  In this paper we present a comparative study between PYTHIA, EPOS, QGSJET,
and SIBYLL generators. The global event observables considered are the charged
energy flow, charged-particle distributions, charged-hadron production ratios
and $V^{0}$ ratios. The study is performed in the LHCb and TOTEM fiducial
phase-spaces on minimum bias simulated data samples for \emph{pp} collisions at
$\sqrt{s} = 7$ TeV using reference measurements from the aforementioned
experiments. In the majority of cases, the measurements are within a band
defined by the most extreme predictions. The observed differences between the
predictions and the measurements seem to be, in most part, caused by
extrapolation from the central pseudorapidity region ($|\eta| \leq$ 2.5), in
which the generators were mainly tuned.
