Abstract

A reprographic system having the capability to log system errors dynamically during system operation must provide a means for retrieval of the error log file, a concatenation of information logs associated with individual software modules, subsequent to a system software or hardware malfunction or crash. In a large reprographic system, the error log file for all the software modules contained within the system can easily exceed 0.5 megabytes of information. Current technology enables the use of external or host diagnostic systems, via remote communications capability within the reprographic system, to interactively access and analyze the error log file of an errant machine subsequent to a crash. Unfortunately, to transmit a typical error log file to a remote diagnostic system would take an inordinate amount of time. Accordingly, the present system employs a directory structure for organization of the logs contained within the error log file. More specifically, the error log file directory enumerates the logs contained within the error log file, including information pertaining to the location of each log in the error log file. Upon accessing the error log file, an external diagnostic system may first retrieve the directory to decide which logs to subsequently retrieve, as well as, the locations from which to retrieve them. In general, use of an error log file directory reduces the time required for transmission of non-essential log information, thereby improving the responsiveness of the remote diagnostic system.
