregate,
and then use the appropriate Listener to summarise these.

So is there a way to get the Transaction Controller to show the time
it takes for each loop to complete (or how many loops are completed
per second/minute/hour), when doing several loops per thread, with
multiple concurrent threads?
