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?

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.

Usecase:
User searches a product and validates the response time
User validates response time in pagination functionality of searched result.
To check pagination, we need to search. Should this be part of second test or jmeter doesn't require previous request like UI, can we skip this and only test the pagination request?
As per JMeter project main page:
JMeter is not a browser, it works at protocol level. As far as web-services and remote services are concerned, JMeter looks like a browser (or rather, multiple browsers); however JMeter does not perform all the actions supported by browsers. In particular, JMeter does not execute the Javascript found in HTML pages. Nor does it render the HTML pages as a browser does (it's possible to view the response as HTML etc., but the timings are not included in any samples, and only one sample in one thread is ever displayed at a time).
So if there are no dynamic parameters which store client state like ViewState or associated Cookies then you should be able to test the pagination without executing the "main" search request and only perform the correlation to see if there are more pages left, get the number of the current page, etc.
With regards to whether to put it under the Transaction Controller or not - it's totally up to you, Transaction Controller doesn't have any logic when it comes to "continuation" of the previous request, it just sums up the elapsed time of its children and reports the total amount taken.
I am using JMeter for image load testing.
I have an array of the image name and looping over that array, I am getting all the image via HTTP request.
-> loop_over_image - for loop controller
-> http_request sampler
for now, it will loop and fetch images via HTTP sampler one by one.
It is possible to make these request parallel.
I am looping over 300 images - means 300 HTTP request, it is taking more than 5 minutes, but in chrome, it is taking 30 seconds because chrome API requests are ASYNC - means kind of parallel.
Is there any way to make these 300 request parallel. I don't think it is possible, because the loop will go to each image one by one.
I am looking for the same solution.
I am extracting from an HTTP response a list of urls and assigning them into a variable (as array).
Parallel controller will not work in this case, since it does not accept an array as an input.
I think that there is not simple way to do it (possible using Java and JSR223Sampler).
JMeter dev community should add this feature to JMeter.
I've opened an enhancement request https://bz.apache.org/bugzilla/show_bug.cgi?id=63526
Please vote up on it, so it will be implemented.
Try with parallel controller or sampler.

Hope this helps.
I make a post call to an api, and don't need to log the response (post to google cloud pubsub), but after that i need to measure time it takes for the data to be processed and appear in another GET request (need to keep hitting it unless the response changes).
I also need to measure the performance under load. I tried JMeter but could not figure out a way to get what I wanted. Is there a way to do this in Jmeter? or some other tool that will let me do what i want
You can put your "another GET request" under a While Controller so JMeter will keep sending this request unless it will match some defined condition
You can put the whole sequence of requests under the Transaction Controller - this way JMeter will measure end-to-end duration of the whole scenario
i have a issue with to many calls to the server.
I have extracted several urls with the "regex extractor".
In the next step, a "http request" calls these urls by ${extractet-urls}
But all requests after the 8th url gets a error 500 response from the server.
I tried to input several timers between, before and everywhere else, but it hasn't an impact.
So my question is:
how can i delay in this single http request which calls all the extracted urls?
Thanks for your help :)
After the requeat you can add sampler ->Java Request. Then change classname to SleepTest and it'll wait 1 second (configurable)
Add a Constant Timer as a child of the HTTP Request sampler (see Scoping Rules for details) and provide desired delay there (in milliseconds). It will cause the relevant thread to "sleep" for the defined amount of milliseconds before executing the HTTP Request. See A Comprehensive Guide to Using JMeter Timers to learn more about using Timers in JMeter tests.
Another option could be using Test Action sampler to create a delay, it doesn't generate sample result so you won't see it in .jtl results file.
The final approach is depending on what you're trying to achieve and how your test is designed.
Alternatively, you can add a Thread Group and define a ramp up time, then put the request inside this group. The ramp up time takes the startup overload too.
Is this possible in JMeter to develop a test plan that will have result of first test (an ID) will be input of next test and so on in next test upto 4 tests because each test generates a unique ID and each of these IDs are dependent on each other. Each one is related as follows: submission ID > execution ID > both will generate completion ID with result pass or fail. These are REST API calls. I need to run concurrency users load testing. Finally I need measure latency, throughput from each test.
Between sampler requests, parse the api response using JSON post processor, assign it to ${variable_name} and use it in other requests.
It should look something like this.
Thread group
Userdefined variables
Http Sampler
Regex to get id
Http Sampler
Regex to get id
If you want to measure the response time of all the sampler have a simple controller as parent of all samplers
thank you for quick tip. I was able to get one step working by passing ID into a regular expression, but the same regular expression did not work for 3rd step. Let me give more details here. Basically first post command gives submission ID > I used that ID into regular expression > run a get command in next step with an URL something like '/../2ndStep/submissionId' > this is passed > I'm using the same regular expression in next get command with an URL something like '/../3rdStep/submissionId/executions'> this is supposed to give another executionId and it is failing for me. I'm not sure what I'm missing.
thank you all for suggesting working solution. But I need to do this different way to achieve the following requirement.
When I run POST command test on my REST API HTTP request using JMeter, it returns an ID in response. This ID will be used by other steps for completing the job. I'm currently passing ID into regular expression and using that in between the samplers of each step as it was suggested above and then measuring latency, but the GET steps which are dependent on that ID could take sometime to complete. So I can not put those GET steps into one thread because two of the steps are failing as they could take some time to complete. Is there a way to separate POST command from the remaining and start polling GET commands on the remaining steps automatically to remedy this. Bottom line is I need to measure latency of each step and throughput too. Please let me know if there is a way to achieve this in JMeter?
Thanks again,
