I am trying to load test for my web application. I followed all the steps as per JMeter guide. After that enable proxy server also using port number 8080.
Please take a look my proxy server description in Firefox:
Please check my JMETER Configuration
Output after did all configuration
I am new for JMETER load testing, hope you guys will help to solve this problem.
Remove localhost and 127.0.0.1 from "No Proxy for" area in Firefox
Since JMeter 3.0 default port for HTTP(S) Test Script Recorder is 8888 so you either need to switch it back to 8080 in the HTTP(S) Test Script Recorder or configure Firefox to use port 8888. See Bug 59006 for details
You will have slightly better JMeter configuration for recording if you use "Recording" template, from JMeter main menu choose File -> Templates -> Recording and click "Create".
The main problem is Firefox expects that you would have installed a trusted Certificate before listening for requests using proxy server (via your port number 8080 as quoted above). Note that this is a Trust issue. Firefox does not trust your requests.
To resolve this issue, see below steps:
In Jmeter, from "HTTP(S) Test Script Recorder" once you click "Start" button to start recording and listening to requests, Jmeter creates a temporary "Root CA Certificate" in your Jmeter "bin" directory/folder automatically.
This certificate has to be uploaded on Firefox to enable Trust.
Note that the certificate has validity of 7 days. See screenshot below:
Next go to your "Firefox preferences" and click "Privacy and Security" Tab, scroll down to the "Certificates" section and click "View Certificates" to upload the generated temporary CA Certificate in the previous step (step 1). See image below:
Click the "View Certificates" button to add the temporary Root CA Certificate generated above. Note that the CA Certificate is located in your Jmeter "bin" folder.
See the certificate in the bin folder below:
Upload the Certicate as seen in the screenshot below:
Finally, as soon as the Root CA Certificate has been added to Firefox successfully, go ahead and start recording your requests. Everything should be work without issue.
Cheers!
After adding the certificate to your browser you have to hit 'Start' on the recording on jmeter before you access your website on the browser.
For jmeter test recording, you've to follow this sequence-
Add jmeter test script recorder
Set up the proxy ( you've done till here)
Click start in test script recorder(you must click start only then your links(pages) will load in browser )
Add the certificate generated in jmeter/bin folder(you only need to do this once)
then you can browse using the firefox browser

started recording my test on macOS, with below steps and I am receiving BELOW RESULTS
1. ERR_PROXY_CONNECTION_FAILED
"If you use a proxy server…
Check your proxy settings or contact your network administrator to make sure that the proxy server is working. If you don't believe you should be using a proxy server: Go to Applications > System Preferences > Network > Advanced > Proxies and deselect any proxies that have been selected."

Jmeter certyficate should be valid till 2024, I have renewed certyficate, following this instruction -> https://stackoverflow.com/questions/64043676/cannot-update-jmeter-root-ca-certificate
BUT IN KEYCHAIN
**Expired: Monday, 26 December 2022 at 10:52:55 Central European Standard Time

4. am using Chrome browser
Delete the certificate from the keychain completely
Delete proxyserver.jks and ApacheJMeterTemporaryRootCA.crt files in "bin" folder of your JMeter installation
Clear your Chrome browsing history completely
When creating the recording test plan from the template use www.testla.com without any paths
When you start the HTTP(S) Test Script Recorder JMeter will generate new ApacheJMeterTemporaryRootCA.crt file. Default validity is 7 days unless you change proxy.cert.validity property
Import this certificate into your browser. At this stage I would suggest using Firefox instead of Chrome because:
Firefox has its own certificates storage and Chrome uses the system one
Firefox has its own proxy configuration and Chrome uses the system one
It would be also a good idea to exclude other domains than tesla.com from recording scope
Your recording should be successful
Also be aware of an alternative way of recording a JMeter test: JMeter Chrome Extension, in this case you won't have to worry about proxies and certificates
It works for now but, still seems not correct
When I set proxy.cert.dynamic_keys false and it finally started recording with some 200 statuses:
Use dynamic key generation (if supported by JMeter/JVM).
If false, will revert to using a single key with no certificate.
Defaults to: true
BUT SOME TESTS ARE STILL 443 because of cert
Response message:Connection reset
ensure browser is set to accept the JMeter proxy certificate
Tried your recommendations also uninstalled and installed JMeter again, cleared and using Firefox for now, cert is valid until 16.01.2023, I have set jmeter.properties file to “#proxy.cert.validity=365” (with hash) and I have checked Firefox -> settings -> cert view and there is 16.01.2023 so looks like again I have to uninstall and install again?
Is it correct that when test finished and I want to user browser + internet again I need to go to Firefox settings -> proxy and set back from manual mode (localhost 8888 + https) to no proxy?
If I stay with manual there is an error:
“The proxy server is refusing connections
An error occurred during a connection to www.tesla.com.
Check the proxy settings to make sure that they are correct.
Contact your network administrator to make sure the proxy server is working.”
I have set up a proxy server and trying to record a script by adding "http script recorder", but the problem is I am able to access a website but not able to login.
my website has been loaded but once I enter credentials and click on the login button then a website is not behaving, login button also not responding.
In case of any problems with JMeter first of all you should look at jmeter.log file, if anything goes wrong JMeter normally writes an error message to this log file which in majority of cases is enough to get to the bottom of the issue.
With regards to your problem, my expectation is that login normally uses HTTPS protocol and you need to perform some extra configuration so JMeter would be able to intercept and decrypt HTTPS traffic.
You need to install JMeter's self-signed certificate to your browser, the file is called ApacheJMeterTemporaryRootCA.crt and it's being generated in "bin" folder of your JMeter installation when you start JMeter proxy.
You just need to import it into your browser and it should resolve you issue. Follow your browser documentation to learn more about certificates installation processes, some hints are also given in the HTTPS recording and certificates chapter of the HTTP(S) Test Script Recorder JMeter User Manual entry.
Alternative way is using JMeter Chrome Extension, in this case you won't have to worry about proxies and certificates so the recording process will be faster and easier.
The current state of my JMeter setup and test plan is:
JMeter 5
Certificate Authority generated and imported into Firefox.
Checked that the port # in the HTTP(S) Test Script Recorder matches that in the proxy server set up in Firefox.
Have added a Recording Controller to my Thread Group.
Have added Cache and Cookie Managers to my Thread Group.
When I start the proxy server, i.e., Start the HTTP(S) Test Script Recorder, I can walk the example application I'm testing - including HTTPS requests. (And if the HTTP(S) Test Script Recorder is not started I get "The proxy server is refusing connections" message from Firefox.)
I have ensured that the selected Target Controller in the HTTP(S) Test Script Recorder is a recording controller I've added to my Thread Group.
No Sampler/Requests are being added under the Recording Controller.
Has anyone else encountered a situation in JMeter in which the proxy server seems to be working correctly but no sampler/requests are actually being recorded? And even if this case is novel, do you have any suggestions? Thank-you in advance for your advice.
Take a look at jmeter.log file - if there is an issue with your setup you should get some clues regarding what's wrong from there. It is also a good idea to add the next line to log4j2.xml file:
<Logger name="org.apache.jmeter.protocol.http.proxy" level="debug" />
it will increase log level verbosity for the HTTP(S) Test Script Recorder
Make sure your Firefox is configured to use the proxy for all protocols and there are no exclusions for localhost, 127.0.0.1 or your IP address/hostname
Try clearing your browsing history as it might be the case "stale" certificate is still present or something is cached.
As the last resort be aware of an alternative way of recording a JMeter test using JMeter Chrome Extension - in this case you will not have to worry about proxies and SSL certificates.
You shouldn't create your own Test Script Recorder script, simply because you can make mistakes, just use predefined JMeter's template
Choose Menu: File -> Templates
(Recording is selected) Click Create
Your Recording script is set
you need to add ApacheJMeterTemporaryRootCA certificate in your firefox by setting
Go to tools > option > Certificate > View Certificate > import certificates.
Now restart the firefox.
just a late reply but facing same issue...
Have you tried to clean the 'URL Patterns to include' in HTTP(S) Test Script Recorder ?
It did work for me and could record was the proxy was not recording.
Jmeter is not recording a particular site. However, it did record for the very first time, later something might have happened, below is the set up.
HTTP(S) Test Script Recorder > port 7878
Firefox > localhost (7878)
open firefox > start HTTP(S) Test Script Recorder and open WWW.xyzabc.com
Jmeter records perfectly as expected.
Now, after sometime i did the same, this time nothing is being recorded however, the site got opened on firefox.
Additionally, when i have stopped recording on jmeter, i was still able to open the site and perform actions on firefox, but for other sites i get "The proxy server is refusing connections"
Can anyone please explain this behaviour?
A couple of assumptions:
Your site uses HTTPS transport and Firefox isn't configured to record HTTPS traffic
Your site is running on your local machine and Firefox is configured to not to use proxy for local addresses.
In Firefox network configuration make sure:
Use this proxy server for all protocols box is checked
No Proxy for: input field is empty
If it doesn't help you can try out the following:
Add the next line to user.properties file
log_level.jmeter.protocol.http.proxy
Restart JMeter to pick the property up
Look for anything suspicious in jmeter.log file
If nothing help you can consider an alternative way of recording a JMeter test - JMeter Chrome Extension
Here is the step by step procedure to record a scenario in JMeter.
The easiest way to use recording is from "Templates" .
Step1: Open your Firefox browser and from Network Connection settings configure the proxy server as HTTP Proxy: 127.0.0.1, Port: 8888.
See image here
Step2: Run your Jmeter.bat file and open "Templates" under File dropdown list and click "Create".
See image here
Step3: Expand WorkBench and select "HTTP(s) Test Script Recorder". And click "Start" at the bottom of the page.You will have two pop up to Allow Firewall and Temporary Root CA Certification Installation.Allow all those and now go to your browser and do your browser activity.When it's done "Stop" the HTTP(s) Test Script Recorder.
Step4: After this you will get the recorded script in JMeter with all your activity in the browser.It will automatically update under Thread Group.This script will contain all your page requests during browsing activity. Sample script after recording is shown here.
If it's HTTPS, then you have to add its certificate to jmeter.
I'm new to jmeter, I'm facing an issue while trying to record on IE, after i enter URL and hit enter i get website’s security certificate error, when i try it without recording on JMETER it works fine. Can anyone please tell me how to over come this issue?
Steps followed:
I have launched jmeter using proxy or else i won't record anything,
Launched using: C:\apache-jmeter-2.13\apache-jmeter-2.13\bin>jmeter -H {myproxyadd} -P 8080 -u etc
LAN Settings:
Only use a proxy server for your LAN is checked and everything else is unchecked on LAN Settings.
Address: localhost port:8080
jmeter website’s security certificate.
This is expected. JMeter is using self-signed certificate in order to be able to record HTTPS traffic and Internet Explorer warns you that certificate is not "trusted". So you can ignore this warning, click Continue to this website (not recommended) and move on.
As per "Installing the JMeter CA certificate for HTTPS recording" chapter of HTTP(S) Test Script Recorder documentation.
As mentioned above, when run under Java 7, JMeter can generate certificates for each server. For this to work smoothly, the root CA signing certificate used by JMeter needs to be trusted by the browser. The first time that the recorder is started, it will generate the certificates if necessary. The root CA certificate is exported into a file with the name ApacheJMeterTemporaryRootCA in the current launch directory. When the certificates have been set up, JMeter will show a dialog with the current certificate details. At this point, the certificate can be imported into the browser, as per the instructions below.
Note that once the root CA certificate has been installed as a trusted CA, the browser will trust any certificates signed by it. Until such time as the certificate expires or the certificate is removed from the browser, it will not warn the user that the certificate is being relied upon. So anyone that can get hold of the keystore and password can use the certificate to generate certificates which will be accepted by any browsers that trust the JMeter root CA certificate. For this reason, the password for the keystore and private keys are randomly generated and a short validity period used. The passwords are stored in the local preferences area. Please ensure that only trusted users have access to the host with the keystore.
Documentation also suggests installing certificate into browser to make this warning go away:
Browse to the JMeter launch directory, and click on the file ApacheJMeterTemporaryRootCA.crt, and open it
Click on the "Details" tab and check that the certificate details agree with the ones displayed by the JMeter Test Script Recorder
If OK, go back to the "General" tab, and click on "Install Certificate ..." and follow the Wizard prompts
By the way, you can use an alternative to JMeter's HTTP(S) Test Script recorder service. It makes recording process easier and also can export recorded requests in so called "SmartJMX" form - automatic correlation of dynamic parameters.
