Abstract: Resource capacity and load monitoring is a basic research topic in cloud computing platform.In this paper，an adaptive resource and load monitoring method are proposed to be used in heterogeneous computing environment.According to system operating environment and the changes of resource workload，the method combines periodic pull mode with event-driven push mode to adaptively publish and retrieve system load and resource information.Preliminary experiments reveal that，by using adaptive monitoring method，the efficiency of system monitoring is improved over that accrued by using regular monitoring approach.
