PURPOSE:To efficiently perform remote maintenance and diagnosis by detecting the abnormality of a system to store its information in a storage area and discriminating whether overflow occurs or not and generating a message of overflow in the case of overflow to send this message to a remote computer. CONSTITUTION:At the time of detecting the abnormality of a data processing system during operation, an abnormality detecting means 17 starts a trouble information gathering means 18. A microprogram execution control part 11 starts a trouble information storage means 20 to write trouble information in a trouble information storage area of a defined area of a local memory 12 and starts a storage condition discriminating means 21; and when overflow of the trouble information storage area is discriminated, the dial number stored in a dial register 15 is read out and the message of storage area overflow is generated to start a transfer request means 19. Then, the transfer request means 19 requests a communication control means 16 to transfer the message to a remote computer (maintenance center) 6 through a public line 9. |
