In my jmeter script, I want to apply a logic where I take the time stamp of the first request and the second last request with the last request being logout. The difference in the time stamps when exceeds 3600 sec should trigger the logout transaction. I can take the time stamps using the jmeter _time function but not able to subtract it successfully. If I can get this done then I can put logout in an if controller and give the condition. Can anyone help please?
Check out __longSum() function which you can use to subtract 2 Unix timestamps
Define start as: ${__time(,start)} where required
Define end as: ${__time(,end)} where required
You can get the difference between end and start as ${__longSum(${start},-${end},)}

I am using a while loop to run a API request until a specific response is recieved (eg. Job status). Now, I want to calculate time taken for a job to reach that status. I want to generate a report with jobID, status and the time taken. Is there a way to do that? Any help on this will be highly appreciated.
enter image description here
While condition that i am using: ${__jexl3(${__jm__While Controller__idx} < 300 && "${Status}"!="Ready",)}
Put everything under the Transaction Controller, it will return the cumulative time of all its children execution

I would like to get future / past date in my Jmeter. I tried timeShift but it returns milliseconds by default, I would like to use it in seconds because my system does.
I have tried many ways but can not figure it out. Can you all show me how ? Or other methods ?

Use __timeShift() and __jexl3() functions combination
with __timeShift() you will get the date in past/future in milliseconds since start of the Unix epoch
and with __jexl3() you can simply divide the resulting value by 1000 to get the value in seconds

In your timeShift call, edit the 'time format' parameter to '/1000'. Something like ${__timeShift(/1000,,P2D,,)} (to get a shift of 2 days in seconds).
I have jmeter test plan in which I create a workflow which transitions statuses like Not Started to In Progress to Completed.
The problem I am having is how I can measure how long it took for workflow status from the time of creation to it get completed? Since we are logging the response time of api calls only.
Is there a way we can extract this info and also add it to the summary (jtl reports?) I was thinking if I could do it from beanshell post processor where I have the wait time calculated and also checking the status of workflow and I could write to the summary result (jtl). How can I do this?
I have the test plan set up something like this:
Thread Group
- Create Workflow API call
- WhileLoop(checking on a flag set by beanshell post processor)
- Wait for 5seconds
- Check for timeout using JSR223 sampler(java)(don't want test to run inevitably if something goes wrong so want to break the loop after a fixed amount of time)
- Get Workflow status API call
- Beanshell post processor to check the response from above call to see if status is Completed or wait time has exceeded. In either of these cases I set the while loop flag false if not repeat the loop wait for 5 seconds and so on.
For the test itself it works as expected.
Use transaction controller to measure the time taken. Please check the reference;-
The Transaction Controller generates an additional sample which
measures the overall time taken to perform the nested test elements.
Hope this helps.
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
