      Hi

      for chat application, you need to know how and which protocol the chat is using. (usually websocket), then use jmeter's samplers (use plugins) associate with your needs. (like UDP).

    Hi

    Can you provide help me providing inputs of implementing jenkins with CI - ours is not a development project

    we would like to implement jenkins and run jmeter as headless can you provide step by step configuration

      This is one of the most easy way
      > create a bat file or shell script file to run jmeter in command line (test before apply)
      > install jenkins and create new job (free style) http://screencast.com/t/9TnokZN9h
      > add the bat commands inside the job..

      Done >

      Another way -> there is a plugins called performance plugins which runs jmeter as maven job execution which shows graph. That need one time configuration only.
      [CI things I dont used to write as those are kind of easy to do, not core testing, if you have some queries, mail me, I will write some blog post for Jenkins only for that ]

    Thanks for your prompt response,

    But I am planning is to run JMeter headless and once after the test is completes I need to see the build results in HTML format or CSV ..

    Have seen the performance plugin for Jenkins for me the configaration is difficult task and I would like to accomplish the task with a few clicks and my manger needs to gain access of the results in a web portal so he no need to depend on our email

    Let me know more information, thanks for your support beforhand

    Hi

    Now that I have configured performance plugin to run JMeter headless - test ran successfully, however the build failed for below reason.

    Performance: no JMeter files matching 'D:\JENKINS\jobs\JMeter_Freestyle\workspace\results\jtl\**\*.jtl' have been found. Has the report generated?. Setting Build to FAILURE
    Build step 'Publish Performance test result report' changed build result to FAILURE
    Finished: FAILURE

    One more issue is I am not able to view the performance trend report -- I dont have clue why this is happening.

    I am able to view the .jtl and .html files in respective folders - Any inputs is much appreciated

    Thanks

      record login & logout steps in jmeter , see data coming & going, co-relate those, and run jmeter thread as your configuration. if you have 1000 users via CSV file , you can read using csv file reader. This is very simple, lots of videos in utube for this.

    Hi shantonu

    Need some clarification , An interviewer asked me question on performance testing
    1. How many threads are you running , Suppose 100 how do you justify that 100 users or requests are going parallel how do you justify 100 users are generated in your Processor parallely.

    Thanks

    1. Shantonu Sarker3:51 PM, February 12, 2016

      100 thread does not means all parallel. To ensure parallel user you need to use additional steps to make it parallel requests. when you create 100 threads, Jmeter or any other tool will try to create and run in parallel but due to resource allocation, they cant ensure.
      to ensure parallel requests you need additional technique to ensure
      1. Wait timer -> you need to wait for 100 request thread to generate and request them all together
      2. Multiple long iteration -> iterating whole execution 3-5 times , to make it possible to have all of the request generated and run in parallel

      With jmeter, I use different timers to do that.

      and the is level of concurrent/paralle users. Usually tools measures requests/user over 1 second.

    Hi, I am trying to test a web application in Jmeter. It is just simple login and logout. when i created scripts in Vugen and Jmeter. When i run a small smoke test with 5 users Jmeter RTS observed are very high compared to Vugen. almost vugen & Fiddler RTS are matching for single user but not for Jmeter. # of concurrent connections are also has a difference from Vugen to Jmeter.

    Looking for a resolution. Please suggest me. I am trying recording the script with Blazemeter extension and run that from Jmeter. not sure whether it will be helpful.

    Please help me with any other workaround.

      Jmeter script timing may differ for number of reason.
      1. As it is Java based tool, need initiation time for thread. So, some added initial time
      2. Jmeter GUI is not suitable for any decision making testing.
      3. If you add any visual listener/tree, it will slow up the whole execution. Massive sample collection make this.
      4. If you add response assertions, it will added up to response.
      I prefer , if you are comparing, run Jmeter from command line , use => Generate Summary Results listener which shows results in command line

    Hi shantanu,

    It's a great blog.

    Can you give me some idea/example of what is jmeter framework?
    Isit only generalizing the variable fields or is it is like using jmeter API with java code ..just like selenium framework.

    Thanks,

      jmeter framework => Jmeter API, you can get whole Jmeter from maven and make your own test tool or framework based on that (that we do for projects in big scale). You can customize jmeter with lighter resources to run more accurately. Usually project specific need can specify what you framework should need. As jmeter is a plug-in based architecture (micro kernel), you can make your own component and use with exist jmeter system.

      Example, let say you have chat system with your own type of protocol. So, you need to implement the protocol request and apply like as jmeter sampler. You need to make a maven/gradle project where you extend and organize whole jmeter dependency (with properties) and use your protocol request. Then the whole project will be run locally or from CI as jmeter runner. (single node, distributed or cloud)

      for WCF, you need to run your web server locally and use jmeter test via http calls (XML body)..
      if you have WSDL, you can parse and make function calls. (tested long time back in 2014)

    Hi Shantonu
    Keep up the good work. I am currently working on doing stress testing on a website that loads BI systems across various platforms.
    I have tried with multiple solutions but nothing worked. My use case is as under:
    1. Create a load of 5000 users
    2. All 5000 users log in concurrently.
    3. They all visit the dashboard that has a video playing on it.
    4. Logout of the system.

    The script works flawlessly for 4000 users but if I try putting the load of 5000 users, I start receiving the following error:


    Response message: Non HTTP response message: Connect to failed: Connection refused: connect

    When I try requesting the same endpoint to server manually, it replies back, though it gets a little slow.

    I am really not getting, why I am facing such an issue.


    Any help will be highly appreciated.

      "Non HTTP response message" => problem with load generators. either your jmeter PC is over used or out of resources.
      Increase JVM memory to see if it works.

    Hi,
    i have a question in Jmeter
    I have conncurrency Thread with set up
    Users: 100
    Ramp: 5 mins
    Step up:10
    Hold : 30 mins

    inside the Thread, i have
    1. Once Only Controller with 5 transactions
    2. Switch Controller with 5 switch case
    I have csv config to send username and pwd and actionFlag based on that the switch case transactions will work. In the csv file 100 lines with different record name and different actions to perform for each record(5 actions divided equally among 100 records)
    When i run the thread, no of transactions are more than what i expected. For example if 5 users are having create Record action, after thedefined 5 users as per the csv completes creating record other users fro mthe csv files are also doing create record rather than the same 5 user repeating the action till the hold time.
    Please clarify me how the concurrecy thread works with switch controller
