ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to an error monitoring system including a CPU (Central Processing Unit) and a data output terminal and, more particularly, to an error reporting system for an error monitoring system.
An error monitoring system for monitoring devices included in the system and sending error information representative of errors to the outside of the system is conventional. Today, not only a display and a printer but also a facsimile apparatus and an electronic mail using a telephone circuit are usable with the error monitoring system. However, the kinds and amounts of information which can be output are limited by the outputting capability of a display or that of a printer. Moreover, the error information include only minimum necessary information to be output to a display or a printer connected to the system. Specifically, in the event of a critical error, necessary information are too much in amount to be fully output. As a result, although the occurrence of an error may be reported, it is often impractical to remove the error only with the output information. This requires a person to obtain additional information by communicating with or traveling all the way to a station where the system is situated. In addition, because the error information are fixed, not all necessary information are output in the event of an error. This is likely to prevent all necessary information from being collected when an error occurs again.
Technologies relating to the present invention are disclosed in, e.g., Japanese Patent Laid-Open Publication Nos. 2-51925, 2-283137, 3-101539, 4-109728, 5-227316, 5-244300, 7-255087, 7-297826, and 7-321913.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide an error information reporting system capable of reporting, when a critical error occurs, all necessary information to all necessary destinations immediately, thereby obviating confusion in the event of data collection and enhancing rapid removal of the error.
An error information reporting system of the present invention includes an error information outputting unit. An interface controls the error information outputting unit. A desired device is monitored as to an error thereof. A CPU detects error information representative of an error occurred in the device, searches for a key word corresponding to the error information, references a collected error information table listing collected error information corresponding to the key word, selects the collected error information corresponding to the key word out of the collected error information table, and sends the collected error information to a destination corresponding to the kind of the error represented by the collected error information by using transmitting means assigned to the destination.
