摘要

PROBLEM TO BE SOLVED: To integrally monitor operational states of virtual machines and applications running in the virtual in an environment.SOLUTION: An orchestration device 4 controls a virtual machine or an application 5 and a monitoring device 3 monitors an operational state of the virtual machine or the application. The orchestration function updates environment information 90 which is information on the virtual machine or the application. The monitoring function acquires access information identifying a virtual machine or application of monitoring object S502, S505 on the basis of the environment information updated by the orchestration function, transmits a monitoring message to inquire about the operational state of the monitoring object on the basis of the acquired access information to the monitoring object S507. When receiving a reply message which is a reply to the monitoring message S509, the monitoring function determines the operational state of the monitoring object S511 and outputs the determination result to a prescribed output destination S512.SELECTED DRAWING: Figure 5
