eXtreme monitoring: CERN video conference system and audio-visual IoT device infrastructure

Two different use cases for monitoring are analysed in this paper: the CERN video conference system – a complex ecosystem, which is being used by most HEP institutes, together with Swiss Universities through SWITCH; and the CERN Audio-Visual and Conferencing (AVC) environment – a vast Internet of Things (IoT), which includes a great variety of devices accessible via IP. Despite the differences between both use cases, a common set of techniques underpinned by IT services is discussed in order to tackle each situation.
