To the left of the screenshot, I'm executing two 2 HTTP get requests (Same URL) marked in yellow. but as you see in the right side the Get request was executed only once and skipped the second time.
what am I doing wrong here?
Please check this screenshot
JMeter shouldn't "skip" requests, I can think of the following reasons:
You're running the test with more than 1 thread (virtual user) in the Thread Group, if this is the case - the sequential order of requests execution will not be guaranteed, you will need to add __threadNum() function in order to be able to distinguish the responses coming from different virtual users.
An error preventing the request from execution occurred, if this is the case - most probably the reason is in jmeter.log file (you might need to increase JMeter logging verbosity in order to get more information)

I have a script in which I have 30 to 40 http samplers and say for sampler number 10 I'm getting like 80% samplers response as blank or null, due to which rest of the samplers below it are also getting impacted as the result of variable not getting extracted in the post processor.
The response time at the 90th% for the 10th sampler is around 25sec.
I want to know is there any thing which I can do in the script to avoid this blank issue or is it something which app server is sending as the result of not able to bear the load.
Will changing the response timeout in the HTTP request default to higher value say 5 Min will resolve the issue?
Please help
Thanks.
You might be interested in Extractor Success Assertion plugin which checks whether the variable(s) declared in the PostProcessor(s) still have(s) default value(s) and if nothing has been extracted - it fails the relevant Sampler.
So you could use any other "Action to be taken after a Sampler error" than Continue in your Thread Group to decide whether you want to start new iteration or stop the thread/test when the response is blank.
Extractor Success Assertion plugin can be installed (and kept up-to-date) using JMeter Plugins Manager
I am trying to generate a test report for a thread group.
I see that since i run a http request in while loop controller, the request shows up in the report with too many failures as i also have an assertion to the request.
These are not failures but, tries, how do i make sure that these dont get captured in the report.
I am using View results in table listener for report. I tried to remove assertion for this http request so that it is not captured in the report? Is this the right approach?
As per 9 Easy Solutions for a JMeter Load Test “Out of Memory” Failure article:
Use Assertions Sparingly
Every test element added to the test plan will be processed - and this takes CPU time and memory. This also applies to all your Assertions, and is especially true for Compare Assertions - which consumes a lot of resources and memory. Only use the assertions you need and, even then, just use the amount that are absolutely required.
So removing the assertion seems to be a right approach to me.
Also if it's a Response Assertion you can modify it to accept 2 (or more) criteria so you can configure it to not to fail on "tries", example setup which accepts HTTP Status Codes 200 and 501 and will fail for everything else:
I have a single thread group which has 3 requests and have set the Number of Threads(users) = 2.
I would like all the requests to be executed in sequential order for each user before it repeats these steps for the next user and so on.
Output expected:
HTTP Request 1_Thread 1
HTTP Request 2_Thread 1
HTTP Request 3_Thread 1
HTTP Request 1_Thread 2
HTTP Request 2_Thread 2
HTTP Request 3_Thread 2
However, the output results vary differently for each run and are not in the order I expect. How can this be corrected?
I have tried following but with no luck in achieving my output
1. Enable/disable "Run Thread Groups consecutively
2. Running the test in non-GUI mode
I have attached a screenshot as an image as I am not able to embed into this message yet.
Appreciate if anyone can help me with this query
Thanks

For execution of Sampler Request by only Single Thread at a time use Critical Section Controller.
For more info about Critical Section Controller Critical Section Controller
The Critical Section Controller ensures that its children elements (samplers/controllers, etc.) will be executed by only one thread as a named lock will be taken before executing children of controller.
Critical Section Controller takes locks only within one JVM, so if using Distributed testing ensure your use case does not rely on all threads of all JVMs blocking.
Practical Example:
Place all your request under Critical Section Controller
Run the test for any number of Threads you want
Observe the Result in View Results Tree
Note : If you want to run it sequentially from 1 thread to N, make sure you provide Ramp Up Period properly.
I encountered a problem in Jmeter.
I have a scenario that I need to check, and it is to send the exactly the same http requests multiple times.
the request will not get any answer.
the problem is that Jmeter do it only once, it not even try to perform it in the second time.
I put it in a loop and still only once,
is their any solution? how can I make jmeter to perform multiple http requests.
for manual solution I use postman and send the same requests over and over again manually.
Is their any solution? I put the test plan, junk 1 + 2 + 3 are just the same call without any change, and the response is just 200, why Jmeter not run the http more than once?
[][test plan junk 2 + 3 not do]
[][loop controller set to forever]
[][all the junks are the same]
[][response of junk is 200ok nothing more]
[][no junk loop or 2 + 3 calls performed ]
[][logs]
Came across this while debugging the same issue - our problem was the "Use Cache-Control" option was ticked under "HTTP Cache Manager". This stops subsequent GET requests being processed, without an obvious warning or message.
Looking into red 1 near the yellow exclamation sign there is an error presumably connected with junk2, check out jmeter.log file for details, you should be able to identify the reason from there.
Also check your Thread Group settings, especially Action to be taken after a Sampler error parameter, if it is set to Stop Test or Stop Test Now might be a good explanation.
Normally people go for While Controller in order to repeat certain step(s), it allows to define condition(s) to exit the loop.
I record and run the Jmeter script by keeping number of users = 1, in tread group.
Results tree output:
I increased the number of users to 3 and result tree output order changed.
Therefore my some of regular expression exacter logics get failed and resultant responses failed. How can I avoid this situation.
Is there way to manage result tree execution order.
If your regular expressions are under the requests and not at the same level as of HTTP requests then it should not be a problem.Every thread/vUser will run independently. But, in view results you will see request as and when executed by different threads and not in sequence.
As per JMeter Functions and Variables user manual chapter:
Variables are local to a thread
Each JMeter thread (virtual user) executes Samplers upside down (or according to the Logic Controllers). JMeter threads are absolutely independent from each other and each thread has its own variables.
So the problem must be somewhere else, inspect the state of the variables using Debug Sampler and the response data for /oauth calls - it might simply not contain the necessary token value.
Also there is a suspicious call to bundle.js, my expectation is that you should not be executing it directly. The good practices is to configure HTTP Request Defaults to download embedded resources and use parallel pool to be closer to what real browsers do.
See Web Testing with JMeter: How To Properly Handle Embedded Resources in HTML Responses article for more detailed explanation.
