Jmeter 2.12.
I used a scenario fully functional in front of a reverse proxy Apache. Recently we 've replaced the reverse proxy with the F5 BIGIP technology and now my scenario hangs.
The problem is for a particular ajax POST request the HTTP response is truncated : i receive a 200 OK but the HTML content is not full (no html tags for example). When i post the same request with Firefox the full content is ok.
Note that i don't receive the http header Transfer-Encoding: chunked.
In this case what can be the difference between Firefox and JMETER ?
Anyone have an idea on how could i get the full html response ?
Thanks for any reply.
That completely depends on the settings on your F5 and what exactly you mean with "response is truncated" and "no html tags". Do you get the correct response but the html tags are stripped out? or is the response just truncated so you i.e. only get the first n bytes?
The best way to find out what is actually going wrong is to use something like fiddler in between and try to find the real difference between the responses, especially regarding the response headers (Content-Length, Transfer-Encoding, etc).
When you found the actual difference please post here so we can help you further.
On a sidenote, by any chance do you have some custom coding on the f5 (iRules) which react to different user-agent settings?
Given you send identical requests you should be receiving identical responses.
Use JMeter's View Results Tree listener to inspect request details, or even better compare requests which are being sent by Firefox and JMeter using a lower level network sniffer tool like Wireshark, detect the differences and configure JMeter accordingly to send the same request(s) as Firefox does.
The other reason might be JMeter truncating large response, by default JMeter displays "only" first 10 megabytes in the View Results Tree listener, if this is the case - you can add the next line to user.properties file:
view.results.tree.max_size=0
and restart JMeter to pick the property up - it will suppress response truncation and you will be able to view the full response data.
Alternative way of setting the property is passing it via -J command line argument like:
jmeter -Jview.results.tree.max_size=0 ....

I tried to run a POST method for API testing in JMeter, I have sent the parameters as needed in body using a csv file. It works with https url(domain url) but not working in localhost. In localhost, requested body is showing blank. Please help me to resolve this issue.
There should be no any difference between local and non-local URLs so most probably you made a configuration mistake somewhere. We cannot state where exactly without seeing the test plan so I would suggest:
Inspect request and response details using View Results Tree listener
Ensure that the variables originating from the CSV Data Set Config really exist and have their respective values by adding a Debug Sampler and seeing what variables are there.
Check jmeter.log file for any suspicious entries. If it doesn't say anything meaningful you can try increasing logging verbosity to DEBUG level.
I want to send HTTP request to a particular URL in JMeter to do performance testing, but the URL is containing a environment name in its prefix ex: http://dev-www.abc.com/. while I'm running the particular script its failing because of the URL prefix.
How to achieve this?
If you are enter server name / IP as per screenshot below then it is wrong
Protocol and server name have to be given separately as below
If you already have setup URL like the screenshot above, please update the question with screenshot of failure message
Your question is not very clear, going forward consider adding:
output of the View Results Tree listener showing request and response tab, preferably both data and headers
jmeter.log file, preferably full, or at least any messages of WARN and above severity
A couple of "blind shot" answers:
If you're asking for a single configuration point which will be applied to all HTTP Request samplers - it's HTTP Request Defaults
If you're building your request URL dynamically and getting Illegal character found in host: '/' error - make sure to put the URL into "Path" field of the HTTP Request sampler:
I am new into Jmeter and trying to do my first load test, When I get my data from website it is always come in .txt form and when this data I try to run my test it fails,
It's hard to say what is wrong without seeing the "Sampler result" tab screenshot for at least one failed sampler.
Going forward consider providing as much information as you can, i.e.:
Screenshot of the HTTP Request sampler
Screenshot of the View Results Tree listener demonstrating Sampler result, request data and headers and response data
At least relevant parts of the jmeter.log file, better with the debug logging for the test elements involved enabled
I have a scenario wherein i have to export the values(the details of a group of people) from a webpage either in CVS or PDF format in my desktop. The response was success When i recorded this scenario in jmeter. When i added recorded samplers in the thread group and ran them, i received success response with 302 response code. But the sample time is very less when compared with F12 time(manually captured it using F12 developer tool).
It was a POST request when i recorded it. In the results it was showing 3 different child samples out of that 1 is POST and the remaining 2 are GET requests. And 1 additional request with blank request.
The below is the structure:
1 /WebPages/Common/abc.aspx?mhsghgsjfgjsdg
-child1 (POST request)
-child2(GET request)
-child3(GET request)
1 /WebPages/Common/abc.aspx?mhsghgsjfgjsdg (blank request)
It's a C# application. Even for some other requests i am getting 302 response code with correct sample time. So i have no issues with those samples.
Could someone assist me to find out what could be the issue for the incorrect sample time? and how can i resolve it to get the correct sample time?
Appreciate your inputs or resolution.
Most probably you are not handling so called "embedded resources". Almost each HTML page contains some images, styles, scripts, fonts, etc.
In the "Advanced" tab of the HTTP Request Defaults configuration element tick:
Retrieve All Embedded Resources
Parallel Downloads
This way you will "tell" all JMeter HTTP Request samplers to download images, scripts, styles, etc. like browsers do therefore you should start getting comparable response time.
For more information on tuning JMeter so your test would be more realistic check out How to make JMeter behave more like a real browser guide.
Facing the issue while developing the performance script for salesforce application. The issue is, one of the apexremote post call is too large in size. Jmeter is getting hanged if i am trying to click that particular request. Even if I manage to enhance the post request somehow the cursor is not going to end of the line. Hence at the end of the line there is one CSRF which I am not able to correlate. This is only happening for only one apex post request. Because of this my orders are getting rejected while provisioning. I tried by increasing my heapsize in jmeter.bat file but no help.Searched in google but didn't find related queries. I tried the same thing with neoload and I was successfully access and enhanced that particular request.
Has anyone experienced ever! How to resolve this.
Please HELP!
1.Basically for that you need to be Patience after clicking on the request and when the request populate properly copy that post data into notepad++for correlation purpose.
2.Or other solution is Open the .JMX directly into notepad and from there copy the post data into other notepad++ instance and form there with some manipulation you can do correlation.
3.Hope you already changed the property "view.results.tree.max_size=0" in "jmeter.properties" file because may be for next correlation you will get the message like "Response data is to Large".
I had also faced the same issue several times in past, so in that case just copy the complete post body and paste it into notepad++ and modify the content there instead of modifying in jmeter itself, then paste the content back to jmeter and execute it.
This will resolve your issue but have patience while clicking on http request to copy the post body because it'll take some time to open the request properly
I have found out the solution for the very big request for which meter is getting hanged. The best solution is to take the request from the html body of the view result tree listener for the recorded original one and paste in the payload of a new sampler. Then add it in appropriate place accordingly. We can also keep a raw request and make the correlation changes there itself instead of messing around in the big request payload.
