NAME

       edac-util - EDAC error reporting utility.

SYNOPSIS

       edac-util [OPTION]...

DESCRIPTION

       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.

OPTIONS

       -h, --help
              Display a summary of the command-line options.

       -q, --quiet
              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.

       -v, --verbose
              Increase verbosity. Multiple -v´s may be used.

       -s, --status
              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 printed.

       -r, --report=report,...
              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.

EDAC REPORTS

       default
              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
              form:

              MC:(csrow|noinfo):(label|all):(UE|CE):count

              With the --quiet option, only non-zero error counts will be displayed.

       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 report.

       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.
