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.
