7 edac-util - EDAC error reporting utility.

11 edac-util [OPTION]...
12
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.
20
23 -h, --help
24 Display a summary of the command-line options.
25 -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 -v, --verbose
37 Increase verbosity. Multiple -v´s may be used.
38 -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 -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.
51
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 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 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 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 MC:(csrow|noinfo):(label|all):(UE|CE):count
80 With the --quiet option, only non-zero error counts will be dis‐
82 played.
83 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 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.
