hi group
I’m new in RubyonRails world i need to define a method that will

as in something that will create that amount of load on the computer
it’s running on ?

no just by fake numbers that will be generated from the method inside
the model

Two options:
1+rand(100) will give you a range of 1-100 (it will never show as 0%)
rand(101) will give you a range of 0-100 (0% is possible)

Basic ruby 101 to be honest.

I don’t know what your actually trying to accomplish, but it doesn’t
seem to me that simply generating random numbers between 0 and 100 would
be a very realistic test of CPU load. Load on a CPU wouldn’t look like
random noise.

I think I would generate random numbers that add to another value in
small increments in some form of moving average to produce a more
realistic result. But, this depends on if you care about the value over
time, or just need an instance in time value.
