CLUE ERRLOG extracts the error log buffers from the dump file and places them into the binary file called CLUE$ERRLOG.SYS. These buffers contain messages not yet written to the error log file at the time of the failure. When you analyze a failure on the same system on which it occurred, you can run the Error Log utility on the actual error log file to see these error log messages. When analyzing a failure from another system, use the CLUE ERRLOG command to create a file containing the failing system's error log messages just prior to the failure. System failures are often triggered by hardware problems, so determining what, if any, hardware errors occurred prior to the failure can help you troubleshoot a failure. You can define the logical CLUE$ERRLOG to any file specification if you want error log information written to a file other than CLUE$ERRLOG.SYS. NOTE You need at least DECevent V2.9 to analyze the new common event header (CEH) format file. The old format file can be analyzed by ANALYZE/ERROR or any version of DECevent.
