  The main aims of the NA61/SHINE experiment are to discover the critical point
of strongly interacting matter and to study properties of the onset of
deconfinement. For this goal a two dimensional scan of the phase diagram
(T-$\mu_{B}$) is being performed at the SPS with measurements of hadron
production in proton-proton, proton-nucleus and nucleus-nucleus interactions as
a function of collision energy and system size. It is expected that
fluctuations of various dynamical quantities will increase close to the
critical point. In this contribution recent results of measurements of
fluctuations in p+p and Be+Be collisions at SPS energies are presented as well
as comparisons with model predictions and corresponding data of other
experiments are discussed.
