Want to know how this plugin works..

[arbazalam2z]

Hi Hemikak,

I have a scenario in which i have suppose to send 20 messages and after each message sent connection should be disconnect and again connect to send next message. Does this plugin serve my purpose. I also would like to know how this code works.

Thanks Arbaz

Hi @arbazalam2z , Sorry this does not support requirement. The same issue is there with JMS sampler as I know.

But you can use the following options below. You will have to create 20 thread groups. Each thread will send 1 message. The threads will be consecutively executed once you have done the change to the "TestPlan"

Actually i have to deal with 50K message per minute, in that case threading concept of JMETER will not work. What if i can introduce diconnect() function in the code?

Is this only for publisher side? or are looking for subscriber side as well ?

[arbazalam2z]

Thanks for quick reply.. :+1:

Yes it is for publisher side only.

Hi @arbazalam2z ,

Try out the attached diff. Only tested it a bit. You will have to changed the extension to 'diff' from 'txt'.

Please close this issue if the above patch resolves the issue. Please note that I wont be merging the patch at the moment.

[hemikak]

@arbazalam2z was it that the patch could not be properly patched ?

The implementation was that for each sample a client gets created , published and then destroyed.

is your requirement to use the same client to connect, publish and disconnect ?

[arbazalam2z]

@hemikak As per my requirement it is not necessary that client should be same, it may be different either. I have patched it properly. If possible please upload complete zip or email me at: handsomearbaz@gmail.com

Thanks, your help is really appreciated... :+1:
