Disclosed is a method and program for monitoring an ongoing activities of a host operating system(OS) and all of the guest OSs from one of the guest OSs. The implementation of the program is that functionality of a linux as one of guest OSs is used to monitor real-time performance of the guests on IBM* zVM** system and the host itself through Web browser. Problem Recently a virtualized technology is focused from Total Cost of Ownership(TCO) point of view. For example, zVM, one of the IBM Operating System, is used to run many linux guests in a single hardware box and enable to reduce TCO. The main issue in the case is to monitor a host OS's resources including CPU, I/O and memory used by the guests. For example, IBM Real-time Monitor VM/ESA(RTM/ESA) which runs on the zVM is generally used in monitoring, analysis and problem solving for short period.
