An overlay resource monitor system


This study proposes an overlay resource monitor system which is highly scalable, extendable and self-configurable called ORMAN. The monitor system is build upon a cluster-based topology P2P system and consisted of a monitor agent. The monitor agent contains a set of sensors, called information collection modules (ICMs). ICMs collect the states of monitored attributes, record the attributes and compute the statistic values of monitored attributes in each node. ORMAN provides several resource management mechanisms, such as event notification, admission control, fault tolerance and load balance. ORMAN also provides a set of APIs for developers to design customized ICMs and plug them into system on the fly
