Abstract

A method is described where analysis programs created by the user can be interfaced into IBM-developed programs. Hardware error logging is a process for gathering data (bits and bytes) about a realtime system failure during realtime by the failing system. This data is stored on a nonvolatile media. Error Log Analysis is a procedure or set of programs that helps interpret the nature of the failure and possible cause, and might also specify some action to be performed. Many systems perform error analysis functions of hardware errors. If an error is detected, many systems will log the raw bits and bytes, which are captured at the time of the error. They will provide a means to display this error record. They may perform some analysis on that error record.

Error Log and Analysis Supports for User-Written Analysis Programs

A method is described where analysis programs created by the user can be interfaced into IBM-developed programs. Hardware error logging is a process for gathering data (bits and bytes) about a realtime system failure during realtime by the failing system. This data is stored on a nonvolatile media. Error Log Analysis is a procedure or set of programs that helps interpret the nature of the failure and possible cause, and might also specify some action to be performed. Many systems perform error analysis functions of hardware errors. If an error is detected, many systems will log the raw bits and bytes, which are captured at the time of the error. They will provide a means to display this error record. They may perform some analysis on that error record. Most, if any, do not support a user interface where the user can design and code his own error logging and analysis programs, and interface them into the IBM-developed logging programs, analysis programs and report generators. The realtime hardware error handling package for the IBM PC/RT consists of error logging, error analysis, and error report. The Error Logging design allows any program to log an error log record. The Error Logging provides interfaces at the Virtual Resource Manager (VRM) level, the UNIX* kernel level and the UNIX application level. This provides the means for a VRM device driver to log errors or events, the UNIX device driver to log errors or events, and any UNIX application program to log errors or events. Error analysis is done at the UNIX application level and is an in-line process with Error Logging. This means that analysis is done before the complete error record is stored on the hard file.
