OCCI Monitoring
Augusto CiuffolettiMotivation
I SLA is a defined target to obtain user confidence
I SLA is tightly related with monitoring, so we start fromcloud monitoring
I The user may be in its turn a service provider (insidemonitoring)
I The user may simply want to verify the quality of theservice (outside monitoring)
I In both cases, the user needs the tools to defineresource monitoring
I Keep into account the case of a composite service(many providers)
I A simple API aligned with OCCI

I Distiguished activities that need the provision ofcomputing, storage, networking resources
