I created a JMeter recording. But when I start the Test,
I don't see any request going in Fiddler. I changed the
port number in Fiddler to 8080, that I am using in JMeter.
Steps:
Create a Thread Group
Add Http Request to the Thread Group and enter URL
Add Recording Controller to the Thread Group
Add HTTP(S) Test Script Recorder
Change Firefox settings to localhost proxy and 8080 port
Record Test
Then start Fiddler and start the test
I am not sure whether JMeter is really running the test successfully.
However it is showing the number of users as 10 and no errors when I
run the test. Is there anything that I am missing?
First, change Fiddler's port back to 8888 as it was originally.
Next, change JMeter's proxy settings to point at 127.0.0.1 on port 8888 as its proxy settings.
Then, run your test.
To record traffic from JMeter via Fiddler use the next setup
Importent
I used JMeter 5.0
Recheck that your Fiddler listing port set to 8888
UI Mode
Create Thread Group --> HTTP Request
Go to Advanced fill "Server Name or IP:" = 127.0.0.1 , "Port Number:" = 8888
Non UI MODE
Add to your command -H 127.0.0.1 for Proxy Host
-P 8888 for Proxy port
Example:
C:\jmeter5.0\bin>jmeter -n -t C:\example.jmx -l C:\scriptresults.jtl -H 127.0.0.1 -P 8888
I would not suggest using fiddler as JMeter has its own recorder now.
To record a series of requests you need to follow the below steps.
Open JMeter
Right-click on 'Test Plan' and navigate to 'Threads (Users)' under 'Add' menu and then choose 'Thread Group'
Now, right-click on 'Thread Group' and navigate to 'Login Controller' under 'Add' menu and then choose 'Recording Controller'
Now right-click on 'Test Plan' again then navigate to 'Non-Test Elements' under 'Add' menu and then click on 'HTTP(S) Test Script Recorder'
Now without making any changes, click on the start button in the right section and then move to your browser.
Now configure your browser to use the proxy
Host: localhost
Port: 8888 (You can change this if you have changed the same in JMeter but make sure both have same values)
Now browse the internet as you normally do.
The above procedure will enable you to record traffic without hassles.
Remember, this will work for websites without HTTPS only.

I am using JMeter with an authenticated proxy e.g.
jmeter -H 10.12.12.5 -P 1080 -u myuser -a password
In Fiddler I've done a Rules->Customize as below where xxxxxxxxxx is the base64 encoding of my username:password:
if (!oSession.isHTTPS)
{
oSession.oRequest["Proxy-Authorization"] = "Basic xxxxxxxxxx";
}
Also under Tools->Options-Gateway I've set Manual Proxy and entered the proxies as:
http=10.12.12.5;https=10.12.12.5
However when I playback the traffic from JMeter Fiddler is not picking it up.
Man, you pointed both JMeter and Fiddler to use some 3rd-party proxy, there is no any connectivity between them, if you want to see JMeter's traffic in Fiddler - you need to:
Configure Fiddler to use the 3rd-party proxy
Configure JMeter to use Fiddler as the proxy something like:
In Fiddler Tools->Options-Gateway http=10.12.12.5;https=10.12.12.5
In Fiddler Tools-> Options - Connections - Fiddler listens on port - check the value, the default is 8888
Run JMeter to use Fiddler as the proxy like:
jmeter -H localhost -P 8888
You might need to import Fiddler's certificate into JMeter or vice versa
And last but not the least, you can use JMeter's HTTP Header Manager to send this Proxy-Authorization header
More information: Configure Fiddler as Reverse Proxy
I had follow all the below given Steps.
Please check and suggest me solution for this.
1.Create Thread Group.
2.HTTP Request(with Port 8080 and IP/Server Name as localhost.
3.HTTP Request Defaults(with Port 8080 and IP/Server Name as localhost).
4.Added Recording Controller.
5.Under Workbench created HTTP(s) Test Script Recorder
6.Updated URL patterns (.*.html).
7.Added View Result Tree.
8.Clicked on Start and install Root CA certificate(Click OK).
9.Set a Proxy in Firefox.
10.Firefox Option Advanced Network Setting.
Check the Manual Proxy Configuration.
HTTP Proxy: localhost and Port: 8080.
11.Check the "Use this Proxy Server for all Protocol".
No Proxy for "localhost".
Finally I have did not see any script that has been recorded.
You Can Follow these below steps:
Open Jmeter.
Click on Templates... (File->Templates... )
Just Click on "Create" button.
Then open up your Firefox browser.
Then Open Menu-> Options -> Advanced -> Network -> Connection Settings.
Then configure just like this.
Then just click OK.
Start the HTTP(s) Test Script Recorder from Jmeter.
9.Now Install Root CA certificate.
Restart your Firefox and you are just ready to record your test script.
You will find your recorded script under the "Recording Controller" section!!
Hope, this will help you. :)
It might be the case you're trying to record secure (HTTPS) traffic.
Make sure "Use this proxy server for all protocols" box is checked
Make sure "No Proxy for" box is empty
You can also consider an alternative recording approach - JMeter Chrome Extension - in that case you won't have to worry about proxies, SSL certificates, browser configuration, etc. - click one single button and you're all set.
- In step #2, You don't need to specify anything in HTTP Requests, HTTP requests will
be added automatically when you record your script successfully.
- In step #3, DO NOT use server name as "Localhost" and port number as JMeter's port.
Only when you want to test HTTPS domains, you specify HTTPS as a protocol.
Also, if you are testing an application that requires a specific port number (Example:
htts://somedomain.com:9595/somepath/) you specify the Server/IP Name and the PORT in the
HTTPS Default.
- In step #5, you specify JMeter port number (8080 or 8888 or...), and chose "Target
Controller" to "Use Recording Controller". You will find recorded script in Recording
Controller when you expand it after recording is done.
- In step #10, use the same port number you specified in step #5.
For me, the solution was to create an alias for 127.0.0.1 in /etc/hosts:
127.0.0.1 myserver
and create the JMeter script from the Recording template as detailed at https://jmeter.apache.org/usermanual/jmeter_proxy_step_by_step.html, specifying "myserver" as the host (instead of www.example.com).
Also, if your backend listens on a specific port, you have to specify that port in the "HTTP Request Defaults", under "Port Number".
My web application doesn't uses browser. It is a MS Word plugin and uses port 80.
When I try to record on port 80, Jmeter says 'port already in use'
And if i set other port in my app, app doesn't work properly.
What to do in this case??
Thanks
If your MS Word Plugin has proxy settings - configure it to use JMeter's Proxy.
If it doesn't have its own proxy settings - it should respect system proxy configuration (usually it can be configured via Internet Explorer proxy settings)
You can use 3rd-party tool like Wireshark or Fiddler to capture the traffic and convert it to JMeter .jmx script.
The only way you can do it as I see it is not through script recording but by setting requests in jMeter manually and build whole test plan like this. It's not so hard anyway if you know how your plugin works and requests you send. Some short info can be find here:
http://jmeter.apache.org/usermanual/build-web-test-plan.html
Error message 'port already in use' means that port 80 was assinged to some other service. You can't assign that port to Jmeter proxy server to start. (Jmeter has to start its own service on some unused port)
a. Just start Jmeter on its default port 8080 (or some other unused port).
b. Redirect required traffic to Jmeter proxy port (i.e, 8080). MS office will honor System proxy settings, so change the IE proxy setting to server '127.0.0.1' port '8080', it should automatically apply to office.
c. Now all the HTTP requests trigger from Office should visible in Jmeter Proxy recorder. After that you can move them to required location in Test Plan.
As Dmitri Said, you can also use Fiddler to track the requests (Prefer Fiddler over Wireshark, for its ease of use).
Good Luck!
How to do performance testing of localhost url which is accessible only to my computer?
I am able to do performance testing using jmeter for live websites like google etc but jmeter is not able to detect local url.
URL of application-192.168.121.20:8001
2. Output of View Results Tree listener- ALL failed http alerts Description of screenshot of HTTP Request sampler- added only server name i.e URL –
I have the same problem, but my mistake is that I thik the Server Name was the URL Base and it is not works.
This is the wrong way:
Server Name: "localhost/api/v1" (Wrong)
Http Request -> Path: "/auth"
Http Request Defaults (Jmeter):
The correct way:
Server Name: "localhost"
Http Request -> Path: "/api/v1/auth"
Http Request Defaults (Jmeter):
Http Request (Test):
JMeter doesn't care whether application under test is local or remote, if you cannot hit local URL with JMeter - something is wrong with your HTTP Request Sampler configuration, most likely "Port" value is wrong.
In order to be able to help we need to know the following:
1. URL of your application
2. Output of View Results Tree listener
3. Contents of JMeter log
4. Description of screenshot of your HTTP Request sampler
As an alternative option you can try recording your scenario using JMeter Chrome Extension and see if you're able to replay recorded scenario without errors. Again, use View Results Tree listener to inspect request and response details.
In general it is not recommended to run the application under test and the load generator on the same physical or virtual machine as the load generator (JMeter in your case) may consume immense amount of resources like CPU and RAM and it may interfere your application health (unless you're using completely isolated containers), so I would recommend use separate hosts for application and the load generator.
For anyone testing localhost with JMeter for the first time, make sure endpoint are configured correctly.
For a Get request of http://localhost:8080/rest/comments, set:
Server Name or IP: localhost
Port Number: 8080
Path: /rest/comments
Method: Get
please note that i have attached images for each step
Step 1 : First create Thread Group .After Create thread group you will see three part.
Number of thread means how many requests you want to perform and loop count means how many time you want to execute
Step 2 : right click on the thread group Add --> Sampler --> http request as like attach image .In the name filed just give a name as like whats you want.In my case it was Order Service http request
In protocol filed i am going to http request so for that i have given http in the box
In the server name i have set it to localhost because i am using local machine .If you use just remote server then use Ip address or domain name . Don't use http or port number before or after the ip address or domain name
In the port number field i am using 9003 that's why I have given 9003 .
In the http request field use your desired http method in my case i will post some data so i am using POST method so that i have selected post method
Path field just use the path after the ip address or domain name or localhost in my case it was order/create-order . please note that do not add forward slash before that. slash will automatically added by JMeter.
As it is post request so My server side request some body data so i have attached that as json format so click on the body data
step 3 : Sometimes you need to pass some header information for example content type . for that you need to create another option HTTP header manager to create that option . Right click on the thread group then add-> config element- > http header manage as like attach image . I have given the content type
Step 4 : Now you are ready to for request to server but sometimes you need to check the response and other thing so for that click on the thread group then add -> listner -> view result tree
Final Step : To execute the request, click on the greeen button from the top bar.
In order to have Jmeter "recognize" localhost (and any other program on your machine) you have to modify host file:
On Windows
Typically host is located under C:/windows/system32/drivers/etc/. Just open it with any text editor.
Add following record to this file and save changes:
127.0.0.1 localhost
On OSx
Open /private/etc/hosts file for editing with any text editor
Add following record to this file and save changes:
127.0.0.1 localhost
As a result you'll map localhost to your computers default local IP address which is 127.0.0.1
Get your ip addres using ipconfig (windows)
Think your URL is - http://192.168.8.149:3000/api/user/showTeams
Use Server Name or IP -192.168.8.149
Use Port Number - 3000
Use Protocol - http
Use Path - api/user/showTeams
Use IPv4 address instead of using localhost or 127.0.0.1 to access your local application.
Get JMeter's recording template from File > Template.
Set proxy on 8888 port and start recording
In my case, I was running a web app using local Tomcat on port 8080. JMeter was unable to connect using localhost:8080/app-name. It was connecting just fine to the remote-host:8080/app-name.
Solution: I found out that there was another application accessible using 127.0.0.1:8080/another-app. Perhaps, this was confusing JMeter. So, eventually, I changed my tomcat port to 9090 using server.xml and then JMeter was able to connect to localhost:9090/app-name
for your path use http://[::1]:{port}/route
[::1] instead of localhost fixed this for me, took me hours to figure that out
I would like to run a verticle at port 8080 on the localhost so that when I configure Firefox to use http://localhost:8080 as proxy, it will connect to the verticle and I should be able to get the URL that was requested.
In other words, whatever URL I type in my address bar(say www.google.com), that should be available in the verticle. My ultimate aim is to get the html at the URL, inject some script of my own and serve it up to the user.
Currently when I run a server at 8080 Firefox simply responds that Server didn't respond.
Also I am unable to println anything when I type a URL(like google.com) which seems to suggest a connection was never made. Instead when I type localhost:8080 I get a proper response as well as the absoluteURL.
Odd.. If you run the proxy example in the vertx-examples repository:
https://github.com/vert-x/vertx-examples/blob/master/src/raw/groovy/proxy/Server.groovy
That starts the proxy on port 8282. If you then go into the Firefox preferences:
Preferences -> Network -> Connection Settings
And set the HTTP Proxy to localhost, the port to 8282 and check the checkbox Use this proxy server for all protocols
Then typing google.com into the address bar should show logging in the terminal window, and the browser should display:
server-data-chunk-0server-data-chunk-1server-data-chunk-2server-data-chunk-3server-data-chunk-4server-data-chunk-5server-data-chunk-6server-data-chunk-7server-data-chunk-8server-data-chunk-9
Maybe it's cached something in the browser? Try clearing the caches before navigating to google?
