SYNOPSIS

11       edac-util [OPTION]...
12

DESCRIPTION

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

OPTIONS

23       -h, --help
24              Display a summary of the command-line options.
25
26       -q, --quiet
27              Quiet  mode.  For  some reports, edac-util will report corrected
28              and uncorrected error counts for all MC, csrow, and channel com‐
29              binations,  even  if  the  current  count of errors is zero. The
30              --quiet flag will suppress the display  of  any  locations  with
31              zero  errors,  thus creating a more terse report. No output will
32              be generated if there are zero total errors  currently  recorded
33              by  EDAC. Additionally, the use of --quiet will suppress all in‐
34              formational and debug messages, displaying only fatal errors.
35
36       -v, --verbose
37              Increase verbosity. Multiple -v´s may be used.
38
39       -s, --status
40              Displays the current status of EDAC drivers. edac-util will  re‐
41              port  whether  it  detects that EDAC drivers are loaded, and the
42              number of memory controllers (MCs) found in  sysfs.  In  verbose
43              mode,  the  MC  id  and  name  of  each  controller will also be
44              printed.
45
46       -r, --report=report,...
47              Specify the report to generate. Currently, the available reports
48              are  default,  simple,  full, ue, and ce.  These reports are de‐
49              tailed in the EDAC REPORTS section below. More than  one  report
50              may be specified in a comma-separated list.

EDAC REPORTS

54       default
55              The  default  edac-util  report is generated when the program is
56              run without any options. If there are no errors logged by  EDAC,
57              this  report will display "No errors to report." to stdout. Oth‐
58              erwise, error counts for each  MC,  csrow,  channel  combination
59              with  attributed  errors are displayed, along with corresponding
60              DIMM labels, if these labels have been registered in sysfs.
61
62              The default report will also display any errors that do not have
63              any  DIMM  information.  These  errors occur when errors are re‐
64              ported in the memory controller  overflow  register,  indicating
65              that  more  than one error occurred during a given EDAC poll cy‐
66              cle. It is usually obvious from which DIMM locations  these  er‐
67              rors were generated.
68
69       simple The simple report reports total corrected and uncorrected errors
70              for each MC detected on the system. It also displays a tally  of
71              total  errors.  With  the  --quiet  option,  only non-zero error
72              counts are displayed.
73
74       full   The full report generates a line of output for every MC,  csrow,
75              channel combination found in EDAC sysfs. This includes counts of
76              errors with no information ("noinfo" errors). Output is  of  the
77              form:
78
79              MC:(csrow|noinfo):(label|all):(UE|CE):count
80
81              With the --quiet option, only non-zero error counts will be dis‐
82              played.
83
84       ue     This report simply displays the total number of Uncorrected  Er‐
85              rors  (UEs)  detected  on  the system.  With the --quiet option,
86              output will be suppressed unless there are 1 or more  errors  to
87              report.
88
89       ce     This report simply displays the total number of Corrected Errors
90              (CEs) detected on the system.  With the --quiet  option,  output
91              will be suppressed unless there are 1 or more errors to report.
