JMeter Recording - All actions cannot be performed - jmeter

While recording a workflow through JMeter proxy, I am not able to click some items(like buttons), which otherwise are available when the website is getting loaded without JMeter proxy.
Now, needless to say, i have to click those buttons to perform certain activities essential as a part of the workflow whose performance I want to measure.
I am quite new to JMeter, so not sure how to proceed with the problem. Is there any Proxy settings i should change?
When I am checking the website source there is no difference between the page getting loaded via proxy and the page without it.
Please let me know if additional info is required. Thanks in advance!!!

Check jmeter.log file (usually lives in JMeter's "bin" folder or folder, you launched JMeter from if it's different) for anything suspicious. Log file should be the first place to look into as JMeter basically writes anything there.
You can increase verbosity if required by adding the next line to user.properties file (again lives in "bin" folder of your JMeter installation)
log_level.jmeter.protocol.http.proxy=DEBUG
Try cleaning your browser history, it's better to delete everything, especially cache.
Try re-installing JMeter certificate. See Installing the JMeter CA certificate for HTTPS recording chapter of the HTTP(S) Test Script Recorder (was: HTTP Proxy Server ) for instructions
If above steps won't help and you're absolutely sure you're doing everything right you can try raising a JMeter issue
Also be aware of JMeter Chrome Extension which is an alternative way of recording a JMeter test which doesn't require proxy server.

Jmeter Recording xml issue

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.

Why the application is throwing error when I execute a search transaction via Jmeter proxy, but not when I manually execute the transaction?

I am facing this problem, and I suspect it is security related.
I am using Jmeter corelation recorder to record my scripts for testing,
I tried recording a search transaction in my application which is a document management system and as soon as I search(after Login) , it throws an error, while when I run the functionality manually it runs well.
Should I try forcing Jmeter to use my local proxy for recording or even playback(I have developed the script with Blazemeter extension as the Jmeter proxy recording was not working) ? The script however fails to playback the search transaction, server returns a 500 error.
I also see that Blazemeter extension has no problem recording the search transaction, which makes me suspect, that probably a security certificate is missing when I try recording via Jmeter proxy.
Correlation recorder doesn't do any magic when it comes to identifying dynamic elements and coming up with proper regular expressions to handle them, you still need to do it manually prior to starting recording.
With regards to JMeter recording failing: yes, you need to import the JMeter's certificate into the browser, this way JMeter will be able to intercept and decrypt HTTPS traffic, see HTTPS recording and certificates chapter of JMeter's documentation on HTTP(S) Test Script Recorder for more details.
If you add View Results Tree listener and see the responses, most probably your login fails somewhere somehow hence search fails due to your virtual user fails to login.
So make sure that
JMeter sends the same network requests as the browser does
all dynamic values are correlated
HTTP Cookie Manager is added to your test plan
given all above criteria are implemented you shouldn't experience any problems.
There is a 3rd-party solution: BlazeMeter Proxy Recorder which seems to be capable of automatically detecting and correlating dynamic parameters, if you're new to this concept - even if it won't resolve your problem fully at least it will give you some clue.

JMeter HTTP Test Script Recorder randomly stops recording

I am creating recordings for a company website for performance tests. Normally this works fine though on occasion when starting a new test recording, HTTP Test Script Recorder will not record anything but returns the following error in the browser:
I have been using jmeter for a while now so I know the setup for HTTP Test Script Recorder is ok.
Clearing browser history, running in public or private mode doesn't help. Re-issuing jmeter proxy cert makes no difference either, the same for deleting proxyserver.jks.
Having experienced this before, I know that after a few days HTTP Test Script Recorder will start working again.
Happens for both jmeter v4 & v5.
I can think only of one situation when it can happen:
You have a JMeter test running in background (or a thread which failed to stop for some reason)
You're trying to record something at the same time
So
Make sure that nothing is running at the moment (you should see 0/0 in upper right corner of JMeter GUI)
Start clean recording session, to wit restart JMeter and create the test plan using Recording Template feature (From main menu choose File -> Templates -> Recording and click "Create"
Just in case be aware that you can also record your mobile application traffic using cloud-based proxy service, as a bonus you will get possibility to export recorded scripts in SmartJMX mode with automated detection and correlation of the dynamic parameters.

The issue you see is most probably a bug probably introduced by:
https://bz.apache.org/bugzilla/show_bug.cgi?id=57962
During recording, JMeter variables are null so we end up using an Unmodifiable version of them because of this:
https://github.com/apache/jmeter/blob/trunk/src/core/org/apache/jmeter/threads/JMeterContext.java#L88
I suggest you open a bug here, providing as much information as possible:
https://jmeter.apache.org/issues.html
Provide:
How you reproduce it
The jmeter.log with the stacktrace (not as an image)
The workaround is to avoid running a test and recording after that.
Edit on 3 december 2018:
You reported a bug:
https://bz.apache.org/bugzilla/show_bug.cgi?id=62916
The reproducer is:
Start a distributed test where Controller is in GUI mode and a jmeter-server
Once test is finished, start a Recording using HTTP(S) Test Script Recorder
Hit a URL, you'll get the issue
The bug has been fixed today, it will be available in JMeter 5.1 and is already available in:
https://ci.apache.org/projects/jmeter/nightlies/

jmeter proxy recording duplicate request

I am currently using JMeter to record a test scenario with the HTTP test recorder proxy.
Problem is, when I send a request with IE on my application, the recording controller gets flooded with an unlimited number of duplicate requests corresponding to the one I just sent.
Multiple requests when accessing default page
Any idea about why this could be happening is welcome.
Have a good day
JMeter's HTTP(S) Test Script Recorder should be accurate enough and if you see extra requests most likely they happen.
I would recommend double checking what's going on on network level between IE and application under test Using Windows Internet Explorer Developer Tools Network Capture.
If it reproduces in IE without JMeter proxy - it might be an integral part of your application, i.e. it does periodic polling for updates using AJAX calls which needs to be reflected in your load test as well.
If not - you need to find the reason why does JMeter behave this way starting from enabling debug logging for JMeter proxy. It can be done by adding the next line to log4j2.xml file (lives in "bin" folder of your JMeter installation)
<Logger name="org.apache.jmeter.protocol.http.proxy" level="debug" />
So after hours of setting comparison and http request analysis, I found out it was just the "type" parameter of the HTTP Test Script Recorder that needed to be set to "Java".
Hope this can help someone.
Don't forget to have a good day :-)

JMeter HTTP(S) Test Script Recorder

I am now trying to use Apache JMeter HTTP(S) Test Script Recorder, but I have a difficult problem!
I've done the following Settings in JMeter .
enter image description here
And I configured the proxy in firefox.
Then I recorded a simple script.
But when I replayed the script, it didn't work, and I got the following tips:
enter image description here
What should I do? Please give me some advice!Thanks!
I don't fully understand two things:
Why you are asking Badboy-related question in JMeter forum?
How it can be convenient to use 2 separate tools while JMeter has its own HTTP(S) Test Script Recorder?
So please retry recording using JMeter's Proxy Server and if the issue persists - come back here so we could take a look into the issue.
There is one more alternative solution for JMeter tests recording which used to work under any conditions: JMeter Chrome Extension, you can consider it as a fallback solution.
No one will ever read this or benefit from it, but just in case....
Right click your test plan and select Add > Listener > View Results Tree.
Re-run your script and read what's in the results tree.
