SYSTEM FOR ACQUIRING INSIDE INFORMATION OF VIRTUAL MACHINE

PROBLEM TO BE SOLVED: To realize an inside information acquiring system for acquiring and outputting the inside information data of a virtual machine capable of reducing data amounts to be outputted. SOLUTION: At the time of acquiring inside information from a virtual machine 2, an inside information acquiring means 11 writes the acquired inside information data in an input buffer 121. A data compressing part 122 compresses the data of the input buffer 121 by variable length encoding processing or dictionary base compression processing, and a data outputting means 13 outputs the data processed by the data compressing part 12 to an output file 3.
