HTML Reports generated with JMeter don't show requests grouped under a particular transaction. All requests and transactions appear in the HTML report Randomly. Is there a way to arranage those requests as part of transactions in the HTML Reports.
Is there any plugin which can do that, if this feature is not native to JMeter ?
Any pointers will be appreciated?
Try to give naming convention for requests as shown below:-
First, Script Name "SC01" then transaction sequence "00" "and then name for the request or action name. i.e.SC01_00_Homepage.
I hope this help.
For auto increment, initialize a variable let say "id" with 0 in the user defined variable then use ${__intSum(${id},1,id)} for auto increment as shown below:-
For reset, use jSR223 post processor in the last sampler to reset the id to 0 as shown below.
Below is the snapshot to verify this.
Hope it helps.

I am using JMeter 5.5 to put load on some webpages.
I have some webpage navigation flow recorded and I am using The Transaction Controller with the "Generate parent sample" checkbox checked to represent a webpage navigation (load). Underneath the Transaction Controller are the some HTTP Request samplers with "Retrieve All Embedded Resources" checked.
I want to ignore the first and last minute of script execution so I am using a JSR223 Postprocessor with code to conditionally ignore the samples based on the current time in the execution.
This works well if I don't use the Transaction controller, but when I use the prev.setIgnore() function and the sampler being ignored is underneath a Transaction controller with the "Generate parent sample" checkbox checked, then in the "View Results Tree" listener (and also in the JMeter Dashboard) I get an empty parent sample with Load time:0; Connect Time:0; Latency:0. This impacts my metrics in the final generated report.
Is there any way to ignore the Parent sample as well (remove it from the reporting) or can I achieve the goal in a different way?
Thanks in advance.
I think you need to replace prev.setIgnore() with prev.getParent().setIgnore()
In general ignoring samples with Groovy is not something I would recommend to do as it causes extra overhead, I would rather suggest using
either Filter Results Tool
or JMeter Plugins Command Line Tool
or use jmeter.reportgenerator.start_date and end_date properties in case of using HTML Reporting Dashboard
Guys I need to manually set the end time for the transaction controller in the jsr223 post processor
I tried the following:
prev.getParent().setEndTime()
SampleResult.getParent().setEndTime()
And it didn't help, getParent always returns null. Could you please help me? Maybe there are other ways to do it?
I use jmeter 5.4.1
enter image description here
In order to be able to set the time for the Transaction Controller you need to meet the following criteria:
Transaction Controller should have Generate parent sample box ticked
otherwise you will override response time only for the last child sub-sample. See Using JMeter's Transaction Controller article for more details.
I believe it's better to do it from JSR223 Sampler which should be placed after the Transaction Controller and the code in its turn should be something like:
ctx.getPreviousResult().getParent().elapsedTime=1234
I'm doing a performance test of a HTTP Patch Method Request using Jmeter called 'Update Person'. The case here is the Update Person is dependent on another request called 'Create Person'. Create Person will return a 'personId' as a response and I will use that id to send an update request. So I can't do a performance test with only the Update Person Request. Here is my Jmeter Test Plan Layout:
Jmeter Test Plan
When I run the test plan, the performance of both request is significantly slower than testing the Create Person alone. My questions are:
Does testing two http requests affects the performance? If yes, how?
Is there a way that I can test my Update Person request alone while the Create Person request is running in the background to get the personIds?
Thank you.
1.You can first run the create person alone and get all the required person ids in the csv. For this you can use the post processors and capture and write the output or take it directly from DB if it is there and you can.
2. Then, pass the created ids to the second request from the csv using CSV Data Set config.
Update:-
Use regex or any post processor for fetching the UserId then with in the same sampler use BeanShell PostProcessor to write the output to csv:-
Ex:-
CreatePerson = vars.get("Create_Person");
f = new FileOutputStream("C:/Users/XXX/Users.csv", true);
p = new PrintStream(f);
this.interpreter.setOut(p);
print(CreatePerson);
f.close();
This can also be achieved with Groovy for performance improvement. I am not an expert on Groovy but you can find that on this site. Dmitri T has submit that many times.
Then, for reading it is very easy. Add "CSV Data Set Config" before the samplers or on top to fetch the data. Column name need to be passed as variable where it is required like ${CreatePerson}
There is one more thing to capture the data instead of code. Use Sample Variable. In the user.properties(under bin folder) file add a line in the end:-sample_variables=CreatePerson
Then, use simple data writer or view result listener to save the results in the csv. It should write the data in the csv. You can deselect all the data that is not required from the simple data writer/view result listener.
Currently, I am recording a script in jmeter by which I am adding a record in a website , but a problem is that while recording a script I am able to add a record in a website, but once recording has been done and after that if I will run a script again then, a script is not adding a record in a website.
can you please help me with this?
In the absolute majority of cases you will not be able to replay the recorded script without performing correlation.
Modern web applications widely use dynamic parameters for session management or CSRF protection so once you record your test you get "hardcoded" values and they need to be dynamic.
Assuming all above my expectation is that your test doesn't add record due to failed login or something like that. Inspect requests and responses using View Results Tree listener - this will allow you to identify which exact step is failing.
The process of implementing the correlation looks as follows:
Identify the element which looks to be dynamic either manually inspecting request parameters and look for "suspicious" patterns or record your test one more time and compare the recorded scripts looking for the parameters which differ
Inspect previous response and extract the dynamic value using a suitable post-processor. For HTML response times the best option is CSS Selector Extractor. It will allow you to extract the dynamic parameter value and store in into a JMeter Variable
Replace hardcoded recorded value with the variable from the step 2
Repeat for all dynamic parameters
Don't forget to add HTTP Cookie Manager to your Test Plan.
Here i have A recording controller and test script recorder. I recorded the user activities using template. This automatically creates a Recording controller and then transaction controller. Each transaction controller has child HTTP request wrapped inside it. Now when I run the test after creating a test script, I see that the aggregated result shows information about (throuput, error, min etc) for child HTTP request(Sampler) as well as the parent transaction controller.
I'll make it more clearer with images below.
In the above picture ive created the test plan. Now when I run this test i get following result. The circled ones are the transaction controller.
Here, i have circled the parent transaction controller. Now why on earth is this adding up to the result.
Question: Is it making any request to the website? Why is this showing up and adding values to the child request. This thing is just a sum of all its child request - so, why is it adding up in the table?
Here again if I click on the "Generate parent sample" then it hides the child request and shows only the summed up report which is totally different from above report.
Now the question is how do I turn things around. What are the consequences. And what should I do in this case. Shall i compute the parent-child report or just the parent report data?
As per documentation of Transaction Controller:
The Transaction Controller generates an additional sample which measures the overall time taken to perform the nested test elements.
So if you don't want this additional sampler, just remove it or replace it by Simple Controller.
Note it is useful when it contains more than 1 sampler.
