Seshat: uma arquitetura de monitoração escalável para ambientes em nuvem
System monitoring has an essential role in management, maintenance and to provide feedback through data collection. Particularly, cloud monitoring must address several virtualized resources of dynamic behavior, such as infrastructure performance metrics, application logs, and data produced in distributed environments. This paper presents a layered cloud monitoring architecture which is scalable, elastic, responsive and extensible. Such architecture has been tested through an implementation based on open-source tools to monitor a massive data processing environment in which its scalability has been confirmed.
