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!

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 need to extract static content(js, css, png) from the response and trigger dynamic http requests with static content.
Can you please let me know if there is any efficient way to extract and pass it http requests.
For example:
From below tags, Need to extract value from src of tag and store it in list/array and trigger dynamic request based on the number of values.
script asp-add-nonce="true" src="/abc/jquery.js"></script
script asp-add-nonce="true" src="/abc/xyz.min.js?v=skjdfjkdjfdfjlkjlkk"></script
In the above example, we have two values matching the condition, so we need to trigger below two dynamic requests.
If we have 5 tags matching condition, the need to generate and trigger 5 requests in JMeter.
http://appname/abc/jquery.js
http://appname/abc/xyz.min.js?v=skjdfjkdjfdfjlkjlkk
Appreciate if anyone can help on this.
JMeter can automatically parse response and look for images, scripts, styles, fonts, etc.
All you need to do is to tick the relevant box under "Advanced" tab of the HTTP Request sampler
More information: Web Testing with JMeter: How To Properly Handle Embedded Resources in HTML Responses
Alternative option is extracting them using a suitable Post-Processor and run the requests using ForEach Controller if you need sequential requests or Parallel Sampler if you need to send the requests at the same moment.
I'm currently testing a asp.net application. I have recorded all the steps i need and i have noticed that if i remove some of the parameters that i'm sending with the request the scripts still work and the desired outcome still happens. Anyway i couldn't find difference in the response time with them or without them, and i was wondering can i remove those parameters which are not needed and is this going to impact the performance in any way? I understand that the most realistic way of executing the scripts should be to do it like a normal user does (send all which is sent with normal usage) but this would really improve the readability of my scripts, any idea?
Thank you in advance and here is a picture which shows for example some parameters which i can remove and the scripts still work this is from a document management system and i'm performing step which doesn't direct the document as the parameters say but the normal usage records those :
Although it may be something very trivial like pre-populating date and time in calendar in user's time zone I believe you shouldn't be omitting any request parameters.
I strongly believe that load testing should mimic real user as close as possible so if it is not a big deal to send these extra parameters and perform their correlation - I would leave them.
Few other tips:
Embedded Resources (scripts, styles, images). Real-browsers download these entities so
Make sure you have "Retrieve All Embedded Resources" box checked
Make sure you "Use concurrent pool" size 3-5 threads
Filter out any "external" stuff via "URLs must match" input
Well-behaved browsers download embedded resources but do it only once. On subsequent requests they're being returned from browser's cache. Add HTTP Cache Manager to your Test Plan to simulate browser cache.
Add HTTP Cookie Manager to represent browser cookies and deal with cookie-based authentication.
See How To Make JMeter Behave More Like A Real Browser article for above tips explained just in case you want to dive into details
Less data to send, faster response time (normally).
Like you said, it's more realistic to test with all data from the recorded case, but if these parameters really doesn't impact your result and measured time, you can remove them for a better readability.
Sometimes jmeter records not necessary parameters because they are only needed for brower compability.
I am using JMeter for load testing and using listeners for getting the response results but I am not sure which are the most commonly used listeners which will give data for analysis.
I know Table view and tree view but those basic ones, kindly advice which listeners should I use.
JMeter documentation provides a very good overview of the listeners and when/how to use them.
While you are debugging and developing your plan, there's nothing better than View Results Tree, which also serves as a tester for RegEx, CSS/JQuery and XPath tester. However this particular listener must be disabled or deleted during the real load test, as it will eventually crash JMeter with OOM exception.
During the real load test you need to record statistics (how long requests took, etc.) and errors. In non-interactive mode, the best is to use Simple Data Writer with CSV format, which is considered to be very efficient. If you use interactive mode, or both (interactive and non-interactive modes), it's very convenient to use Aggregate Report or
Summary Report, since they display stats right away, and you can see immediately if something goes wrong. They also have ability to write to file, just like Simple Data Writer.
Finally, if you want to include some custom result collecting (not provided by any listeners), you can use BeanShell Listener or BSF Listener
In terms of organization, I find it convenient to separate successes and failures, so I always have 2 listeners:
For successes (in "Log/display only" option Successes is checked) I either record only statistics using Aggregate/Summary report (if test will run interactively and for a long time) or record file in CSV format (if I need a raw data about each request).
I always record failures (in "Log/display only" option Errors is checked) into file in XML format (for example using Simple Data Writer). XML format is not that efficient, but test is not supposed to have many failures (if it does, basically it should be stopped and analyzed). But XML format allows to record failing request and response headers and body, which is convenient for further debugging.
Hope this helps.
While executing the test better to avoid adding the listeners, only thing you can add simple data writer alone from that listeners you can generate any type listeners as you need.
while making the script ready you can use any type of listeners that will no be any issues.
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.
