<p><P>PROBLEM TO BE SOLVED: To provide a task log extraction device capable of accurately acquiring a task log by an operation of an operation worker in an operation management task of a communication network without burdening any load on the operation worker and without increasing a load of an operation terminal for operation management. <P>SOLUTION: A packet processing unit 9 collects packets from a network for operation management, and extracts access destination information and write information of the packets. An image information processing unit 10 acquires image information within a predetermined period before and after a screen change occurs on an operation management terminal. A history information extraction unit 11 extracts only data relating to an operation management task of a communication network from the access destination information and the write information from the packet processing unit 9, and the image information from the image information processing unit 10. A time synchronization unit 13 gives the data from the history information extraction unit 11 a time stamp. The data given the time stamp is stored in a history storage unit 12 as a task log. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
