How have each thread use a unique User-Id
I've been wondering about something like this.
I feel like there needs to be a Interleave Controller that works within the
Thread group rather than just within a Loop.
An example of why this is necessary:
I would like Thread 1 to login as User 1, thread 2 to login as user2 etc.
This is what I thought the Interleave controller did but it doesn't; Thread
one log's in as User one, thread2 logs in as User 1, etc.
The reason I need this is that our App stores individual user info in a
Session that gets changed as they progress through our website. If 2 threads
are using the same User-id they will be affecting each other's Session
values with unpredictable results. I want each thread to use a distinct user
id.
I want the several threads to be hitting the server at the same time but as
distinct users. The only way I can see of doing this now is writing several
almost identical scripts except for the login and running them
simultaneously as several jMeter runs.
I believe I saw this come up before and I'm sorry if I'm asking a question
that has already been hashed over but I am unable to view my jMeter mail
archive today. If there is an answer already can someone forward it to me?
Thanks in advance
Andy

Subject: Random Controller question
Hello All:
Does anybody know if Random Controller works the way it was supposed to
work
according to the documentation?
I was trying to achive this using Random Controller, but looks like it
refuses to work. I have installed 19th Nightly build but the problem
still
persists.
Thread Group
- HTTP Requests defaults (A)
- HTTP Cookie Manager
- Only Once Controller (B)
- HTTP request to login
- Loop Controller (C)
- Random Controller (D)
- Simple Controller (E)
- HTTP Request 1
- HTTP Request 2
- HTTP Request 3
- HTTP Request 4
- HTTP Request 5
- Simple Controller (F)
- HTTP Request 1
- HTTP Request 2
- HTTP Request 3
- HTTP Request 4
- HTTP Request 5
The problem which I'm facing here was that JMeter stops executing
whatever
requests under Label (E) & (F) after initially executing two or three
requests under both of each controllers. What I expected was that JMeter
would excute all the requests under Label (E) or (F) randomly. Is't it
the
way Random Controller supposed work? Or I'm I doing something wrong?
To zero it on Random Controller for the fault, I also moved (E) & (F)
controller directly under Loop Controller. Everything worked fine then.

Rohit Peyyeti

You can do this with the new User Parameters config element. It's available in the
nightlies. It lets you specify thread-specific values and use them as user-defined
values.
Documentation about user-defined values is availabe at:
http://jakarta.apache.org/jmeter/usermanual/functions.html
and from there, the User Parameters config element should be fairly self-
explanatory from the GUI.

RE: How have each thread use a unique User-Id
Posted by Wangke Liao <wa...@yahoo-inc.com>.
You don't have to go that way. Here is a very simple way to simulate x users
using x threads independently, hint: use Parameter Mask:
--thread group (X threads)
-- HTTP Req default
-- HTML Parameter mask (loginID = userx where x from 1 to X, step 1, use
the settings inside. Do the same trick for pwd, or for simplicity, just use
the same pwd)
-- HTML Cookie manager, if needed.
-- Once only Controller
--login (in login page, set loginID value to "*", without the quote - this
will tell JMeter to use the values generated sequentially in the Parameter
mask.)
-- loop controller
-- other user actions ....
-- logout
You can define how many loop you need either from "loop controller" or
thread group, or even both. Either way, each time of the loop X threads will
pick, no more no less, X unique users.
