Vuser distribution along generators

Question

I have 6 VUsers on 2 Load generators. With Percentage scenario mode Controller distributes them like this:

VUser ID | Load Generator
---------|---------------
1        |  vm-1
2        |  vm-1
3        |  vm-1
4        |  vm-2
5        |  vm-2
6        |  vm-2

I would like distribution with alternating (repeating sequence) Load Generators like this:

VUser ID | Load Generator
---------|---------------
1        |  vm-1
2        |  vm-2
3        |  vm-1
4        |  vm-2
5        |  vm-1
6        |  vm-2

How can I achieve this? Changing to Group mode gives me option to specify generator manually, but this is inconvenient and error prone.

Answer 1

Create two groups of three apiece and ramp them up at the same time. Assign each group to a distinct generator

Answer 2

I had to do similar thing for 1500+ VU and what worked best for me was to copy all the generators (distinct one's) in order in one script by double clicking on it in Run tab. So let's say you have 10 so copy 10 rows in "Load Generators" column after assigning each row with unique generators. For me there were 9

'loadgen00'
'loadgen01'
'loadgen02'
.
.
.
.
.
'loadgen08'.

Once you have done this, you can then start pasting it for below series and it will take generators in same order. You will get a message "The dimensions of the data on the clipboard is larger than the selected region. Truncate clipboard data?", just click NO. Not sure if this helps but earlier I was changing for each of the 1500+ VU's manually and it was painful and time taking. By this I save lot of time.
