We are performing load testing using JMeter, we have to calculate the time taken by each page, but each page has multiple requests. Should we add transaction controller to find out the overall time taken by each page or should we calculate time taken by each sample in JMeter?
Transaction Controller isn't the case,it should be used to group several samplers
Transaction Controller generates an additional sample which measures the overall time taken to perform the nested test elements.

There are multiple requests in the test plan created for ride booking process. I need to find the time taken between the login and the ride booking apis .Is there a way wherein I can get these details in the test plan automatically without any manual intervention?
Most probably you're looking for the Transaction Controller, it generates synthetic Sample Result with the response time which is the sum of all its children

I am using Jmeter 5.2, the application i am testing i have split them transaction modules. When i execute the test plan, the elapsed time, latency and connect time were added together for a module in the aggregate report. Since some of the requests runs parallel in a module, that report didn't produce expected results.
Later, i have moved the request to bzm-parallel controller modules. Where, some of the requests fails since some of the requests has to be executed after the previous request.
Is there any way to calculate the exact timetaken for the execution of 1 module in Jmeter considering the parallel execution of requests?
Cumulative execution time of parallel requests equals to the execution time of the longest request so you need to take only that request which elapsed time exceeds its neighbors.
In order to filter out "not interesting" requests you can use one of below optoins:
Put parallel requests under the Transaction Controller
If you're using HTML Reporting Dashboard for results analysis you can consider jmeter.reportgenerator.exporter.html.series_filter property
You can remove the samplers you're not interested in via Filter Results Tool
You can use a Simple controller inside your Parallel controller. This will help you execute the samples in parallel and in the correct sequence as arranged in the simple controller.
Sample:
Parallel Controller
Simple Controller
-- HTTP Sample 1
-- HTTP Sample 2
-- HTTP Sample 3
Output:
HTTP Sample 1
HTTP Sample 2
HTTP Sample 3
I am executing a JMeter script for 25 users i.e threads and I wish to know much time it took for each user to perform the particular action (i.e. perform the complete usecase). My intention is to be able to give an average time so to say that if 25 actual users do this function simultaneously in the real environment then the average time it will take is that amount of time. So I wish to know whether there is a feature in JMeter may be a listener that will enable me to get this statistic.
Transaction Controller is something you're looking for. It measures cumulative time of its children so you will have both individual actions timings and the total time of all actions.
Results can be visualized using i.e. Aggregate Report listener

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 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".
