I recently faced a few tricky questions during an interview.I would really appreciate if anyone can help me with these questions.
a) How can we apply asymmetric/unequal loads to execute using different Jmeter slaves (all concurrently) through Jmeter distributed testing setup. (Example: slave 1 applies 60 thread load, slave 2 applies 150 thread load, slave 3 applies 200 thread load)
b) Also are there any means by using which we can fire loads through different slaves "sequentially" using Jmeter Master controls. (Example: slave 3 fires after slave 2 which fires load after execution of load by slave 1)
Eagerly awaiting a response!!!
a) For each of the slave nodes, you could apply different parameters to the jmeter-server startup so that
slave#1: jmeter-server -Jthreads=60
slave#2: jmeter-server -Jthreads=150
slave#3: jmeter-server -Jthreads=200
And then pick this up in the testscript and a thread group by referencing ${__P(threads)}
b) Maybe, but it seems unlikely. From what I understand, remote testing is basically the master uploading the testplan to the slaves and they run independently of each other. Cannot think of a way to script your way to a sequential execution across slaves...
