man ua_uerf
NAME
ua_uerf - uerf output filter
SYNOPSIS
uerf [-options] | ua_uerf [-options]
DESCRIPTION
The Digital UNIX error reporting utility uerf and the newer dia (DECevent)
produce detailed reports which are impossible for scanning for error trend
analysis. The ua_uerf utility is a uerf filter which can summarize errors:
by type;
by day;
by grand total;
by exclusion;
by limited volumes;
by single line summary
in a form suitable for either ad hoc reporting or for daily email summaries
or for weekly|monthly management summary.
The ua_uerf utility is not a replacement for dia (or uerf), but it does
provide a quick scanning ability to determine when you need to drill deeper
into hardware errors.
ARGUMENTS
input-file
Input file specification, defaults as standard input since
typically uerf ouptut is piped directly into ua_uerf.
OPTIONS
Record Type Options
-all Show all record types (default)
-none Show no record types, implies -total
-boot Show boot|oper records
-hardware Show hardware records
-scsi Show scsi cam records
-unix Show software records
-misc Show any other record types
Filtering Options
nosummary Do not display summary information totals.
-total Show summary totals by day.
-ignore string1[,string2...]
Ignore record types with matching strings.
-keep string1[,string2...]
Keep record types with matching strings.
Used to retain records which matched -ignore.
-limit N
Limit the number of replicated records displayed for a day.
The default is 5, use zero to see only totals.
Other Options
-output output-file
To specify an output file.
-verbose To generate some debugging displays.
-? To display a terse help message.
EXAMPLES
A 132 column display is strongly recommended for ua_uerf.
The following aliases are used in the examples:
sxkac@glacier: alias | grep UERF
UA7UERF='uerf -c err,oper -o full -t s:`ua_date -uerf -7` | /usr/local/sbin/ua_uerf -a'
UAXUERF='uerf -c err,oper -o full -t s:`ua_date -uerf -30` | /usr/local/sbin/ua_uerf -a'
UA_UERF='uerf -c err,oper -o full -t s:`ua_date -uerf -1` | /usr/local/sbin/ua_uerf -a'
ua_date is a date formating routine with several pre-defined UNIX date for-
mats and the ability to specify "delta" days, such as "7 days ago" with
UA7UERF above. You can, of course, key in a date in uerf format:
sxkac@nugget: ua_date -uerf -7
03-sep-1997,00:00:00
A ua_uerf example for "yesterday" showing only 2 entries for any given type
and ignoring cdisk_rec_status errors:
sxkac@glacier: UA_UERF -l2 -i cdisk_rec_status

Normally, the UA_UERF alias is used "as is" to summarize recent errors when
investigating a problem... the example above just helps keep down the size
of this man page. Note, you must use dia to determine the BBR errors above
were soft (correctable) errors.
To find specifically when all the BBR errors occured:
sxkac@glacier: UA_UERF nosum -i cdisk,ctape -k cdisk_bbr -l20

The example above selects all scsi records, but uses -ignore to filter out
the noise (changer, ctape, and most cdisk errors).
RESTRICTIONS / NOTES
ua_uerf has been tested under DU v3.2g and v4.0b.
As stated above, a 132 column display is recommended.
Suggestions for enhancements or bug reports can be directed to
fnkac@uaf.edu.
The ua_uerf utility uses the cci command parser utilized by non-UNIX
operating systems instead of the traditional UNIX getopt() parsing.
Options have generally been defined to "look like" UNIX style options, but
can be spelled out or abbreviated in many cases. For example '-l' is the
same as '-limit'. In some cases, like 'nosummary', options must be par-
tially or fully spelled out. Required option length can be found by
ua_uerf -?. Because of this multiple options must be space separated and
the hyphen is part of the option name.
From the monthly example above, one must use dia to determine that the two
"CPU EXCEPTION" errors were single-bit correctable memory errors. Gen-
erally, that determination should occur on a daily basis. Sample scripts
for email'ing summaries and some sed filters for parsing dia BBR and CPU
errors are included with the ua_uerf distribution. If one uses meaningful
text for shutdown reason, the binary.errlog files can be used for longer
term tracking of events. Also included with the distribution is a script to
"roll" and preserve binary.errlog every four months.
ACKNOWLEDGEMENTS
The ua_uerf utility was written at the University of Alaska.
