摘要：The use of distributed systems has become increasingly diffused and accessible, especially cloud computing, which is used to deliver computational services to small, medium, and large enterprises. Building and maintaining a private cloud infrastructure may not be trivial, due to requirements of being accessible from anywhere and at any time. Therefore, monitoring and management activities are essential to identify and mitigate failures that may occur, and thus keeping service availability. Several studies show that some failures are caused by a phenomenon called software aging, which refers to the system's degradation during its operational life. This paper describes the design and implementation of the DR Monitor, an integrated platform to monitor and mitigate software aging effects in private cloud computing infrastructures. Several test scenarios demonstrate the operation and effectiveness of this tool, which empowers the proactive management of distributed computing resources.
