  We present MoonLight, a tool for monitoring temporal and spatio-temporal
properties of mobile and spatially distributed cyber-physical systems (CPS). In
the proposed framework, space is represented as a weighted graph, describing
the topological configurations in which the single CPS entities (nodes of the
graph) are arranged. Both nodes and edges have attributes modelling physical
and logical quantities that can change in time. MoonLight is implemented in
Java and supports the monitoring of Spatio-Temporal Reach and Escape Logic
(STREL). MoonLight can be used as a standalone command line tool, as a Java
API, or via Matlab interface. We provide here some examples using the Matlab
interface and we evaluate the tool performance also by comparing with other
tools specialized in monitoring only temporal properties.
