How to identify the individuals not satisfying non-linear inequality constraints?

I am using Genetic Algorithm to solve a problem which involves minimising a fitness function, subject to some non-linear inequality constraints and decision variables subject to integer constraint. I am setting Penalty as a non-linear constraint algorithm which adds a penalty to the fitness value of infeasible individual (not satisfying the constraint) depending on the constraint violation and worst feasible fitness value in that population.
I am also saving GA population history and scores during all generations. Now, I want to visualise that during each generation which individuals didn't satisfy the constraint and caused a penalty in fitness value?
I want to show whole optimisation process like individuals during 1st generation (feasible and infeasible), with corresponding fitness value and evolving to the optimum solution till last generation

If you know what are the constraints, make a constraint function, then input the individuals to get the constraint output (for knowing the infeasibility). Do you know the constraints?
