<p><P>PROBLEM TO BE SOLVED: To provide a data storage device and method, and a program, for efficiently storing data with a less memory capacity and processing load even when an event factor is complicated when storing the data expressing an operation state of a system in response to event occurrence of the system, and easily distinguishing the kind, factor, and condition or the like of the event in subsequent operation analysis to improve analysis performance. <P>SOLUTION: This data storage device has: an analysis target data temporary storage part 110 storing analysis target data corresponding to an acquisition frequency or the previous prescribed time; an event occurrence decision part 130 deciding the occurrence of the event from event occurrence-deciding data; an event data output part 120 outputting data related to the event occurrence decision and the event as event data; and a data storage part 140 storing the data stored in the analysis target data temporary storage part 110 in association with the event data when the occurrence of the event is decided or when the prescribed time after the occurrence of the event is decided. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
