But the logs are complaining about AUTH_LOGIN not Case_Id where is AUTH_LOGIN defined and is the value getting returned as expected?
I you are indeed defining this variable as a result of a previous request, I would consider the possibility that required request is not getting a good response, or the structure has changed to the response and the JSON Extractor cannot find the value. Once again though, when is it occurring? Is it: - all slaves all the time - some slaves all the time - some slaves some of the time - all slaves some of the time? Does the issue occur from the beginning of the run or after a period of time and does the frequency of the issue increase over time? -----Original Message----- From: Anil Gaur [mailto:[email protected]] Sent: 30 August 2017 12:15 To: JMeter Users List <[email protected]> Subject: Re: Need Help I have used JSON Path extractor to catch the id and same id is passed in next request(${Casse_id}). Variable are not defined in script.Simply i am using correlation and after getting the value from Case_id=Data.ID, Assign the value to required request. ________________________________ From: Stuart Kenworthy <[email protected]> Sent: Wednesday, August 30, 2017 11:10 AM To: JMeter Users List Subject: RE: Need Help Still looks like it is not able to resolve the variable AUTH_LOGIN otherwise I would expect to see the ID being used, how is this variable set? -----Original Message----- From: Anil Gaur [mailto:[email protected]] Sent: 30 August 2017 12:07 To: JMeter Users List <[email protected]> Subject: Re: Need Help I think this is the issue.

What are your settings in the CSV data set object? Also, have you had a look at the slave jmeter logs to see if anything is complaining in there? Once again, dependant on how you start the slaves, I would expect them to be in {jmeterfolder}\bin\jmeter.log but you can stipulate this by adding: -j <absolute file path of where you want the log file> to the command line when you start the slave. -----Original Message----- From: Anil Gaur [mailto:[email protected]] Sent: 30 August 2017 11:57 To: JMeter Users List <[email protected]> Subject: Re: Need Help Master and Slave both are on Windows 2012 R4 server.

Is the problem always occurring on some slaves and not on others? Also, does run length increase the likelihood of 0 being used? Also what OS are you running your mast and slaves on? How are you choosing your data at run time? CSV... What are the settings of your CSV data set if being used? This is unlikely if you have not changed your data or script, I expect you are using a random and it decided it's had enough of the randomness. Random... Could you be using anything that generates a random? Daft as it sounds, I had problems with jmeter and random, well actually the java object it uses to create a random, in distributed mode and had to find other ways around it. If so how are you using it? There is a bug in some versions of java that causes entropy in random and it eventually returns 0 always. Jmeter has even changed the way random is created in some controllers dependant on which version you are running. Problems with random can be caused by resource contention dependant on the implementation, for example on lunix where /dev/random is being read by multiple threads and either no being available or the result not having any readable characters. I cannot remember it very well and I am no longer working on that project, but I think what I did was in each thread create a random 256byte readable string then cut it up each time it was read. This meant random was being read a lot less and threads would wait until all 256 bytes were available before trying to use it, had little impact on run speed. As with you, things went very well for a while then stopped working. It was some time ago so may need to play around with my solution. Here is my groups discussion when it happened. https://groups.google.com/forum/#!topic/ptgram24/tOXD2pCu9vQ Thanks -----Original Message----- From: Anil Gaur [mailto:[email protected]] Sent: 30 August 2017 11:14 To: JMeter Users List <[email protected]> Subject: Re: Need Help Yes, Nothing has been changed.

In distributed load, only the script file itself is sent, any fragments, external scripts, data, anything not in the original jmx must also be in the same place on the slave. This allows for host specific data, external tools and such to be used. If using relative file paths, it starts from where the slave service is executed which should be the jmeter bin directory, but could be different dependant on how you start jmeter.

While Executing only Master System I have created and validated the script and found that all entries are inserted in DB properly using the script. But this is only working while I am validating my script on master system. I have executed the same script with 50 users on master system and found all the data inserted properly in DB. While Executing with Master-Slave(Distributed Testing) While doing the execution with master and slave then "0" values are inserted on Patient and Case id. Rest all the data inserted properly. For the same issue i have verified the request and found that in request its taking "0" values from the correlation.But while same script is running with Master only then all data is inserted properly.
