Unable to do recording Jmeter - jmeter

Im new to Jmeter . While doing the recording Im getting the below error . please help me

It looks like JMeter cannot access the Internet, most probably you're behind a corporate proxy server
If you want to record website(s) (or other resources) which are in the Internet - you need to make JMeter aware of the upstream proxy.
Normally your Internet connection looks like:
browser -> corporate proxy -> Internet
when you're recording with JMeter you substitute your corporate proxy with JMeter hence Internet access won't be available anymore:
browser -> JMeter proxy -> you can only access local resources
so you need to make it like:
browser -> JMeter proxy -> corporate proxy -> Internet
See Using JMeter behind a proxy user manual chapter for more information.
Additionally I don't think you should be recording requests to www.gstatic.com as it's Google's CDN so I believe you neither should record the calls to that site nor replay them as this is something absolutely beyond your control, moreover your IP address can get banned (unless you're a Google employee who has the task to load test the CDN). See Web Testing with JMeter: How To Properly Handle Embedded Resources in HTML Responses article for more information if needed.

JMETER recording issue with VPN

We are trying to record UI based Application in JMETER for the public network and made proxy settings accordingly in Firefox browse with valid certificate.
But with VPN, we could not be able to record that UI application and we are getting below error.
we made changes to proxy configuration too as suggested by our infra team in Firefox browser and in JMeter tool, but we could not able to record at all public network UI application.
There should not be any issue with recording the applications which are being the VPN because Java relies on operating system routing mechanisms in order to find the best way to the system under test.
Just make sure to start the HTTP(S) Test Script Recorder after connecting to the VPN and don't forget to import JMeter's certificate into your browser.
In case of any problems check what's in jmeter.log file - it should contain the failure reason.
Also be aware of an alternative way of recording a JMeter test: JMeter Chrome Extension, in that case you won't have to worry about proxies, certificates and VPNs.

Jmeter Script recorder with Firefox not letting user bypass Authentication

I have an issue I'm facing which Jmeter Script recorder and Firefox browser in Windows 10.
I have managed to add a project in Jmeter with the Recorder template and imported the generated
Certificate into the Firefox browser and also changed the proxy settings to point to the port
I have in Jmeter Test script recorder (8888) by changing the proxy to manual configuration.
But when I start recording I get to a point in where I need to authenticate myself at a certain point in a webpage (a prompt showing up) and I also enter the correct credentials but it just keeps redirecting back to the prompt all over again so I can't bypass it.
Are there settings I should change in some of the Jmeter properties files?
I need to say that the computer I'm trying this with has proxy settings which are fixed and cant be changed when looking into wifi settings in control panel
JMeter provides HTTP Authorization Manager to deal with external authentication types like
basic HTTP
NTLM
Kerberos
So if you want to record the end-to-end flow you need to add properly configured HTTP Authorization Manager to your recording template test plan. The configuration details will differ depending on the server configuration, see Windows Authentication with Apache JMeter article for more details (you will need this setup in any case for replaying the recorded scripts)
Alternative solutions:
Disable proxy for this particular login request like:
Record all the steps including login - it will produce relevant HTTP Request samplers
Disable proxy
Perform login
Enable proxy
Continue recording
Use a 3rd-party recording solution like JMeter Chrome Extension

Unable to record application running on local host in Internet explorer using JMeter Test script recorder

I am trying to do record a test script using JMeter (version 4) Test Script Recorder for performance testing of my application. After configuring the proxy, The recorder is not recording my application URL running on localhost in Internet Explorer (IE 9). But other URLs are getting recorded in JMeter. I tried to record my application using Chrome which is working fine.I have unchecked the Bypass proxy server for local address in Proxy settings.
I recommend you to use Mozilla Firefox to record your script because Firefox allows you to manage proxies and certificates independently of system settings.
Get more information about recording:
Apache JMeter HTTP(S) Test Script Recorder
JMeter Recording Guide
Make sure to check Use the same proxy server for all protocols box in the "Advanced" tab of the Internet Explorer proxy settings and there are no localhost, 127.0.0.1, etc. in the "Exceptions"
Some applications cannot route traffic to a local proxy server so you may need to add a loopback adapter
If you're recording an application which operates over HTTPS protocol you will need to install JMeter's self-signed certificate into Trusted Root Certification Authorities:
It doesn't really matter which browser you're using for recording as applications mostly differentiate the browsers basing on User-Agent header so you can record using whatever browser and then change User-Agent string in the HTTP Header Manager to IE9
According to JMeter Best Practices you should always be using the latest version of JMeter so consider upgrading to JMeter 5.0 (or whatever is the latest version available at JMeter Downloads page)

How to record using jmeter Http proxy server with "Automatic proxy configuration URL" (i.e .pac file )in proxy in browser

In Jmeter, I am not able to record any external website from our company proxy server.
I have to use option "Automatic proxy configuration URL" (i.e one .pac file )in to browser if I dont know how to configure it in Jmeter to do successful recording.
Any idea?
PAC fiels contain javascript which is executed by the browser to decide which proxy URL they want to use. JMeter is not a browser so it does not run this code. The solution is simply to resolve which proxy this script returns and input this value into JMeter directly, you can do this using the dev tools on most browsers, or just ask the IT dept. that maintains the thing to tell you the direct address.
Same question with solution in Jmeter mailing archive.

JMeter : How to record HTTPS traffic?

I'm using Apache JMeter 2.3, which now supports "attempt HTTPS spoofing" under the Proxy Server element.
I've tried this on several different servers, and have had no success.
Has anyone been able to successfully record from an HTTPS source with this setting?
Or barring successfully recording, can anyone share a work-around? When available, I simply have HTTPS turned off at the server level, but this is not always feasible. Thoughts?
Starting from JMeter 3.0 default port for the HTTP(S) Test Script Recorder is 8888
The easiest way to configure recording is using JMeter Templates feature. From JMeter's main menu select:
File -> Templates -> Recording -> Create
Don't forget to start the recorder :
In JMeter < 4.0, Expand "Workbench", if >= 4.0, ignore this step
Select "HTTP(S) Test Script Recorder"
Click "Start" button
You will see a message regarding Root CA Certificate. Click OK:
it is OK, it informs you JMeter has created a Root Certificate Authority that you need to import in your browser to be able to record correctly HTTPS traffic.
To Import this Root CA certificate in Firefox (it is located in jmeter/bin folder) for example:
Configure browser to use JMeter as proxy:
It is now Ok.
You can navigate to your application, samplers will be created under "Recording Controller" which is under "Thread Group" element
While the JMeter proxy already has the ability to record HTTPS requests, a Chrome Extension that creates JMeter script came out recently:
https://chrome.google.com/webstore/detail/blazemeter-the-load-testi/mbopgmdnpcbohhpnfglgohlbhfongabi?hl=en
It uses a BlazeMeter as the middleman (a commercial JMeter in the cloud service) but you can use their free service forever and still use the plugin to record a JMX script and download it locally to your own machine even if you never use any of the paid plans.
What I do is:
Go to my website using my web server's IP-address (i.e. http://2.2.2.2/login.html)
Start the recorder and run through my test case
Stop recording
Replace all values of the IP address with the domain name (i.e. replace 2.2.2.2 with yoursite.com) from the HTTP Request Samplers
Set the protocol to https in the HTTP Request Samplers
If you have more than a few pages, it's easiest to create an HTTP Request Defaults item, and set your domain name and protocol there.
FYI, I'm using the latest stable build as of 2010-05-24: Jmeter 2.3.4 r785646.
The newest version of Jmeter (2.4) now supports HTTPS recording. Rejoice!

Is there any other way to record HTTPS than Bad boy and Https spoofing?
Yes--use a nightly build of JMeter, e.g. version r922204.
Https recording is successfully working in new version of Jmeter 2.9 as of today. I had to import proxy certificate and play around with Firefox to get this working.

Https recording using Jmeter
Yes, I have used it with "attempt HTTPS spoofing" on. Things are simple enough:
Turn HTTPS Spoofing on (of course).
Make sure that the browser sends Http request to Jmeter, so that Jmeter can record it and then send the encrypted request back to the server. So, the URL in the browser should start with http:// (and not with https://). The details could be found in my blog.
Please let me know if it works for you.
I am using Webscarab to record https and ajax conversations.
It workd fine. I extended the Webscarab with export function for Jmeter.
