Using the uerf Event Logger
Use the uerf command to produce event reports from the binary log file.
You must be superuser to use the uerf command. The uerf command
accesses events logged to the binary log file, translates them from binary
code to ASCII if necessary, and sends them to the output device you specify.
The events include error messages relating to the system hardware and the
software kernel, as well as information about system status, startup, and
diagnostics. The default binary log file is /usr/adm/binary.errlog.
By reviewing the types and the number of events, you can determine the
reliability of a system. If a report shows a large number of errors for a
particular device, you can determine if a problem exists before the device
fails completely. Furthermore, if a failure occurs, the event report provides
information on the events that led to the failure.
The uerf component will be retired in a future release of the Tru64 UNIX
operating system. The replacement event logger is the DECevent utility.
For more information about DECevent, see the DECevent Translation and
Reporting Utility documentation, Chapter 13, and dia
(8).
This release also includes Compaq Analyze, which supports newer
processors. Refer to the Installation Guidefor information on installing
Compaq Analyze and on accessing the documentation.
The uerf command uses the following three data files:
• /usr/sbin/uerf.bin − The event information database
• /usr/sbin/uerf.hlp − The help file
• /usr/sbin/uerf.err − The error message file
The uerf command allows you to specify the source that it uses to
generate event reports, to restrict the event selection, and to produce
specific output formats. The uerf command has the following syntax:
/usr/sbin/uerf
[ options...]
Without options, the uerf command outputs the contents of the event-log
file specified by the *.* entry in the /etc/binlog.conf configuration file.
