Abstract

PURPOSE: To secure the effective application of a store area for action state information and to hold the information of high accuracy for a long period of time, by adding a tracing time point and the importance degree of information to the action state information of hardware as the control information.
CONSTITUTION: An action state information collecting mechanism 112 is started by an event detecting mechanism 111 and collects the trace information on a device 100 to be traced. A control information adding mechanism 114 adds the importance degree stored in an action state information importance degree memory mechanism 113 and the collecting time point information on the trace information clocked by a clock mechanism 115 to the trace information of the device 100. Then a store area control mechanism 116 checks the idle state of the store area of an external memory device 120 and refers to the time point and the importance degree added to the action state information if no idle area is detected and selects the oldest action state information having a low degree of importance. Then the new action state information is stored (overlayed) into the store area of the selected action state information. Thus it is possible to use effectively the store area of the action state information and to hold the information of high accuracy for a long period of time.
