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.

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
In JMeter, I can load test many pages using a random variable:
/path/item/${random_var}
I would like to hit each page X number of times (or until a condition is met). I would also like to wait (e.g. 1 second) in between requests for a specific page (it's fine to have concurrent requests for /path/item/1 and /path/item/2).
Any guidance on setup for that is much appreciated. I can answer clarifying questions if needed.
Add a Constant Timer as a child of this request and set Thread Delay to 1000.
Timer will be fired before each request therefore you will get a 1 second delay between next call. Sleep time will not be added to sampler's response time (unless you are using Transaction Controller configured to do so)
See A Comprehensive Guide to Using JMeter Timers for more information on above and other Timers and their use cases.
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.
I have a http request with a BSF postprocessor script where I try to collect some data from the request. I have 10 users who call this request. I want to add a small delay between each request and I tried using a constant timer. The problem I have is, sometimes 2 or 3 HTTP requests are executed at the same time and that causes some logic disturbances in my postprocessor script. I tried using a constant throughput timer and still I end up with the same result. What is the correct way to send requests at constant time intervals?
A timer is specific to each thread so what you are tring to do will not work.
If you want to ensure your query is only executed by 1 user then use Critical Section Controller:

Thanks for the responses. I was finally able to achieve it just by increasing the ramp-up time. Thanks Mario for your quick response.
Need some help on Jmeter for the following scenario please I need to simulate these steps in order to load our application.
a) make a request to a web-service.(done)
b) verify the response for some variables and extract a URL address from the response.(done)
c) Now using the extracted URL need to make another request.(extraction done)
d) in response a media file will be sent.
My Plan consists of "stepping thread group-->(Sampler 1)HTTP Request +couple of listeners for data gathering--> (Sampler 2)HTTP Request +couple of listeners for data gathering. the issue is that when i ran the plan the first sampler generated 4 requests but the second one generated only 2 can you tell me why is it so.
In general how can i simulate all 4 steps in one go for a single thread. I hope that i have cleared myself.
In JMeter each thread runs requests sequentially already.
So in order to do what you expect you'll need to use:
Post Processors called extractors to extract data into variables
Variables to inject in the requests
