JMeter Distributed Load test Query

Nayak, Soumya R.
Hi All,

In JMeter Distributed Load test --> It multiplies the load as per the no of slaves. The same test plan is run by all the servers. JMeter does not distribute the load between servers, each runs the full test plan. So if we set 100 Threads and have 6 JMeter server, we end up injecting 600 Threads.

But my requirement is --> Let's say there are 80 Threads or 80 Virtual users and I have 4 slave machines and I want to distribute the load like
Slave 1 - 15 Virtual users/threads
Slave 2 - 25 Virtual users/Threads
Slave 3 - 10 Virtual Users/Threads
Slave 4 - 30 Virtual Users/Threads.

So how to get it done and let's say I have 200 test cases in a table in Database and when I run the test from the Master machine it should start the test with the 4 slave machines and the 200 test cases should be uniquely distributed across the 80 Virtual users/threads in the 4 slave machines.
How can I achieve the above scenario? Please help.

More ever how can I monitor from the master machine the issues if any occurs with any of the slave machine?

Regards,
Soumya

Re: JMeter Distributed Load test Query

 1. You can choose how many threads will be started for this or that slave
machine by setting the number of threads in  Thread Group
<http://jmeter.apache.org/usermanual/component_reference.html#Thread_Group>
(s) using  __P() function
<https://jmeter.apache.org/usermanual/functions.html#__P>   like


> ${__P(threads)}

 

Once done you can define the desired number of threads on each slave in
/user.properties/ file , i.e. on 1st slave:


> threads=15

on 2nd slave


> threads=25

2. You can switch code execution lines depending on slave machine using  If
Controller
<http://jmeter.apache.org/usermanual/component_reference.html#If_Controller>  
and  __machineName()
<https://jmeter.apache.org/usermanual/functions.html#__machineName>   or
__machineIP()
<https://jmeter.apache.org/usermanual/functions.html#__machineIP>  
functions combination like:


>  - If Controller, condition: "${__machineIP()}" == "10.10.10.11"
>    - requests for slave with IP address 10.10.10.11

3. You can set *mode=Standard* property for all slaves, this way they will
send full results to master as soon as they will be generated. This way you
will be able to "normally" analyse the .JTL results file in the realtime.
See  Using a different sample sender
<http://jmeter.apache.org/usermanual/remote-test.html#sendermode>   for more
details.

RE: JMeter Distributed Load test Query

Nayak, Soumya R.
Hi,

I tried with the below configurations putting IF condition for each slave machine, in that if condition I have declared User defined variables,
But what is happening its picking up the last IF condition parameters irrespective of machine IP and machine name.
So please let me know how to handle the condition ??

Regards,
Soumya

Also ,

I am not getting the response data from slave machines to the master.
I had put mode= Standard in user.properties in all slave machines but still not returning.

Re: JMeter Distributed Load test Query

shettyd
Hi
a. Please use separate threads for separate issues - it is difficult to
follow
b. Please check JMeter logs for errors when things do not work
c. Please provide more useful descriptions of what you did , what did or
did not work etc. e.g. I put multiple IF controllers , it did not work is
not useful.


In your case
a. First get a basic script to work with master - slave (hence eliminate
any connectivity , setup errors) -
https://jmeter.apache.org/usermanual/jmeter_distributed_testing_step_by_step.pdf
b. Then get the threads suggestion working if you want to vary load -
However consider  why you want different slaves to generate different loads
c. Then add more complex steps into your script and resolve each issue as
it arises.
As before use a separate topic for each distinct issue that you may run into

regards
deepak

RE: JMeter Distributed Load test Query

Nayak, Soumya R.
Hi ,

I had put multiple IF controllers in Script like currently I had two IF controllers ---
First IF controller --> Condition - "${__machineIP()}" == "172.16.60.44"
Second IF Controller --> Condition - "${__machineIP()}" == "172.16.60.188"

In the above two IF conditions I have parameters like no of threads , no of input records to process with respect to the specific slave machine.
So when I ran the test with two slave machines with the mentioned IP addresses above. Each slave machine should have picked up their parameters based on the ip address condition but what was happening was that instead both the machines picked up values/parameters from the last IF condition.

So what I could find was the IF condition were not validating.
Am I doing any error or some other way of handling the particular slave machine.

Regards,
SOumya
