I have an application installed on my machine for learning purposes. Its URL is http://Localhost:8080/*****. JMeter fails to record the requests whenever I use the URL above. If I replace "localhost" with the machine IP, JMeter records without any issues. Loadrunner can record both URLs.
Is it a bug or is the JMeter proxy setting designed in that way?
Thanks...
JMeter doesn't filter loopback URLs, however you browser can do this, at least latest Firefox does:
As per How to Run Performance Tests of Desktop Applications Using JMeter article you might also need to install Microsoft Loopback Adapter
And last, but not the least, the application, browser and JMeter might be looking into different protocols: IPv4 and IPv6, you need to ensure that your localhost hostname resolves into the same IP address for all 3 components.
Latest version of Firefox by default does not allow localhost or 127.0.0.1 to be proxied.
After searching a lot online, finally the following steps worked for me:
Enter about:config in the Firefox URL bar
Search for config network.proxy.allow_hijacking_localhost using the search box and toggle its value to true
Now try recording scripts in Jmeter from localhost related webpages.
Note:
I am using Firefox 80.0.1 (64-bit) and Apache JMeter 5.3
I found reference from Setup JMeter proxy to record activities on a local web application
Please find the about:config page for Firefox browser below.

I can't able to record jmeter using with proxy server.
I tried proxy settings in RUN command jmeter.bat -H 192.168.61.202 -P 8080.
Jmeter is recording with the browser actions, but not connecting the internet.
Showing error page on browser.
See the screenshot- Error shown in browser
are you able to record it using normal browser mode? If yes you should check for the firewall and add the specific port numbers to exclusions as some time back I faced the same issue, after i added the port number to excluded in Inbound and Outbound rules and disabling the antivirus setup on my machine made it work
I am new to Jmeter and unable to record script using Jmeter. Eventhough I have followed the instruction provided by Apache.Jmeter.org. Pls update me with the few esay steps to move on.
Thanks,
Karthik.
If you are recording the script you can follow sequence,
Jmeter becomes your proxy and records everything between your real proxy and you so make proxy as localhost and port no as 8080 for http
if you are trying record a script for application running on proxy/local machine then above setup is enough
if you want to record script for a application on WAN then start jmeter like,
Jmeter - H "proxy which you are using" -P "port no" <-u "username" -a "password">
by default test plan is present when you start jmeter
add threadgroup and proxy recorder in script
start recording
If you have difficulties in setting up HTTP(S) Test Script Recorder (despite the fact it's perfectly documented in JMeter Proxy Step by Step guide you could try using Google Chrome JMeter plugin which allows JMeter scripts recording right from browser without needing to worry about proxies, browser extra configuration, SSL certificates, etc.
The most common error for using JMeter proxy is Do not use proxy for localhost / 127.0.0.1. If you have this or similar option in your browser make sure that it's disabled

I'm new to JMeter and I want to load test a local web application recording test case with JMeter proxy.
I've first followed instruction here http://jmeter.apache.org/usermanual/jmeter_proxy_step_by_step.pdf and all worked fine.
Than:
I launched my web application, say http://localhost:8080/my-application
Setup JMeter web proxy on port 8081
Added an HTTP Request Default to a Thread Group
Addea a Recording Controller
Invoked curl -X GET http://localhost:8081/my-application/index.html
I obtain:
Request are recorded but with wrong parameters, eg. https instead of http
I don't get the requested page with curl, but the exception: org.apache.http.client.ClientProtocolException: URI does not specify a valid host name: https:///my-application/index.html/my-application/index.html
The parameters I've specified in Http Request Default seems to be ingnored? I placed configuration element under HTTP Proxy Server, and tried many settings.
What's going wrong? I missed some basic configuration? I'm using JMeter Proxy in the wrong manner?
Firefox default setting will bypass "localhost, 127.0.0.1" from proxy so your JMeter still not able to record it. You have to empty the "No Proxy for" field, by removing the "localhost, 127.0.0.1". Hope this will help.
Firefox by default does not allow localhost or 127.0.0.1 to be proxied.
You have to modify a setting in about:config
change network.proxy.allow_hijacking_localhost to true
Go To Browser LAN Settings
Make sure "Bypass proxy server for local addresses" is unchecked so that request will hit JMeter proxy server.
Simple steps to be followed for recording in jmeter:
open ur jmeter (contains testplan and workbench in default)
add a threadgroup
add “http request defaults” whic is under config( change the server name i.ethe site u need to record)
add “http proxy server (workbench-rightclick-non testing elements-http proxy server)change the default port 8080 to
someother(eg 9090)
start the proxy server
change the browser settings to manual setup with 9090 port and localhost

I would suggest using Apache's own tutorial on this, it is located here...
JMeter Proxy Tutorial
I see that you say you have followed it, but it may have changed since you used it as some of your steps do not match the current tutorial. Perhaps your version had a bug or you missed a step, because I just double checked it 5 minutes ago and it worked for me and I don't see some of the steps you are talking about above.
I realize you have specific questions about specific errors that you are concerned with, but based on your current unfamiliarity with the process in general, I would abandon the curl part, and just do the basic proxy recording as Apache describes it to get a better general understanding, then take it from there.
The only caveat I would add to their tutorial, they have you create filters to only record certain types of actions, I actually leave those out so it will record all actions, then I just clean it up later.
This way you don't miss anything that could potentially be causing lag because that type of resource was filtered out.
* Now, one thing in your original question, you can try if you have no intention of doing the tutorial, try the browser, not curl, and setup your browser to use a proxy, and make sure the port matches the one you specify in jmeter on the proxy node.
Its very simple to configure. Please have a look to the attached screenshot.
I am learning JMeterProxy using WAMP and opencart web app.I did a recording using HTTP Proxy Server. I configured firefox and recording went smoothly. But if i am using IE, nothing seems to be recorded. I added a tree view listener in HTTP Proxy to log the recording, nothing is logged in it when i am using IE.
Some observations:
when i stop recording and if i try to access the local site using FF, it is not accessible, but in case of IE i could open the site.
If i browse an external site, recording is working.
I am accessing my site as http://localhost:81/opencart/index.php, since 80 port is used by IIS
My question is.
How would i trouble shoot this kind of scenario.
What changes i should i make in IE proxy settings.
I solved this problem, Here is the solution, as per JMeter documentation
If JMeter does not record browser URLs such as http://localhost/ or
"http://127.0.0.1/", try using the non-loopback hostname or IP address,
e.g. http://myhost/ or "http://192.168.0.2/"
So providing the host name in place of loop back address solved the problem
For example, I have a development site on a different server but I'm trying to copy content over from the live site so it'd be handy to have the live site in IE and the dev site in FF.
I tried FoxyProxy but I can't seem to get it to work.
I use this to override system's DNS with localserver
in about:config
change this value:
network.dns.forceResolve
network.dns.ipv4OnlyDomains
network.dns.localDomains
with IP address of local DNS server (for exsample 192.168.1.88)
Sorry for my english
It's now possible, with the DNS over HTTPS function:
Open Options, General, scroll to very bottom and open Network Settings,
On the very bottom, you can find DNS over HTTPS:
You had to use about:config before to change this setting, here's for documentation:
Type about:config in firefox address bar.
search for:
network.trr.uri
You can use one of the DNS servers below:
Cloudflare: https://cloudflare-dns.com/dns-query
Google: https://dns.google/dns-query
Secure DNS EU: https://doh.securedns.eu/dns-query
Quad 9: https://dns.quad9.net/dns-query
And set network.trr.mode to 1
Hijacked from here:
https://www.ghacks.net/2018/04/02/configure-dns-over-https-in-firefox/
It appears from your question that you already have a second set of DNS servers available that reference the development site instead of the live site.
I would suggest that you simply run a standard SOCKS proxy either on that DNS server system or on a low-end spare system and have that system configured to use the development DNS server. You can then tell Firefox to use that proxy instead of downloading pages directly.
Doing it this way, the actual DNS lookups will be done on the proxy machine and not on the machine that's running the web browser.
DNS resolving is usually done at the system level and not at the application level, so you can't normally have one program use one dns and another program use a different dns. I'm not aware of any firefox extensions that allow you to use a different dns.
What about having different names for your dev and prod servers? That should avoid any confusions and you'd not have to edit the hosts file every time.
I am using the SwitchHost extension exactly for this problem:
https://addons.mozilla.org/en-US/firefox/addon/14258
It is easy to configure, and even more easy to switch hosts.
I wonder if you could write a custom rule for Fiddler to do what you want? IE uses no proxy, Firefox points to Fiddler, Fiddler uses custom rule to direct requests to the dev server...
http://www.fiddlertool.com/fiddler/
Since http proxy protocol is similar to raw http protocol, you can redirect desired traffic to your development server by telling firefox it's a proxy server.
two limitations:
A. this won't let you use https connections.
B. some frameworks (e,g: wordpress) don't like this method and redirect the request the wrong way
just copy the following code into a .pac file (enter your site domain and IP address, of course), and switch development/production just by changing proxy configuration.
function FindProxyForURL(url, host) {
var prox4site = {
"mysite.com":"PROXY 10.0.1.100:80",
"www.mysite.com":"PROXY 10.0.1.100:80"
}
return prox4site[host] || "DIRECT";
}
Go to options->Advanced->Network->Settings->Automatic proxy configuration url and enter 8.8.8.8 All you Mozilla traffic uses Google dns now.
