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 combina-
	      tions, 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. Addition-
	      ally, 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 attrib-
	      uted 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 usu-
	      ally 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.
