Description
An overview of ALICE results on the charged--particle pseudorapidity density measured over a broad range ($|\eta|<5.0$)
in \mbox{p--Pb} collisions at ${\sqrt{s_{\rm NN}}}=$5.02 TeV and \mbox{Pb--Pb} collisions
at ${\sqrt{s_{\rm NN}}}=$2.76 TeV is presented.
This includes extension of the previous measurements reported by ALICE into more peripheral collisions
and with higher granularity for \mbox{Pb--Pb} and a broader $\eta$ range in \mbox{p--Pb}.
The measurements in the forward regions are performed using the Forward Multiplicity Detector (FMD).
The FMD signal is dominated by secondary particles produced in surrounding material necessitating the use of a data--driven approach
to extract the primary charged-particle density.
The results are compared to predictions from various models.
