Monitoring will be crucial to properly orchestrate next-gen services Indeed monitoring’s output can be exploited to choose where to deploy application services for the first time and to decide when and where to migrate them in case their QoS and contextual requirements cannot be satisfied by the current deployment and infrastructure state However only a few works have focused so far on the design and prototyping of monitoring tools for next-gen Cloud-IoT computing platforms In this context FogMon (https://githubcom/di-unipi-socc/FogMon) is an open-source C++ distributed monitoring service targeting heterogeneous infrastructures along the Cloud-IoT continuum eg Fog computing FogMon monitors hardware and virtualized resources at different Cloud-IoT computing nodes end-to-end network QoS between such nodes as well as available IoT devicesMore
