5.2.1 Error Logging and Event Log Entry Format
The DIGITAL UNIX and OpenVMS error handlers generate several entry types.
Error entries, except for correctable memory errors, are logged immediately. Entries
can be of variable length based on the number of registers within the entry.
Each entry consists of an operating system header, several device frames, and an end
frame. Most entries have a PAL-generated logout frame, and may contain frames for
CPU, memory, and I/O.
5.3 Event Record Translation
Systems running DIGITAL UNIX and OpenVMS operating systems use the
DECevent management utility to translate events into ASCII reports derived from
system event entries (bit-to-text translations).
The DECevent utility has the following capabilities relating to the translation of
events:
• Translating event log entries into readable reports
• Selecting input and output sources
• Filtering input events
• Selecting alternate reports
• Translating events as they occur
• Maintaining and customizing the user environment with the interactive shell
commands
NOTE: Microsoft Windows NT does not currently provide bit-to-text translation of
system errors.
Section 5.3.1 describes the command used to translate the error log information for
the OpenVMS operating system using DECevent.
Section 5.3.2 describes the command used to translate the error log information for
the DIGITAL UNIX operating system using DECevent.
