I am using Jmeter to test a web page. Obviously it has css, images, js etc. How can I group the response times by css,js and images so that I can clearly see the response time broken by resource types.
You pose an interesting question. The listeners in JMeter show what's at the sibling/child level. Therefore, instinctively, if you want just one type of resource in a given report, you'd need to put all the requests in a single controller and give that controller a listener.
You can get around restructuring your test by renaming your samples in a consistent manner. Something like: "CSS - actual request name".
Then, using Aggregate Report, you can copy the results into a spreadsheet, sort by name, and get your metrics that way.
I think you can use parallel controller to group the type of static files, ajax, etc. And use a transaction controller to group the page you would like to request, under the transaction controller you can add the parallel controller as hierarchy.

While doing performance testing via JMETER, I encountered one usecase where the POST request call is taking the dynamic data from the website. So in that case when we run our script it fails as that data is no more available on the website.
Payload looks like given below. It is a POST CALL and the payload is changing everytime.
{"marketId":"U-16662943","price":{"up":98,"down":100,"dec":"1.98"},"side":"HOME","line":0,"selectionids":["W2-1"]}
Could anyone suggest how we can make this payload dynamic when we create a script in JMETER?
I can think of 3 possible options:
Duplicate data is not allowed. If this is the case you can use JMeter Functions like __Random(), __RandomString(), __counter() and so on
The data you're sending needs to be aligned with the data in the application somehow, in this case you can use JDBC PreProcessor in order to build a proper request body basing on the data from the application under test database
The data is present in previous response. In that case it's a matter of simple correlation, the dynamic values should be extracted from the previous response using suitable Post-Processors and variables needs to be sent instead of hard-coded parameters
I am running performance test using JMeter 5.0 and then at the end of the test a HTML report is generated. I would like to know if there is anyway to view actual request with the endpoint it served what was the response and ability to view all requests in HTML report. I know JMeter has something called view result tree and it provides most of the information i need but i am not sure how to display result tree or something similar in HTML report.
View results is tree is rather resource intensive listener so you want to use it with caution. Typically you want to filter and display only errors so you can analyse them.
If you would like HTML reports then you can use a modular extension for JMeter. Its default behavior is to read and process samples from CSV files to generate HTML files containing graph views. It can generate the report at end of a load test or on demand.
You can generate the HTML report using menu item Tools → Generate HTML report:
This page explains different configs and options to tweak and tune the report generation.
Hope this helps.
As of current JMeter version 5.2
JMeter can only generate the HTML Reporting Dashboard from the CSV files
The dashboard generator is a modular extension of JMeter. Its default behavior is to read and process samples from CSV files to generate HTML files containing graph views. It can generate the report at end of a load test or on demand.
There is no possibility to store response data in CSV mode:
response_data is currently not supported for CSV output
So there is no easy way to implement your issue unless you use i.e. Flexible File Writer to store request/response data into a separate file and modify report-template (you will need to learn FreeMarker) to display the information you need.
use this command, -g .jtl file -o reportlocationpath, you will get nicely generated html report along lots of graphs as shown below:
I would like to know if there is anyway to view actual request with
the endpoint it served
My guess is that you already have all the metrics required for each request but would like to see individual request payload and the response. Just in case this guess is wrong, since you already have the report and are still not able to see the individual requests, I am assuming that you have checked on "Generate Parent Sample" across each Transaction Controller. Uncheck that and you should be able to see individual request level response time, 90th percentile etc. Of course you will have to re-run the test to get these individual request level values
However, if you want to literally see the request payload and response in HTML report, there is no way we can do that. Only View Results Tree can do that for you within the scope of JMeter's GUI and not outside of this.
what was the response
As mentioned above, as of today, there is no possibility to see the response of individual requests along with their payload in the HTML report and this is for a good reason. We do not require the requests/responses while we run a load test in our HTML report. It is necessary for debugging and until the script is ready for execution. But post that, we wouldn't require the responses. If you still want to ensure that the correct responses are received, you can always add assertions (although best practice is not to add too many assertions in a load test)
Just an example of why HTML report across any load testing tool will not show responses of a request -
Assume there is a load test of 10K users for 10 iterations and the Thread Group has around 10 transactions each having an average of 7 requests, there is going to be 7 million responses to go through. Having this in a HTML report is not just tedious but literally doesn't make sense.
I know JMeter has something called view result tree and it provides
most of the information i need
The View Results Tree is the holy grail for debugging and for ensuring if requests and response are appropriate during script creation stage.
I think your primary concern is to ensure the correctness of the responses rather than get the whole response of each request. In that case, as I had mentioned above, you can always use assertions. Several other custom alternatives include capturing specific parts of response and writing them to a file or something like that by leveraging JSR223 sampler or using the if controller to validate. Of course this is going to add some overhead on JMeter depending on the type of test and script that you are going to execute
but i am not sure how to display result tree or something similar in
HTML report
But if you still insist on having something in HTML and if I have failed to convince as to why this is something that one must not pursue, you can capture the entire response of each request in a variable through Regex Extractor and write them to a file with HTML tags in it. However, you will have to implement logic to collate responses and organize them for your need.
One more way would be to have the JTL save all data and modify this up in some text editor and beautify it with HTML
FYI on JTL and its configuration
Hope this helps!
Differentiate between GET and POST method in Laravel cake Controller REST API
There is concept of REST. REST is an architectural style and a design for network-based software architectures.It is not much specific on Programming language based.
Follow this thread.

GET requests a representation of the specified resource. Note that GET should not be used for operations that cause side-effects, such as using it for taking actions in web applications. One reason for this is that GET may be used arbitrarily by robots or crawlers, which should not need to consider the side effects that a request should cause.
POST submits data to be processed (e.g., from an HTML form) to the identified resource. The data is included in the body of the request. This may result in the creation of a new resource or the updates of existing resources or both.
GET - Retrieves Information (For eg: Providing response with some lists of data
from the database)
POST - Consumes provided resource and do the specified actions (For eg: Storing
form data in the database)

I have a question regarding graph for child requests of HTTP request sampler.
I am making a request to home page and including option of request embedded resources.
In response I am getting home page and also some css and js files.
Now I need a way to add graphs for those child requests(css and js files ). In response time graph, I can see only one graph for home page.
Is there a way to add these fields to graph along with home. are there any third party plugins you guys are aware of.
Thanks for your response.

Based on what I read at http://jmeter.apache.org/usermanual/component_reference.html#HTTP_Request, I believe that when you tell it to request embedded resources, it encapsulates this as part of the request, so the response time you see is the overall response time, and I don't think you can easily do what you want. That said, you can use various post processors to extract the URLs of the embedded into variables items and then do requests for them individually, though it's a pain.
In my test plan I have a series of steps like Login, HomePage, DoSearch, DoTask, Logout and each has a number of HTTP requests. I have tried using Simple Controllers, Transaction Controllers, keeping transaction controllers within simple controllers, and vice versa but am unable to see the timings at a step level in any graph. It at the most shows me the timings for Login, but other requests are not grouped on either controllers. Tried checking "Generate Parent Sample" and "Include duration..." but no luck.
Can someone let me know what needs to be done here?
You need to add a Listener. Each listener provides different information. I usually just use aggregate report.
