I have recorded a script, successfully via Blazemeter Chrome Extension. But now, would like to identify the dynamic values to be correlated. Is there a way to view the recorded responses? It becomes very difficult otherwise.
Regards,
Ajith
I don't think BlazeMeter Chrome extension can store the responses, the options are in:
You can enable requests recording in Chrome Developer Tools and export requests/responses as HAR
You can switch to JMeter's HTTP(S) Test Script Recorder, if you add View Results Tree listener and configure it like
the recording.xml file will contain all request and response data
There is an alternative option of recording a JMeter test: BlazeMeter Proxy Recorder, it has nice feature of exporting recorded tests in "SmartJMX" mode with automatic detection and correlation of the dynamic parameters, see How to Cut Your JMeter Scripting Time by 80% article for more details.

For performance testing testing Jmeter UI - endpoint - response time deferring from developer tool loading time
Ex Jmeter - endpoint response time is 615 Ms where in developer tool shows (Load: 13.30 s) Finish: 18.98 s
Note : Jmeter capturing 35 backend call/ Developer tool capturing 104 backend call
why jmeter couldn't capture all developer tool backend calls?
why jmeter couldn't capture all developer tool backend calls? do we have any solution for this issue
As per JMeter project main page:
JMeter is not a browser, it works at protocol level. As far as web-services and remote services are concerned, JMeter looks like a browser (or rather, multiple browsers); however JMeter does not perform all the actions supported by browsers. In particular, JMeter does not execute the Javascript found in HTML pages. Nor does it render the HTML pages as a browser does (it's possible to view the response as HTML etc., but the timings are not included in any samples, and only one sample in one thread is ever displayed at a time).
So apart from configuring JMeter to behave like a real browser when it comes to handling embedded resources, cookies, think times and so on you need to pay attention to the nature of the requests which are being called when you open the page in the browser.
If the request is created by JavaScript, i.e. it's an AJAX call JMeter won't make the request automatically when you open the page. However you can record it using JMeter's HTTP(S) Test Script Recorder and run after the main request. The cumulative response time can be measured using Transaction Controller
Check the Retrieve All Embeded Resources in Advanced tab of the http sampler and see what is the difference.
Times will be always slightly different between dev tools and Jmeter or between JMeter and other performance tools like Gatling for example.
I am trying to record a script for web application (https protocol)using jmeter-5.3. The xml file in the view result tree of HTTP(S) Test Script Recorder is capturing all the calls. but once I finished my recording and check the xml file doesn't have the calls(the first 3-4 transaction calls) in the beginning of the script in the xml. why its happening and how can I fix it?
According to JMeter Best Practices you should be using the latest version of JMeter so consider upgrading to JMeter 5.4.3 (or whatever is the latest version which is available at JMeter Downloads page)
Check "Grouping" setting of the HTTP(S) Test Script Recorder, it might be the case you have Store 1st sampler of each group only selected and it can discard important requests:
Make sure to use Recording Template as it generates good and valid recording test plan
Check jmeter.log file for any suspicious entries
Try alternative way of recording a JMeter test i.e. JMeter Chrome Extension and see whether all requests which should be captured are captured.
Is there an script recorder for JMeter (jmx) in which No Correlation is NOT needed. Just like "TruClient" Protocol in LoadRunner.
The script created with TruClient does not require any Correlation.
Thanks
There are few options available.

TruClient is not a "protocol", LoadRunner just launches a real browser (a headless one) and controls it.
JMeter equivalent would be WebDriver Sampler, if you're looking for recording solution for Selenium the options are in:
Selenium IDE
JMeter Chrome Extension
However be informed that real browsers are quite resource intensive, for example Firefox 95 needs a CPU core and 2 GB of RAM per instance so for 100 users you will need 101 CPUs and 200 GB of RAM which is kind of expensive.
Moreover:
As per WebDriver Sampler introduction
Note: It is NOT the intention of this project to replace the HTTP Samplers included in JMeter. Rather it is meant to compliment them by measuring the end user load time.
As per Selenium documentation
Performance testing using Selenium and WebDriver is generally not advised. Not because it is incapable, but because it is not optimised for the job and you are unlikely to get good results.
So I would recommend keeping your test on HTTP protocol level without browsers involved, if you have problems with implementing correlation - take a look at BlazeMeter Test Recorder capable of exporting recorded scripts in "SmartJMX" format with automatic detection and correlation of dynamic parameters.
I am new to jmeter. Creating a simple script seems easy via browser actions recording. Can that be done without launching the jmeter IDE?
As per latest stable JMeter version 5.4.1 it's not possible to start HTTP(S) Test Script Recorder without starting JMeter GUI
If you cannot do this for any reason the options are in:
Use JMeter Chrome Extension
Use your browser developer tools to record your test request into a .HAR file, once done you can:
either use online conversion tool to convert .har file into a JMeter script
or manually create JMeter's HTTP Request samplers by looking into requests details in the browser developer tools. If you cannot launch JMeter GUI at this stage as well you can consider using Taurus automation framework which allows creation of JMeter test plans using YAML syntax
You need to start the JMeter proxy for recording the test and it is not possible to start the proxy through available options.
There is a number of ways available for building test plans including the HTTP(S) Test Script Recorder.
Ten different ways to build JMeter Test Plans
The recording feature can be used even for complex scripts. You will have to use/add JMeter components and configure them once the recording is done to achieve the desired user actions.
I am pretty new to load testing and whole web thing.
Is there any way to implement things that this Vugen Loadrunner code do
web_custom_request("action",
"{URL}",
"Method=POST",
"Resource=0",
"RecContentType=text/html",
"Referer={refURL}",
"Snapshot=t57.inf",
"Mode=HTTP",
"Body={PARAMETER}",
LAST);
In jmeter? The {PARAMETER} is just a String.
JMeter's equivalent would be HTTP Request sampler.
JMeter's Variables have a little bit different syntax so the equivalent configuration would be something like:
If you want to have full control there is also HTTP Raw Request sampler which can be installed using JMeter Plugins Manager
Also be aware that you can record your LoadRunner script using JMeter's HTTP(S) Test Script Recorder, just start JMeter's HTTP(S) Test Script Recorder and in LoadRunner's Runtime Settings set JMeter as the proxy:
When you run your LoadRunner test JMeter will capture the requests and save them under Recording Controller
More information: How to Convert LoadRunner Tests to JMeter
To send any kind of HTTP Request you can use HTTP Request Sampler
To start with use this practical example : build-web-test-plan and then move to advanced build-adv-web-test-plan

This is a massive antipattern for success in this field. You need your foundation skills vetted and shored up. You really do need training and a mentor for a period of time.
If your management is asking you to perform in this role, then they should also ensure your path to success. If they are unwilling to fund your training and mentoring period, then I would recommend seeking new management who are more interested in your success and the success of the project.
