Monte Carlo event generators used at LHC are inspired by QCD and rely on phenomenological models where perturbative QCD cannot be used, e.g. for the description of the underlying event and hadronisation. This requires experimental data to constrain and tune the models, and to ultimately gain insights in the underlying physics.

A Large Ion Collider Experiment (ALICE) at the LHC provides tracking down to low transverse momenta and excellent particle identification. This allows us to perform measurements which are well-suited to constrain the existing Monte Carlo models in the non-perturbative regions of QCD. Our measurements extend over different collision systems (pp, p-Pb, Pb-Pb) and different collision energies. We will discuss the relevance of these measurements for Monte Carlo comparison and tuning, foremost for pp collisions. In addition, we will outline ideas to extend the systematic Monte Carlo comparisons to heavy-ion analyses.
