I am using Transaction controller for my testing process, and I have 5 transaction controllers. Now I want to specify think time (Timer) between each Transaction controller say 300 ms.
When I add constant timer, then every sampler takes 300ms think time to process and because of this the overall response is increased a bit.
Is there any other way to give think time to only transaction controller and not individually sampler?
You can work it around as follows:
Add a Beanshell Post Processor as a child of the last request in each Transaction Controller
Put the following code into the Post Processor's "Script" area:
Thread.sleep(300L);
Configure Transaction Controller to
generate parent sample
not to include duration of post processors and timers into the generated sample
See Using JMeter's Transaction Controller guide for more detailed explanation.
I could think of 2 options that would provide required solution:
1)The easiest way would be to put the timer to the first request of the following transaction controller.
OR
2) At the end of the Controller add Test Action which can be found under Sampler where you can provide PAUSE time in milliseconds.
Hope this helps.
Add a Test Action and select pause. Set this to 0ms and then add a Gaussian Random timer to the test action. Configuring timers this way will allow you to run the test with pauses or without (for debugging), test actions configured as timers will not be skipped when clicking "Start No Pauses", while the Gaussian timers attached to test actions will.
The best way to do this is via "Add think times to children" on the Recording controller. This will insert a "think time" action between each controller. Then you specify the duration in ms in each Think Time action.
Usually, I would use ${thinkTime} as the duration, then specify thinkTime = 10000 or similar in the "User defined variables" config element you can add to the top of your project.
The think time is between transaction controllers, not between requests in a controller.
I am using jmeter 5.3.

I am using jmeter to load test my application.I have a sampler under Transaction Controller.But we have updated some of the parameters in the request.So i want to run 90% time old sampler and 10% of time new sampler,which are almost doing same thing but only have some extra parameters in second sampler.I tried checking switch controller but could not figure out if it will work for my requirements.My test plan looks similar to this
If you want to continue with the Switch Controller you can proceed with the following "Switch Value" (or equivalent)
${__javaScript( var s="000000000001"; s.charAt( Math.floor(Math.random()*s.length) ))}
Another options are in (you may find them easier to implement):
Throughput Controller
Weighted Switch Controller

Suppose, I am adding some think time(Timers) in each HTTP request, but when I execute the test, in the report it shows response time as Sum of ThinkTime + actual response time.
How can I get actual response time from the result?
by default, JMeter does not include Timer's time in the response time of any HTTP sampler.
In case if you are using Transaction Controller to group the requests, then you can deselect the checkbox Include duration of timer and pre-post processors in generated sample in the transaction controller.
By default JMeter does not include the duration of:
Timers
PreProcessors
PostProcessors
into Sampler's response time unless you use Transaction Controller with Include duration of timer and pre-post processors in generated sample option selected. If this is the case and you use dynamic values in the Timer - you can consider using Sample Variables functionality to record think time into .jtl results file.
Think Time is the time taken by the user to read,
understand and take next action on the webpage.
So the time between a response and the net request
is the Think Time. This can be simulated by adding
a timer.
Constant timer I used but I confused with the execution of contestant timer. there are many request under one TR Controller so If I use contestant timer the given time will apply to all request of TR Controller.
Which Jmeter timer and how I should use to it in the real scenario while execution of jmeter execute.and make sure it should be exclude to the response time.
Pl see the below Image and imagine this is the my scenario.
Thanks a lot in advance
Please find the below screen shot to use the constant timer for each and every request.
You can use the constant timer for the services which ever you want.
Try this where ever you need to add the think time and execute, it will consider only for the requests(where ever you add that timer).
If you add it to the TR controller it will consider the think time for every request under controller.
The simple one is add a constant timer value 5000 at the level of HTTP Samplers

If above is Your Test plan
then Right click on ThreadGroup-->Add-->Timer-->constant Timer and provide value 5000
In this case the constant timer acts between each http request your are sending
i.e., it sends Login and waits for 5 seconds and it sends Login action and waits for 5 seconds and it sends Dashboard page and waits for 5 seconds and on and on ..
Note : The constant timer element must be sibling to HTTP sampler , but not as a CHILD.
please let me know if you required further info on this .If it helps click answered
My jMeter script performs visiting the Workout history page of the website.
While leading there the app sends 8 api requests. We put them into one Test Fragment but while running scripts in jMeter I get the response time of each HTTP Request.
Is there any possibility to get the response time of the whole Test Fragment?
My Test Fragment screenshot
It is simple. You just add a Transaction Controller in the Test Fragment. Move all the HTTP requests under the Transaction Controller.
If you are looking for only the total time of all the requests, then check the Generate parent sample checkbox.
you could definitely do this in beanshell, start a timer and then calculate the end time.
Also you might try something like the JC#gc package of extra plugins for something like responses over time.
I have written a load test for a web application. The test script submits a request to the server via HTTP and then polls the server in a While loop with a small timer, to see when the request has been processed. The problem I am having is that in all the listeners (aggregate graph, table, etc.) JMeter only shows the time each request took and not the total time to process the job, i.e. time from initial request sent until response that contains the expected "complete" message.
How can I add something like "profiling points" which will get data onto the listeners graphs? Or is there another way this is typically handled?
You need a Transaction Controller. Put elements times of which you want to aggregate under it. Transaction controller will then appear in all your listeners. Its load and latency times will be sums of those parameters of its nested elements.
Note that this time by default includes all processing within the controller scope, not just the samples, this can be changed by unchecking "Include duration of timer and pre-post processors in generated sample".
