edac-util - EDAC error reporting utility.
The edac-util program reads information from EDAC (Error Detection and
Correction) drivers in the kernel, using files exported by these
drivers in sysfs. With no options, edac-util will report any
uncorrected error (UE) or corrected error (CE) information recorded by
EDAC, along with any DIMM label information registered with EDAC.

Quiet mode. For some reports, edac-util will report corrected
and uncorrected error counts for all MC, csrow, and channel
combinations, even if the current count of errors is zero. The
--quiet flag will suppress the display of any locations with
zero errors, thus creating a more terse report. No output will
be generated if there are zero total errors currently recorded
by EDAC. Additionally, the use of --quiet will suppress all
informational and debug messages, displaying only fatal errors.
Increase verbosity. Multiple -v´s may be used.
Displays the current status of EDAC drivers. edac-util will
report whether it detects that EDAC drivers are loaded, and the
number of memory controllers (MCs) found in sysfs. In verbose
mode, the MC id and name of each controller will also be
Specify the report to generate. Currently, the available reports
are default, simple, full, ue, and ce. These reports are
detailed in the EDAC REPORTS section below. More than one report
may be specified in a comma-separated list.
The default edac-util report is generated when the program is
run without any options. If there are no errors logged by EDAC,
this report will display "No errors to report." to stdout.
Otherwise, error counts for each MC, csrow, channel combination
with attributed errors are displayed, along with corresponding
DIMM labels, if these labels have been registered in sysfs.
The default report will also display any errors that do not have
any DIMM information. These errors occur when errors are
reported in the memory controller overflow register, indicating
that more than one error occurred during a given EDAC poll
cycle. It is usually obvious from which DIMM locations these
errors were generated.
simple The simple report reports total corrected and uncorrected errors
for each MC detected on the system. It also displays a tally of
total errors. With the --quiet option, only non-zero error
counts are displayed.
full The full report generates a line of output for every MC, csrow,
channel combination found in EDAC sysfs. This includes counts of
errors with no information ("noinfo" errors). Output is of the

ue This report simply displays the total number of Uncorrected
Errors (UEs) detected on the system. With the --quiet option,
output will be suppressed unless there are 1 or more errors to
ce This report simply displays the total number of Corrected Errors
(CEs) detected on the system. With the --quiet option, output
will be suppressed unless there are 1 or more errors to report.
