We are trying to test large file upload scenario in JMeter.
When we upload a file with size of 15MB, it will break into 3 chunks (each chunk has 5MB).
I could see separate request in developer tools for each and every chunk going to the server with chunked data. I hope this chunking mechanism is something handled at the client side but not in server.
It would be a great help if anyone helps to achieve the same in JMeter.
Thanks in Advance..
You can mimic this behaviour using HTTP Raw Request sampler
Install HTTP Raw Request sampler using JMeter Plugins Manager
Capture the real request from the browser using a sniffer tool like Wireshark
Copy and paste raw TCP stream into "Request data" input field
That's it, now you should be able to replay the request using JMeter exactly as it is. You might need to perform parameterisation/correlation
Check out The JMeter HTTP Raw Request Sampler - When and How to Use It article for more detailed information if needed.

I have followed below steps to upload file in jmeter but it didn't worked. It throws Sorry, an error occurred while trying to execute your request. Please try again I have attached screenshots for more details.
Enabled Use multipart/form-data
Copied the file which is going to upload in /bin directory
I have tried with check/Uncheck Use multipart/form-data but no luck
In my HTTP request I passes action_id=1203 as Query parameters and in Form Parameters I am Passing other parameters like msgId, fieldId etc. but from screenshot you can observe when I execute that it passes my whole form parameters in just one single key of "msgId" I don't know why?
This are the headers which I pass
My Request with Query and Form parameters
File upload tab of http request
After execution request failed with this output. Here it passes all form params in single "msgId" key
F12 - Network request of Webpage form parameters (checked manually on web it works fine. Problem is in my jmeter request)
Just record the file upload using JMeter's HTTP(S) Test Script Recorder and it will generate the relevant HTTP Request sampler and HTTP Header Manager configuration which can be later on correlated/parameterized.
The only thing you need to do is to copy the file you're uploading to "bin" folder of your JMeter installation before recording. File path can be changed to whatever you want afterwards.
Also according to JMeter Best Practices you should always be using the latest version of JMeter so consider upgrading to JMeter 5.5 (or whatever is the latest stable version which is available at JMeter Downloads page) as soon as possible.

I'm trying to upload .xlsx file using multipart/form-data request type,
however, I'm getting different errors such as:
multipart body length limit 16384 exceeded;
unexpected end of stream, the content may have already been read by another component;
These are parameters for POST request that should upload our .xlsx file:
screenshot_1
Method: POST;
Use multipart/form-data checkbox: unchecked;
File Path: C:\temp\5000Lanes.xlsx;
Parameter Name: file;
MIME Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet
MIME type value is specified for .xlsx file types - https://www.freeformatter.com/mime-types-list.html;
These are Header Manager parameters
screenshot_2
Content-Type: multipart/form-data; boundary=--AaB03x
Note that Body Data and Parameters left empty
screenshot_3
So, please help me to figure out what is wrong in configuration to make upload successful ?
After 1 day of struggle I've found the solution and now the upload is successful.
So, using the same configs that were specified in my question
the only thing you need to add is to proceed to 'Advanced' tab of your HTTP Request and set 'Implementation' parameter to Java
https://i.stack.imgur.com/GtEDz.png
Remove Content-Type header from the HTTP Header Manager
Tick Use multipart/form-data box for the HTTP Request sampler:
Going forward be aware that you don't have to manually build file upload requests (as well as any other requests), you can record the file upload event using HTTP(S) Test Script Recorder, just make sure to copy the file to "bin" folder of your JMeter installation otherwise JMeter won't be able to properly catch the request and generate correct HTTP Request sampler, see Recording File Uploads with JMeter for more details
According to JMeter Best Practices you should always be using the latest version of JMeter so consider upgrading to JMeter 5.3 (or whatever is the latest stable version available at JMeter Downloads page) on next available opportunity
Completely new to JMeter.
Just wondering if it can be configured to generate a file (i.e. .csv) and then post said file with a HTTP POST?
I've searched a bit on the internet but can't work out whether it is possible...
Reason I want to do this is that I want to test a server that receives data in the form of a .csv file and uploads it to a database. Hoping to test this server by sending a whole bunch of randomised data.
Would be good to have different threads sending different amounts of data at different rates.
Any tips would be amazing, I am a complete newbie.
Cheers
It is possible to upload a file using JMeter HTTP Request sampler.
JMeter supports beanshell which is Java - scripting language. It can be used to create a CSV file& store it in some path.
Update the csv file path in the 'Send file with the request' of the HTTP Request sampler.
We have moved to using PLupload for file uploads and found that it can support "chunked" file uploads. The problem is that our server sees one large file upload as multiple smaller files coming in multiple POST requests.
Does anybody know if Apache Commons FileUpload supports chunked uploads?
FWIW looking at the PLupload webpage the "Chunking" they are talking about is not "HTTP Chunking". http://www.plupload.com/index.php
Their marketing term "Chunking" is their concept of sending a large payload up in small and separate HTTP requests. The server is required to have logic to group, stitch up and verify all the small parts. You are better off getting help on their forum on this. There is no reason why this logic can not be created by you on the server side and maybe they have example Java code implementing it.
Useful info and pointer to their upload.php example (maybe you convert to Java and on top of Apache Commons FileUpload) :
http://www.plupload.com/punbb/viewtopic.php?id=1484
What you are observing the small segments of a file arriving like they are separate files is exactly how the "PLupload Chunking" mechanism works. This technique is not defined in any standard, but it is also not an uncommon solution to the problems it addresses.
The "HTTP Chunking" is standard for defining how to transfer a single HTTP Request (and/or HTTP Response) between click/server using a HTTP transfer encoding. This is supported by all webservers and all browsers and has been around for a long time (since HTTP/1.1).
I am trying to load-test a web application using JMeter. I used proxy and then run the test. I am able to login into the application, but for some pages it is giving response code 4** in JMeter.
After some homework I found that the request I am sending through the browser and Jmeter might be different, so to check the same I am using fiddler. Is this the correct approach to find the root cause of the problem? What all things/attributes I should compare in fiddler and Jmeter for such requests?
Any help is appreciated. If you want, I can provide more information.
Thanks a lot :)
Abhijeet,
Edit the jmeter.properties file which is located in the bin directory.
Un-comment the proxy.content_type_include=text/html|text/plain|text/xml
Save the file and restart Jmeter.
Try recording and see if this makes a difference.
