(Virtual conference).The fifth generation (5G) of mobile networks will have to accommodate different types of use cases, each of them with different and stringent requirements and key performance indicators (KPIs). To support this, apart from novel technologies such as network slicing or artificial intelligence, 5G will require a flexible and efficient monitoring system. The collected metrics serve to optimize the performance of the network, and to confirm the achievement of the KPIs. Furthermore, in the envisioned multi-site, multi-stakeholder scenarios, having a common monitoring system is even more critical for an efficient optimization and service provisioning. In this paper, we present a Monitoring architecture for the distribution and consumption of metrics and KPIs for 5G multi-site platforms, where different verticals from different stakeholders are implemented over a shared infrastructure. We also assess the performance of the implemented publish-subscribe paradigm, to confirm that it suits the requirements of these scenarios, and discuss how the architecture could be mapped to other 5G scenarios.4eng©2020 IEEE.MonitoringData collection5g experimental validation5g trials5g multi-site platformPublish-subscribe paradigmconference paperTelecomunicacionesopen access52562020 European Conference on Networks and Communications (EuCNC2020)CC/0000031236
