Hi,

Use counter and increment the variable.

Hi Prakash ,

Using getThreadNum , I could get the thread number. I am running my threads
in loop. Is there a way I can get the loop number also ?
Thanks.

multiple threads on different machines ?
You can distribute JMeter so that it runs on different machines - but you
really dont want each jmeter machine to only run one thread.
Its easier to run your request through a tunnel or proxy , see what the
command line is really sending to your server and then simulate that in
JMeter (there may be something like custom authentication schemes or binary
stuff that might prevent this approach)

Re: How can I make different threads use different values?

[Sheetal Jharia Baru]

Deepak ,
You have a valid point. Running multiple OS processes may not simulate it
accurately. In ideal case, we will have different users running the
same *command
line *requesting images from our single server (this server is load
balanced obviously).
I believe JMeter has feature to simulate such scenario by invoking multiple
threads on different machines ?

Re: How can I make different threads use different values?

Hi Deepak, Prakash,

Thanks a lot for your help. Both CSV Data Set config and ctx.getThreadNum
solved my problem. I am new to JMeter and finding this small piece of info
in vast documentation was difficult.

Thanks!

Re: How can I make different threads use different values?

[Prakash Palnati]

You can use ctx.getThreadNum which will return the current thread number
and use that variable to differentiate which image to point/download.

And when real users are uploading/downloading images , they will all do so
from the same physical server - if not then you might not be able to
simulate this accurately - as running multiple OS processes on the same
server can be quite different than running the same process on different
servers (HTTP fares better in that respect)

Re: How can I make different threads use different values?

Thanks for the links, I will go through them.
Even though it is http protocol , I have to use product specific commands
to download and upload the image to the URL.

Re: How can I make different threads use different values?

[Deepak Shetty]

hi
yes this is pretty much standard for Jmeter. You can use variables
${variableName} and you only need to setup how this variable gets
populated. The most common element used is CSV data set config - but there
are others too (read the component reference)

See -
http://jmeter.apache.org/usermanual/component_reference.html#CSV_Data_Set_Config
And you can google for tutorials
https://www.google.com/search?q=CSV+data+set+config+jmeter+tutorial=utf-8=utf-8


Im curious why you are using an OS Sampler for the purpose of downloading
an image ? is the protocol not HTTP ?

How can I make different threads use different values?

[Sheetal Jharia Baru]

I am using OS Sampler to execute a shell script on my local ubuntu system.
This script in turn downloads a image from remote repository. As expected ,
when the script is run multiple times, same image is downloaded. Is there a
way that each thread can download a different image (can image become some
sort of variable and I can give different image name via this variable to
each thread ?
Any help is appreciated.
Thanks !
