I have a post request and the response is success
Initially, I was able to execute the jmeter script and get the correct response but from today Im getting the below issue while testing a portal even though there is no changes made in the portal.
Im not understanding were am I going wrong. Kindly help me
Most probably you recorded your test using HTTP(S) Test Script Recorder and the recording included some hard-coded Cookie or Token
Initially it was working because the Cookie or token was active and "today" is expired and cannot be used anymore.
Basically it means that your script is missing correlation, you need to:
Identify the dynamic parameters used in your test
Use suitable JMeter Post-Processors to extract them into JMeter Variables
Replace recorded hard-coded values with the JMeter Variables from the previous step
See Advanced Load Testing Scenarios with JMeter: Part 1 - Correlations article for more information and examples if needed.

I am trying to do some basic performance testing on an app I look after.
I am using Jmeter and done the steps recorder and the same as following Jmeter tutorials on youtube, but I am getting stuck when I need put the variable into the X-CSRF-Token
The issue is I cant find X-CSRF-Token in the captured steps. Is it using some other form of authentication? Any suggestions for me as to other methods would be great.
If the post doesn't make much sense, I don't really have an in-depth knowledge of Jmeter or testing.
To find where the token appeared:
clear browser history
record your scenario using jmeter recording template
then in the view result tree located un HTTP(s) Test Script recorder, use the search field to find the first response in which it appears. You’ll need to add an extractor in the corresponding sampler
you ‘ll then be able to inject it using ${varName}
Depending on your server configuration this X-CSRF-Token can come in:
In the response HTML body
In the response headers, inspect HTTP Header Manager for any hard-coded values
As a HTTP Cookie (which is basically a header as well, however it will be much more convenient to get it from the HTTP Cookie Manager rather than from response headers)
So make sure to inspect all the tabs of the first request in the View Results Tree listener as this X-CSRF-Token guy can hide anywhere.
You can try an alternative way of recording a JMeter test, it can export test in "SmartJMX" mode with automatic detection and correlation of any dynamic parameters including but not limited to CSRF tokens so theoretically it can make your life easier, check out How to Cut Your JMeter Scripting Time by 80% guide for more information and technical details.
If you need further help you will have to provide more details, like full dump of 2 requests along with responses. You can use a sniffer tool like Wireshark or Fiddler to capture it.
I'm new to using Jmeter tool.
I have recorded my application using blazemeter (v3.1) and then trying to run that .jmx file in Jmeter, however I am running into an authorization issue and the script fails to run.
I have also tried setting my "HTTP Authorization Manager" with username, url, password but it does not help. If anyone can, please guide me on this Issue. Thanks.
As per 4 Things You Should Never Do with Your JMeter Script article:
Don’t run the script exactly as you recorded it
After recording your script, there is still some work to do before you run it. It’s necessary to correlate variables, parameterize and add elements, to faithfully simulate users.
There are too many ways of possible authentication implementation in your application, most probably you need to send some dynamic value along with credentials which can be fetched from the previous request.
Record your test scenario 2 times and compare recorded requests. Be careful as differences might be in response headers and URL, not only in response data. It makes sense to add View Results Tree listener directly to HTTP(S) Test Script Recorder - this way you will be able to see what data is captured by JMeter and amend its configuration so simulated request would look exactly like the request from the real browser.
i am using the govt site.
after correlation facing the issue as "HTTP Status 500 - Unable to do Single Sign On or Federation" facing this while replaying the script in Jmeter. suggest me how to handle this. your suggestion so valuable for me.
It appears that you are trying to load test application which uses Federated identity, most likely SAML .
It means you won't be able to record and replay your test scenario without performing advance correlation of dynamic parameters. Correlation stands for process of extracting the dynamic parameter from previous response using Post-Processor, saving it into a JMeter Variable and adding as a parameter to the next request so your Test Plan should look like:
See How to Load Test SAML SSO Secured Websites with JMeter article for detailed JMeter configuration of the extractors and variables.
I'm trying to test a few functions on my Laravel based website. However, I'm having difficulties logging in the website. I've used BlazeMeters Chrome plugin to record my events and save it in jmx file. Was able to do that and imported the file in JMeter. Now at login we are not just examine the email and password, but also a _token variable. This is individual for all visitors. Do I need and if yes, then how can I fetch the token for one user and use that at login time and any other time, when the _token was requested?

Your test flow should look like:
Open Login Page (usually HTTP Get Request)
Extract the token from the response using one of JMeter's Post-Processors (normally people use Regular Expression Extractor or CSS/JQuery Extractor)
Perform Login (usually HTTP Post Request) providing credentials and the token from the step 1
The process is known as correlation and there is a plenty of information on it over the Internet.
If you want to get things done faster you could consider an alternative way of recording a JMeter test scenario which automatically detects dynamic parameters, generates the relevant post-processors to extract them and store into JMeter Variables and substitutes parameters with the variables so you won't have to do it manually.

I am getting the following error while searcing for an entity after successful login
Full authentication is required to access this resource unauthorized
I tried to correlate the items in response headers (VCAP_ID, JSESSIONID) but nothing works. I also observed that the
"sessionToken":"Undefined"
Please provide resolution.
First of all try adding HTTP Cookie Manager to your Test Plan
Double check your correlation post processors using Debug Sampler and View Results Tree listener combination to ensure that all variables are properly extracted. The latter one allows inspecting request and response details as well and has i.e. RegExp Tester mode allowing validating your Regular Expressions against server response without having to re-run the request
If after all you won't fell comfortable with handling dynamic parameters in JMeter you can try out an alternative option of JMeter scripts recording which is capable of exporting the recorded test in "SmartJMX" mode automatically detecting and handling any dynamic values.
