A computer system is reliably protected from unauthorized access. The present invention provides a computer system comprising a plurality of service computers each capable of performing predetermined services, and a management computer which manages each of the plurality of service computers. Each of the plurality of service computers comprises a controller which executes an operating system, and a management processor for managing computer hardware. The controller executes a monitoring program which manages predetermined events. The management processor sends information of a detected event to the management computer via a port for connecting to the management computer.

Computer system and control method thereof

A computer includes: a host VM monitor configured to operate on a physical processor and generate a logical processor that operates a first-level VM; and a guest VM monitor configured to operate on the logical processor and generate a plurality of virtual processors that operates a plurality of second-level VMs generated on the first-level VM. The host VM monitor includes management information that correlates control information which is unique to each of the second-level VMs and which the host VM monitor can acquire in a period from the start to the end of execution of the second-level VM with a second-level VM identifier for specifying the second-level VM. The host VM monitor specifies a second-level VM, based on a second-level VM identifier corresponding to the control information of the second-level VM, which has been acquired, in the management information and acquires information on a load of the second-level VM.

Measuring accumulated load values of first level and second level virtual machines for modifying resource allocation

A rebar structure includes a plurality of column longitudinal bars to be connected to a beam. The yield point or the 0.2% proof stress of at least a portion the column longitudinal bars is larger than the yield point or the 0.2% proof stress of a normal reinforcing bar defined by JIS G 3112.
