Do you mean iostat -en? Anyway, this information is available to anyone who reads the man page:
-n: shows the device names in the descriptive format. (cxtxdx instead of sd0, so that we can actually see which disk has the errors).
-m: reports on filesystem mountpoints. I doubt if this will be much use with the '-e' switch.
Hi all, hope you are having a nice day, its nice and warm today in Canberra Australia.
iostat -e / -E reports soft and hard errors. Any idea what these are exactly? All I hear are I/O's failing and needing to retry, but no cause as to why they fail.

So I use Cacti for monitoring IO statistics on my servers, now originally I couldnt monitor Multipath deviced servers as they have alot of /dev/sdxx and /dev/emcpowerxx, I have devised a method of trimming them down to just the actual devices but the issue is the output looks like so.

Friends,

On linux i have to run iostat command and in each iteration have to print the greatest value in each column.

Hi Guys,
I've been having some arguments with my colleagues about one thing. Always my thought was that as as far as disk performance is concern by looking at the output of the iostat command (AIX) you would be able to identify if you have a hot disk and then by moving some files out that disk...

My scheduled collection of statistics is giving very large output because of an high number of ssd device not associated to any disk
The iostat -x command is collecting statistics from them and the output is very large.

edac-util
EDAC-UTIL(1) EDAC error reporting utility EDAC-UTIL(1)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.
