edac-util - EDAC error reporting utility.
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.
- -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
- -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
- -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.
- 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.
- 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.
- 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
With the --quiet option, only non-zero error counts will be
- 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
- 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.
