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.
