I have an asp.net project ,which I want to load test with around 100 users at a time , can someone plz tell me how can I do this. I tried jMeter but it seems very difficult to understand as because I m doing this first time..Thanks In Advance
First of all, you need to create test script. You can do this manually in Jmeter GUI, or you can use Recording controller or something like SmartMeter's Recorder
After that, you should have recorded script and you can edit it. Add some neede correlations, special variables, prepared data and so.
Before running the test, change number of threads to 100, setup rump-up time and you can start your test.
I suggest you to try some tutorials about load testing and Jmeter, eg.
Tutorials point
SmartMeter's quickguide
Blazemeter's tutorial

I am new to using JMeter and have developed a basic test plan with HTTP Sampler and a few listeners. Please run me through the entire process of how I can start after opening JMeter ?
There's no right answer for this, it depends what you're wanting to achieve. I'd suggest starting with the best practices: http://jmeter.apache.org/usermanual/best-practices.html
And also look at building a web test plan: http://jmeter.apache.org/usermanual/build-web-test-plan.html
I would look at the Graphs Generator listener - https://jmeter-plugins.org/wiki/GraphsGeneratorListener/ - use these graphs to make sure you're making the number of transactions that you would expect in your tests.
Basically - the documentation is your friend. I took time to read what each controller, listener and sampler was doing and decided how to implement these myself. There was some trial and error. JMeter is an easy tool to pick up and use but there's a LOT of depth to it.
In addition to Ali1874 answer, I would suggest looking into how to run JMeter tests using command line. You can find more information at http://jmeter.apache.org/usermanual/get-started.html#non_gui. With regards to reporting JMeter is able to produce nice HTML reports when using -e -o options http://jmeter.apache.org/usermanual/generating-dashboard.html#report_after_load_test.
Also, with regards to Jmeter test plans, in my previous company we used to parameterize number of threads required, servers and other elements. In general structure looked like the one at the example test plan.
We had different user defined variables elements for different environments for faster test tuning. Also, we used bzm – Weighted switch controller (https://github.com/Blazemeter/jmeter-bzm-plugins) to distribute load among endpoints by including HTTP requests from Test Fragment element so that we would not have to duplicate requests allowing to manage them more easily. You can check out full plan at here (https://github.com/gretard/testing/blob/master/00-jmeter/results/samplePlan.jmx). Please bear in mind that test plan uses bzm – Weighted switch controller plugin and jpgc - Standard Set plugin which you can install by using Plugins manager (https://jmeter-plugins.org/wiki/PluginsManager/).
Hope this will help.
I am working for a startup. We need to Load test 500 requests for sec and 10,000 concurrent users at any given time.
We cannot afford loadrunner or any of these fancy softwares. We tried to implement it Jmeter. But it is unable to process this load.
Is there any cheaper software / online website, which can help with all the correlation issues and run the above load?
You can try our new service http://loadme.socialtalents.com
In case it is close to your needs but you need more threads please let me know
SmartMeter supports automatic correlations in the Light (free) version. It is based on JMeter, so in order to achive the desired load, follow #UBIK LOAD PACK tips.
JMeter can support this load without any issue, ensure you follow best-practices:

I am new to Jmeter and trying to understand what all can be achieved using Jmeter. I want to perform endurance or soak testing of a application using Jmeter, i.e. I want to run a particular script for a particluar number of users for a period of 3 hours.
What all options are available to me and what is the best availablelistener to monitor the result?
Please help. Kindly add if I am missing anything that I should know before starting with soak testing?
For setting up the numbers of users and runtime of the test you use a Thread Group. Setting the runtime is done by checking the Scheduler check-box and specifying Duration.
Of the original listeners in JMeter I have found myself most oftenly just using the plain Summary Report. But JMeter Plugins gives additional listeners which may be better, it depends on what you want to measure. The JMeter Plugins also gives additional thread groups, where you can specify e.g. an increasing load over time.
Use a Thread Group to set up your number of users and the duration of your test (using the scheduler of the Thread Group).
Then add all the samplers and logic controllers you need to perform your testing.
Next, add a Summary Report listener to get an overview of your results (min/max/average and such), and add a View Result Tree listener to get an overview of EACH step your testplan is taking. This Tree listener is great to actually see what jmeter is doing, and to debug your tesplan.
BTW: if you add a HTTP Request Defaults object, you can set your URL and options in there, and don't need to add it to each and every sampler again. Especially works like a charm if you start using regexp extractors and such.
I want to run a Load test on my Production server to verify that the server can handle 1 million requests per 10 seconds using JMeter. How to configure JMeter Thread group for 1 million request in 10 seconds? How many client I need to do this test?
Please share your valuable experience if you have experience doing this type of load test.
First, you should ensure you really need 1 million requests in 10 seconds (what kind of site are you testing ?).
Then if you want to use JMeter, ensure:
You use last version
You tune memory correctly
You will certainly have to use distributed testing if not using Cloud
Follow best practices
http://www.dzone.com/links/r/see_how_to_make_jmeter_run_thousands_of_threads_w.html (Disclaimer : I'm the writer of this)
http://jmeter.apache.org/usermanual/best-practices.html
You might try Constant Throughput Timer to make a kind of Barrier
Alternatively you can try "Delay thread until creation"
And finally try a Cloud solution to get to this load, see this french blog on all kind of issues you will face in all fields (not only load software):
http://blog.milamberspace.net/index.php/2012/07/14/rapport-de-tres-gros-test-de-charge-avec-la-solution-blazemeter-1161.html)
But I never tried up to this load, so I cannot tell if it will work and it is kind of unexplored field
you can accomplish this using Gatling and scaling out to several machines that would run the test in parallel. in the end Gatling can aggregate the results into 1 report.
Gatling documentation dosent provide much info for this :
http://gatling.io/docs/1.5.6/user_documentation/cookbooks/scaling_out.html
but you can check my blog post to see how this can be done (ive wrote a script for this purpose)
Blog - http://www.nimrodstech.com/gatling-cluster-load-testing/
Gist - https://gist.github.com/Nimrod007/5cfed34eeffedfd7ec76
Looks like you'd better look onto another, more suitable tool for such kind of scenario,
e.g. Tsung
Tsung homepage
Tsung # github
Scaling to 30K: Tsung
or at least Gatling instead:
Gatling homepage
Gatling: scaling out
Perhaps if you would like to use jmeter in any case you can look onto BlazeMeterLoad Testing Cloud solution.
I just learned how to use J-Meter and i am loving work with it.
I have to do load testing for a moodle install .
I wonder if there are any set of jmeter scripts to test moodle that i can re-use or like some kind of benchmark scripts that are somehow advanced and that can help me test the moodle performance.
Thanks in advance for any suggestions and links .
J Meter script can not be reused as it requires 1 time recording option.Hence you need to record your script at least 1, then keep running the script with load increase gradually depending on your server capacity.
